How Many Mondays in 2012
There are exactly 53 Mondays in the year 2012.
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 2012 has exactly 366 days.
Now if the year starts on a Monday in a non-leap year, you end up with 53 Mondays. Or if either of the first two days lands on a Monday during a leap year, then you can also get 53 Mondays. Check the calendars below for January and December of 2012 to see exactly where the year starts and ends.
