How Many Sundays in 2013
There are exactly 52 Sundays in the year 2013.
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 2013 has exactly 365 days.
Now if the year starts on a Sunday in a non-leap year, you end up with 53 Sundays. Or if either of the first two days lands on a Sunday during a leap year, then you can also get 53 Sundays. Check the calendars below for January and December of 2013 to see exactly where the year starts and ends.
