Question

why does February have only 28 days? What is leap year?​

Answer 1

Answer:

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 account for the entire 365.25 day-long year, one day was added to February every four years, now known as a “leap year.” During most years, this left February with just 28 days.

Answer 2

Answer:

Because Romans believed even numbers to be unlucky, each month had an odd number of days, which alternated between 29 and 31. But, in order to reach 355 days, one month had to be an even number. February was chosen to be the unlucky month with 28 days.

LEAP YEAR:

a year, occurring once every four years, which has 366 days including 29 February as an intercalary day.
