Funny joke: Excuse me: Which month has 28 days?

Every time the earth revolves around the sun for 365 times, February is 28 days. 2. When there are not only 24 hours in a day, but 1 hour in 24 quarters, people have been accumulating 1 hour, and in the fourth year, there will be more 1 day. It was February 29th.

The current solar calendar was made by Julius Caesar of Rome in 46 BC. At first, he stipulated 12 months per year, 3 1 day per month and 30 days per month, so there are 366 days per year. But at that time, Rome executed a number of prisoners every February, so February was considered an unlucky month. As a result, Caesar reduced February by one day, leaving 29 days. Later, Caesar was killed by Augustus. He found that July when Caesar was born had 365,438+0 days, while August when he was born had only 30 days, so he subtracted one day from February and added it to August. So there are 28 days left in February, and it becomes 3 1 day in August. At the same time, he changed the number of days in the next few months and became like this. ? Four years is a leap year, but don't forget that there are four years in the solar calendar, that is to say, every four years is a leap year, and February of a leap year has 29 days!
