Workweek and weekend
The weekdays and weekend are the complementary parts of the week devoted to labour and rest, respectively. The legal weekdays (British English), or workweek (American English), is the part of the seven-day week devoted to working. In most of the world, the workweek is from Monday to Friday and the weekend is Saturday and Sunday. A weekday or workday is any day of the working week. Other institutions often follow this pattern, such as places of education. The constituted weekend has varying definitions, based on determined calendar days, designated period of time, and/or regional definition of the working week (e.g., commencing after 5:00 p.m. on Friday and lasting until 6:00 p.m. on Sunday). Sometimes the term "weekend" is expanded to include the time after work hours on the last workday of the week (e.g., Friday evening is often referred to as the start of the weekend).
In some Christian traditions, Sunday is the "day of rest and worship". The Jewish Shabbat or Biblical Sabbath lasts from sunset on Friday to the fall of full darkness on Saturday; as a result, the weekend in Israel is observed on Friday–Saturday. Some Muslim-majority countries historically instituted a Thursday–Friday weekend. Today, many of these countries, in the interests of furthering business trade and cooperation, have shifted to Friday–Saturday or Saturday–Sunday as in the case of Saudi Arabia and UAE.The Christian day of worship is just one day each week, but the preceding day (the Jewish Sabbath) came to be taken as a holiday as well in the 20th century. This shift has been accompanied by a reduction in the total number of hours worked per week. The present-day concept of the "weekend" first arose in the industrial north of Britain in the early  19th century. The Amalgamated Clothing Workers of America union was the first to successfully demand a five-day work week in 1929.
Some countries have adopted a one-day weekend, i.e. either Sunday only (in seven countries), Friday only (in Djibouti and Somalia), or Saturday only (in Nepal and in Israel). However, most countries have adopted a two-day weekend, whose days differ according to religious tradition, i.e. either Friday and Saturday, or Saturday and Sunday, or Friday and Sunday (in Brunei Darussalam, Aceh province (Indonesia) and state of Sarawak (Malaysia)), with the previous evening post-work often considered part of the weekend. Proposals continue to be put forward to reduce the number of days or hours worked per week, on the basis of predicted social and economic benefits.

History
A continuous seven day cycle that runs throughout history, paying no attention whatsoever to the phases of the moon and having a fixed day of rest, was most likely first practised in Judaism, dated to the 6th century BC at the latest.In Ancient Rome (753 BC–476 AD), every eight days there was a nundinae. It was a market day, during which children were exempted from school and agricultural workers stopped work in the field and came to the city to sell the produce of their labor or to practice religious rites.The French Revolutionary Calendar (1793–1805) had ten-day weeks (called décades) and allowed décadi, one out of the ten days, as a leisure day. From 1929 to 1940, the Soviet Union utilized a calendar with five and six-day work weeks, with a rest day assigned to a worker either with a colour or number.
In cultures with a four-day workweek, the three Sabbaths derive from the culture's main religious tradition: Friday (Muslim), Saturday (Jewish, Adventist), and Sunday (Christian).
The present-day concept of the relatively longer 'week-end' first arose in the industrial north of Britain in the early 19th century and was originally a voluntary arrangement between factory owners and workers allowing Saturday afternoon off starting at 2 pm on the basis that staff would be available for work sober and refreshed on Monday morning. The Oxford English Dictionary traces the first use of the term weekend to the British magazine Notes and Queries in 1879.In 1908, the first five-day workweek in the United States was instituted by a New England cotton mill so that Jewish workers would not have to work on the Sabbath from sundown Friday to sundown Saturday. In 1926, Henry Ford began shutting down his automotive factories for all of Saturday and Sunday, realizing that by giving workers more time off it would encourage more leisure activities such as vacations and shopping. In 1929, the Amalgamated Clothing Workers of America was the first union to demand and receive a five-day workweek. The rest of the United States slowly followed, but it was not until 1940, when a provision of the 1938 Fair Labor Standards Act mandating a maximum 40-hour workweek went into effect, that the two-day weekend was adopted nationwide.Over the succeeding decades, particularly in the 1940s to 1960s, an increasing number of countries adopted either a Friday–Saturday or a Saturday–Sunday weekend to harmonize with international markets. A series of workweek reforms in the mid-to-late 2000s and early 2010s brought much of the Arab World in synchronization with the majority of countries around the world, in terms of working hours, the length of the workweek, and the days of the weekend. The International Labour Organization (ILO) currently defines a workweek exceeding 48 hours as excessive. A 2007 study by the ILO found that at least 614.2 million people around the world were working excessive hours.

