âºâº How many Saturdays are there in 2015? There are exactly 52 Saturdays in the year 2015. The answer to this question is not always simple. Most of the time, it will equal the number of weeks in a year, but that's only true for some of the days of the week. Most years have 365 days, but a leap year has 366 days. That adds up to 52 weeks (where each week is exactly 7 days) PLUS 1 or 2 additional days. The year 2015 has exactly 365 days. Now if the year starts on a Saturday in a non-leap year, you end up with 53 Saturdays. Or if either of the first two days lands on a Saturday during a leap year, then you can also get 53 Saturdays. Check the calendars below for January and December of 2015 to see exactly where the year starts and ends.
For example, the year of 2000 had 54 weeks. Its first week consisted of only one day which was Saturday, the 1st of January. And the last week of 2000 included just one day too. It was Sunday, the 31st of December. Conclusion From the point of view of mathematics, there are 52 1/7 (or 2/7) weeks in a year. It means 52 full weeks. But on the calendar there will be 53 or 54 separate weeks though one or two of them will be incomplete. So the answer to the question about the number of weeks in a year depends on what you prefer to call a week. If you mean seven days from Sunday till Saturday, then no year will have more than 52 weeks. But if a week for you is a separate line or column in the calendar, then there may be up to 54 weeks in a year.
