How many days are in four consecutive years

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.