Length
Actual workweek lengths have been falling in the developed world. In the United States, the workweek length reduced slowly from before the Civil War to the start of the 20th century. There was a rapid reduction between 1900 and 1920, especially between 1913 and 1919, when weekly hours fell by about eight percent. In 1926, Henry Ford standardized on a five-day workweek, instead of the prevalent six days, without reducing employees' pay. Hours worked stabilized at about 49 per week during the 1920s, and during the Great Depression fell below 40. During the Depression, President Herbert Hoover called for a reduction in work hours in lieu of layoffs. Later, President Franklin Roosevelt signed the Fair Labor Standards Act of 1938, which established a five-day, 40-hour workweek for many workers. The proportion of people working very long weeks has since risen, and the full-time employment of women has increased dramatically.The New Economics Foundation has recommended moving to a 21-hour standard workweek to address problems with unemployment, high carbon emissions, low well-being, entrenched inequalities, overworking, family care, and the general lack of free time. The Center for Economic and Policy Research states that reducing the length of the work week would slow climate change and have other environmental benefits.

Around the world
Table
Africa
Ethiopia
The official government working week is Monday to Friday; 8 hours per day, except Friday which is 7 hours, and 39 hours in total per week. Official work hours run from 08:30 am to 05:30pm with 1 hour for lunch from 12:30pm to 01:30pm. On Friday, lunch hour runs from 2:00 am to 6:00  to allow Muslims attend to Friday prayers. Saturday and Sunday are public holidays. The private sector often follows different schedule with most of them often working on Saturdays.

Morocco
Despite being an Islamic country, Morocco does not follow workweek conventions implemented in many Middle Eastern countries. The standard workweek in Morocco is from Monday to Friday, with Saturday and Sunday being public holidays.

South Africa
In South Africa the working week traditionally was Monday to Friday with a half-day on Saturday and Sunday a public holiday. However, since 2013 there have been changes to the working week concept based on more than one variation. The week can be 5 days of work, or more. The maximum number of hours someone can work in a week remains 45.

Americas
Brazil
As a general rule, Brazil adopts a 44-hour working week, which typically begins on Monday and ends on Friday, with a Saturday–Sunday weekend. Brazilian Law, however, also allows for shorter Monday-to-Friday working hours so employees can work on Saturdays or Sundays, as long as the weekly 44-hour limit is respected and the employee gets at least one weekend day. This is usually the case for malls, supermarkets and shops. The law also grants labor unions the right to negotiate different work weeks, within certain limits, which then become binding for that union's labor category. Overtime is allowed, limited to two extra hours a day, with an increase in pay.

Chile
The working week in Chile averages 45 hours, most often worked on a Monday–Friday schedule, but is not uncommon to work on Saturdays. Retail businesses mostly operate Monday through Saturday, with larger establishments being open seven days a week.

Colombia
In general, Colombia has a 48-hour working week. Depending on the business, people work five days for a maximum of 8 hours per day, typically Monday to Friday, or six days for eight hours a day, Monday to Saturday. In 2021, the Government enacted a law that reduces the weekly working hours from 48 to 42, which will take effect gradually between 2023 and 2026.

Mexico
Mexico officially has a 48-hour workweek (8 hours × 6 days) running from Monday to Saturday, although it is uncommon in most industries to consistently work six full days per week. It is the custom in many industries and trades to work a half-day on Saturdays. Most public employees have a five-day workweek running from Monday to Friday, and many white-collar businesses use this schedule as well. Shops and retailers remain open on Saturday and Sunday in most large cities.

