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.
In any given year, there are 260 or 261 days in the year excluding weekends. This varies due to the fact that leap years have an extra day.
