islamic calendar how many days in a non leap year
Islamic calendar The Islamic, Muslim, or Hijri calendar (Arabic: التقويم الهجري‎ at-taqwīm al-hijrī) is a lunar calendar consisting of 12 months in a year of 354 or 355 days. It is used (often alongside the Gregorian calendar) to date events in many Muslim countries. It is also used by Muslims to determine the proper days of Islamic holidays and rituals, such as the annual period of fasting and the proper time for the pilgrimage to Mecca.
Yuga There are four Yugas in one cycle:
Season As noted, a variety of dates are used in different countries to mark the changes of seasons, especially those that are calendar based. These observances are often declared "official" within their respective jurisdictions by the local or national media, even when the weather or climate is contradictory.[20] However they are mainly a matter of custom only, and have not generally been proclaimed by governments north or south of the equator for civil purposes.[21][22] The Met Office in the UK uses a three-month definition, e.g. declaring "spring" to be March, April, and May.[23] At least one researcher writing in the Bulletin of the American Meteorological Society compared various definitions to actual temperature changes, and recommended this three-month definition for general use in the United States.[24]
Julian calendar The Julian calendar has a regular year of 365 days divided into 12 months, as listed in the table below. A leap day is added to February every four years. The Julian year is, therefore, on average 365.25 days long. It was intended to approximate the tropical (solar) year. Although Greek astronomers had known, at least since Hipparchus, a century before the Julian reform, that the tropical year was slightly shorter than 365.25 days, the calendar did not compensate for this difference. As a result, the calendar year gains about three days every four centuries compared to observed equinox times and the seasons. This discrepancy was corrected by the Gregorian reform of 1582. The Gregorian calendar has the same months and month lengths as the Julian calendar, but, in the Gregorian calendar, years evenly divisible by 100 are not leap years, except that years evenly divisible by 400 remain leap years.[3] Consequently—since 16 February Julian/1 March 1900 Gregorian and until 15 February Julian/28 February 2100 Gregorian—the Julian calendar is currently 13 days behind the Gregorian calendar.