United States
Since the early to mid-20th century the working week in the United States traditionally begins on Monday and ends on Friday, 40 hours per week, with Saturday and Sunday being weekend days. However, in practice, only 42% of employees work 40-hour weeks. The average workweek for full-time employees is 47 hours. Retail stores and restaurants are generally also open for business on Saturday and often on Sunday as well, except in some places where prohibited by law (see Blue law). Increasingly, employers are offering compressed work schedules to employees. Some government and corporate employees now work a 9/80 work schedule (80 hours over 9 days during a two-week period)—commonly 9-hour days Monday to Thursday, 8 hours on one Friday, and off the following Friday. Some government or corporate employees work a 10/40 schedule—10 hours per day over 4 days, usually with Fridays off. Jobs in healthcare, law enforcement, transportation, retail, and other service positions commonly require employees to work on the weekend or to do shift work.

Asia and Australasia
Australia
A five-day, 40-hour week was introduced nationally from 1 January 1948 following a ruling of the Commonwealth Court of Conciliation and Arbitration. A 44-hour week, usually taken as a half-day on Saturday, had been applied for some industries from 1927 following a ruling by the court in a case brought by the Amalgamated Engineering Union. The ruling "led to a gradual and more general reduction of hours across industries", culminating in a nationwide 44-hour week in 1939.In Australia the working week begins on Monday and terminates on Friday. An eight-hour working day is the norm. Working three weekdays a fortnight, for example, would therefore be approximately twenty-four hours (including or excluding traditional breaks tallying up to two hours). Some people work overtime with extra pay on offer for those that do, especially for weekend work. Shops open seven days a week in most states with opening hours from 9am to 5:30 pm on weekdays, with some states having two "late night trading" nights on Thursday and Friday, when trading ceases at 9pm. Many supermarkets and low-end department stores remain open until midnight and some trade continually, without closing. Restaurants and cinemas can open at all hours, save for some public holidays. Bars generally trade seven days a week but there are local municipal restrictions concerning trading hours. Banks trade from Monday to Friday, with some branches opening on Saturdays (and in some cases Sundays) in high demand areas. The Post Office (Australia Post) trades Monday to Friday as per retail shops but some retail post offices may trade on Saturdays and Sundays in some shopping centers. A notable exception to the above is South Australia whereby retail establishments are restricted to trading between the hours of 11am-5pm on Sundays.

China
In China, there is a five-day Monday–Friday working week, prior to which work on Saturday was standard. China began the two-day Saturday–Sunday weekend on May 1, 1995. Most government employees work 5 days a week (including officials and industrial management). Most manufacturing facilities operate on Saturdays as well. However, most shops, museums, cinemas, and commercial establishments open on Saturdays, Sundays, and holidays. Banks are also open throughout the weekend and on most public holidays.
During the period of public holidays, swapped holidays are common between the actual holiday and weekend, so three-day or seven-day holiday periods are created. The nearby Saturday or Sunday may be changed to a normal working day. For example, on a three-day holiday period, if the actual holiday falls on a Tuesday, Monday will be swapped as a holiday, and citizens are required to work on the previous Saturday.
A number of provinces and municipalities across China, including Hebei, Jiangxi and Chongqing, have issued new policies, calling on companies to create 2.5-day weekends. Under the plan, government institutions, state-owned companies, joint-ventures and privately held companies are to be given incentives to allow their workers to take off at noon on Friday before coming back to the office on Monday.
Hong KongIn Hong Kong, a typical working week for local enterprises begins on 9am on Monday and ends at 1pm on Saturday, although most employees have alternate Saturdays off. After the introduction of the five-day working week for the majority of government departments in 2006, most multinational enterprises and large local companies followed suit, extended the working day from 9am to 5pm so as to adopt a five-day work week. Despite the aforementioned official hours, and many employees still work overtime, and in the case of the financial, service and artist industry in particular, working 12-hour days on a chronic basis is still not uncommon.
Most commercial establishments in the retail sector such as restaurants, shops and cinemas, as well as public venues such as museums and libraries are open on Saturdays, Sundays and most public holidays. For schools, lessons are not normally held on Saturdays, but students may be required to go school on Saturdays for extra-curricular activities or make-up classes.

