Extended data

There are big and small months in the solar calendar, that is, there is such a stipulation in the solar calendar months: "April, June, June and 1 1 have 30 days, and the rest months have 3 1 day, except February, with only 28 days."

The size of the moon began in Caesar's time in the Roman Empire. At that time, Caesar sent someone to revise the calendar and enacted the julian calendar Law, which stipulated that all the months with special religious significance were 365,438+0 days, and the unimportant months were 30 days. Therefore, the month of 1, March named after the God of War, and July named in honor of Julius Caesar all have 3 1 day. Because February is an unlucky month for executing prisoners, there are only 29 days.
