1st answer: Because Earth actually takes 365 days and 6 hours to complete its one revolution. So after four years 6 hours change into 24 hours [6*4], meaning 1 day which is added in February as 29th February.
2nd answer: February has 29 days in a leap year for the following reason: A normal year is actually 365 days around 6 hours to be exact 5 hours, 48 minutes and 47 seconds.
To make our calendar system work, we just lump the 6 hours together every 4 years to create the extra day in February, this just happens to be February 29th.
To mange the fact it's not exactly 6 hours for the extra, we adjust for that on the century.
You can use the following algorithm to work out if a year is a leap year or not:
if year is divisible by 400 thenis_leap_year else if year is divisible by 100 then not_leap_year else if year is divisible by 4 then is_leap_year else not_leap_yearIn a non-leap year February has 28 and in a leap year it has 29 days A non-leap year is like 2009,2010,2011,2013,2014,2015 A leap year is 2008, 2012, 2016 (every 4 years)