India
The standard working week for most office jobs begins on Monday and ends on Saturday. The work schedule is 48 hours per week, Sunday being a rest day. However, most government offices and the software industry follow a five-day workweek. All major industries along with services like transport, hospitality, healthcare etc. work in shifts.
Central government offices follow a five-day week. State governments follow half-day working on the first and third Saturdays of each month and rest on the second and fourth Saturdays, except West Bengal, Rajasthan, Bihar, Punjab, Delhi, Tamil Nadu, and Maharashtra government which follows a Monday–Friday workweek. There is usually no half working day in the private sector, and people work in two or three shifts of 8 hours each.
Most schools follow a six-day workweek from Monday to Saturday. Banks have 2nd and 4th Saturday off in India starting from Sep 1st, 2015.

Iran
The standard working week in Iran begins on Saturday and ends on Thursday. Thursdays are usually half-day working days. Many private enterprises which operate on an 8 to 5 basis take Thursdays off for a two-day Thursday-Friday weekend. These variations allow employers flexibility in choosing working hours so that the legal requirement of working for 44 hours per week is met. However, shopping places are usually open for business on Friday as well.

Israel
In Israel, the standard workweek is 42 hours as prescribed by law. The typical workweek is five days, Sunday to Thursday, with 8.4 hours a day as the standard, with anything beyond that considered overtime. A minority of jobs operate on a partial six-day Sunday–Friday workweek.
 Many Israelis work overtime hours, with a maximum of 12 overtime hours a week permitted by law. Most offices and businesses run on a five-day week, though many stores, post offices, banks, and schools are open and public transportation runs six days a week. Almost all businesses are closed during Saturday, and most public services except for emergency services, including almost all public transport, are unavailable on Saturdays. However, some shops, restaurants, cafes, places of entertainment, and factories are open on Saturdays, and a few bus and share taxi lines are active. Employees who work Saturdays, particularly service industry workers, public sector workers, and pilots, are compensated with alternative days off. In 2014, the average workweek was 45.8 hours for men and 37.1 hours for women.

Japan
The standard business office working week in Japan begins on Monday and ends on Friday, 40 hours per week. This system became common between 1980 and 2000. Before then, most workers in Japan worked full-time from Monday to Friday and a half day on Saturday, 45–48 hours per week. Public schools and facilities (excluding city offices) are generally open on Saturdays for half a day.

Nepal
Nepal follows Bikram Sambat (BS) calendar,  which has the resting day on Saturday and the first day of the working week on Sunday. Workweek starts on Sunday and ends on Friday. Schools in Nepal are off on Saturdays, so it is common for pupils to go to school from Sunday to Friday.
In November 2012, the home ministry proposed a two-day holiday per week plan for all government offices except at those providing essential services like electricity, water, and telecommunications. This proposal followed a previous proposal by the Nepali government, i.e. Load-shedding Reduction Work Plan 2069 BS, for a five working day plan for government offices as part of efforts to address the problem of load-shedding. The proposal has been discussed in the Administration Committee; it is not yet clear whether the plan includes private offices and educational institutions.

New Zealand
In New Zealand the working week is typically Monday to Friday 8:30 to 17:00, but it is not uncommon for many industries (especially construction) to work a half day on Saturday, normally from 8:00 or 9:00 to about 13:00. Supermarkets, malls, independent retailers, and increasingly, banks, remain open seven days a week.

Philippines
In the Philippines, Article 91 of the Labor Code requires at least one rest day for workers in a week; the choice of selecting the rest day is left to the employer, subject to collective bargaining. Most workers avail of Sunday as their mandated rest day. However, government offices, banks, and many non-service industry establishments maintain a five-day (Monday to Friday) work week.

Thailand
In Thailand the working week is Monday to Friday for a maximum of 44 to 48 hours per week (Saturday can be a half or full day).However, government offices and some private companies have modernised through enacting the American and European standard of working Monday through Friday.Currently, 50% of the luxury beach resorts in Phuket have a five-day working week. Of the remaining 50%, 23% have taken steps to reform their 6-day workweek through such measures as reducing the working week from 6 days to 5.5 days.

