Why is February the chosen month for leap year?

The Julian Calendar added a little more than 10 days to each year, making each month either 30 or 31 days long, except for February.

To eliminate this error, the Gregorian calendar stipulates that a year that is evenly divisible by 100 (for example, 1900) is a leap year only if it is also evenly divisible by 400.
