Easiest is probably a table:

Jan, Mar, May, Jul, Aug, Oct, Dec have 31 days.
Apr, Jun, Sep, Nov have 30 days.
Feb has 28 or 29 days. It has usually 28 days.

The exception is: in every year that is divisible by 4, Feb has 29 days.
The exception to the exception is: in every year that is divisible by 100,
Feb has 28 days.
The exception to the exception to the exception is: in every year that is
divisible by 400, Feb has 29 days.

Thus, until 2100, you don't need to worry - every year that is divisible by
4 (including 2000) is a leap year.