Vietnam

Workers are not obliged to work on Sunday; on 23 April 1919, the 8-hour-day, 48-hour-workweek rule was established. School children have traditionally taken Wednesday off, or had only a half day, making up the time either with longer days for the rest of the week or sometimes a half day on Saturday. This practice was made much less common under new legislation rolled out over 2013–14.

In 2019, additional restrictions limited trading to the last Sunday of every month. Then, in 2020, trading was prohibited on all but Sundays each year, including those leading up to Christmas and Easter.
Bakeries, confectioners, petrol stations, florists, post offices, train stations and airports will be exempt from the ban. Owners will be able to open their shops as long as they serve customers themselves.

Russia
In Russia the common working week begins on Monday and ends on Friday with 8 hours per day.
Federal law defines a working week duration of 5 or 6 days with no more than 40 hours worked. In all cases Sunday is a holiday. With a 5-day working week the employer chooses which day of the week will be the second day off. Usually this is a Saturday, but in some organizations (mostly government), it is Monday. Government offices can thereby offer Saturday service to people with a normal working schedule.
There are non-working public holidays in Russia; all of them fall on a fixed date. By law, if such a holiday coincides with an ordinary day off, the next work day becomes a day off. An official public holiday cannot replace a regular day off. Each year the government can modify working weeks near public holidays in order to optimize the labor schedule. For example, if a five-day week has a public holiday on Tuesday or Thursday, the calendar is rearranged to provide a reasonable working week.
Exceptions include occupations such as transit workers, shop assistants, and security guards. In many cases independent schemes are used. For example, the service industry often uses the X-through-Y scheme (Russian: X через Y) when every worker uses X days for work and the next Y days for rest.

Soviet UnionIn the former Soviet Union the standard working week was 41 hours: 8 hours, 12 minutes, Monday to Friday. Before the mid-1960s there was a 42-hour 6-day standard working week: 7 hours Monday to Friday and 6 hours on Saturday.

Most shops are open on Saturday mornings and many of the larger shopping malls are open all day Saturday and in some cities like Madrid, they are open most Sundays. Some restaurants, bars, and shops are closed Mondays, as Mondays are commonly a slow business day.

Sweden
In Sweden, the standard working week is Monday to Friday, both for offices and industry workers. The standard workday is eight hours, although it may vary greatly between different fields and businesses. Most office workers have flexible working hours and can largely decide themselves on how to divide these over the week. The working week is regulated by Arbetstidslagen (Work time law) to a maximum of 40 hours per week. The 40-hour-week is however easily bypassed by overtime. The law allows a maximum of 200 hours overtime per year. There is however no overseeing government agency; the law is often cited as toothless.Shops are almost always open on Saturdays and often on Sundays, supermarkets and shopping centres, so that employees there have to work. Traditionally, restaurants were closed on Mondays if they were opened during the weekend, but this has in recent years largely fallen out of practice. Many museums do however still remain closed on Mondays.

Employers can make their employees work every day of a week, although the employer is required to allow each employee breaks of either a continuous period of 24 hours every week or a continuous period of 48 hours every two weeks.
Laws for shop opening hours differ between Scotland and the rest of the UK. In England, Wales, and Northern Ireland, many shops and services are open on Saturdays and increasingly so on Sundays as well. In England and Wales, stores' maximum Sunday opening hours vary according to the total floor space of the store. In Scotland, however, there is no restriction in law on shop opening hours on a Sunday.
Under the EU Working Time Directive (which continues to remain UK law), workers cannot be forced to work for more than 48 hours per week on average. However, the UK allows individuals to opt out if they so choose. Individuals can choose to opt in again after opting out, even if opting out was part of their employment contract. It is illegal to dismiss them or treat them unfairly for so doing – but they may be required to give up to 3 months notice to give the employer time to prepare, depending on what their employment contract says.The minimum holiday entitlement is now 28 days per year, but that can include public holidays, depending on the employee's contract. England & Wales have eight, Scotland has nine, and Northern Ireland has ten permanent public holidays each year. The 28 days holiday entitlement means that if the government creates a one-off public holiday in a given year, it is not necessarily a day off and it does not add 1 day to employees' holiday entitlement – unless the employer says otherwise, which some do.

