Answer :

On a leap year february is 29 days, assuming it's not however 
4*365 = 1460 days.
A regular year has 365 days. Every four years, a leap year begins, which has 366 days. If one of the four consecutive years is a leap year and the others are regular years, the expression is
x=3(365) + 366. 
x=1095+366
x=1461
There are 1462 days in four consecutive years.
