Question

Why did we decide to give February just 28 days when lots of other months have 31 days? Couldn’t we have just taken some of the 31st days from other months and added them to February?​

Answer 1

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.

In the past, a year had 355 days instead of 365 days.