Muslim-majority countries
Thursday–Friday weekend
In Islam, Friday is the weekly day of prayer when Jumu'ah prayers take place. For this reason, most of the Middle Eastern countries and some other predominantly Muslim-majority countries used to consider Thursday and Friday as their weekend. However, this weekend arrangement is no longer observed by a significant number of Muslim-majority countries (see below).

Friday weekend (One day weekend)
Just two Muslim-majority countries have Friday as the only weekend day and a six-day working week.

In Iran, Thursday is half a day of work for most public offices and all schools are closed, but for most jobs, Thursday is a working day. Private and foreign companies however normally have Friday and Saturday as their weekend.
In Djibouti, many offices also tend to open early – around 7:00 or 8:00, then close at 13:00 or 14:00, especially during the summer due to the afternoon heat.

Friday–Saturday weekend
Jordan was the first Middle Eastern Arab country to shift to a Friday–Saturday weekend arrangement in January 2000. Other Arab states followed in the coming years. Following reforms in a number of Arab states in the Persian Gulf in the 2000s and 2010s, the Thursday–Friday weekend was replaced by the Friday–Saturday weekend. This change provided for the Muslim offering of Friday prayers and afforded more work days to coincide with the working calendars of international financial markets.

Saturday–Sunday weekend
Other countries with Muslim-majority populations or significant Muslim populations follow the Saturday–Sunday weekend, such as Indonesia, Lebanon, Turkey, Tunisia and Morocco. While Friday is a working day, a long midday break is given to allow time for worship.

Indonesia – With the exception of Aceh, due to prayer time for Muslims on Friday, the lunch break is extended for 2 hours or more. Shopping malls are always open and very crowded on Saturday and Sunday. Thus, some banks offer weekend banking services, especially for branches located in or near shopping malls.
Malaysia – The Monday-Friday work week is observed in most of the country especially the capital Kuala Lumpur. The states of Kedah, Kelantan, Terengganu and Johor however observe a Sunday-Thursday work week. Johor had previously followed a Monday-Friday work week between 1994 and 2013.
Mauritania (2014)
Morocco – The working week is Monday to Friday, 8 hours per day, 40 hours in total per week.
Pakistan follows the standard international 40-hour working week, from Monday to Friday, with Saturday and Sunday being the weekend. However, in many schools and enterprises, Friday is usually considered a half-day. The public sector weekend is Sunday only.
Senegal – The working week is Monday to Friday, with a large break on Friday afternoon.
Tunisia – The working week is Monday to Friday; 8 hours per day, 40 hours in total per week.
Turkey – Working above 45 hours is considered overtime, and the employer is required to pay 1.5 times the hourly wage per hour.
United Arab Emirates (2022) – Friday is half working day from 8 am until noon. Jumu'ah prayer would be at 1 pm.

Non-contiguous working week
There are some areas that unusually implement a non-contiguous workweek (Monday–Thursday and Saturday) and weekend (Friday and Sunday), as listed below.

Brunei Darussalam is the only country in the world that has a non-contiguous working week, consisting of Monday to Thursday plus Saturday. The resting days are Friday, that a significant part of the population devotes to Jumu'ah prayers, and Sunday. Some non-government companies in Brunei adopt the working week of Monday to Friday. Depending on the company rules, employees may be required to work half-day on Saturday.
The Indonesian province of Aceh is the only province that currently uses the non-contiguous working week, consisting of Monday to Thursday plus Saturday. Resting days are Friday, often used for Friday prayers, and Sunday. Some private and foreign businesses and companies in Aceh however adopted the Monday-Friday workweek.
Malaysia – Since 1 January 2020, Sarawak state government introduced a non-contiguous weekend of Friday and Sunday, replacing the former Saturday–Sunday weekend. This means the East Malaysian state is the only state in Malaysia that has a non-contiguous working week, consisting of Monday–Thursday and Saturday. Unlike Brunei Darussalam and the Aceh province in Indonesia, such implementation is meant to accommodate the Muslim and Christian communities, both very large, that respectively observe Friday and Sunday as a prayer day.
