In my childhood memories, there is a catchy nursery rhyme that accompanied me to grow up: "One three five seven eighty wax, thirty-one days will never be bad; There are 30 days in 469 winter, only February 28, which is not a leap day in the fourth year, and must be added in February. "Whenever I hum this song softly, I always feel a wave of emotion for time.
This year is a leap year, which means that February, after a gap of four years, once again ushered in the 29th day. For most people, it may be just an ordinary day, but the knowledge of the calendar is interesting and there is a deep history and culture behind it.
The calendar mentioned here is the Gregorian calendar, also known as the Gregorian calendar, which is a calendar commonly used in all countries of the world today. Its origins can be traced back to ancient Rome and was created by Julius Julius Caesar of the Roman Empire. When the calendar is revised, the year is divided into 12 months. He set 31 days for odd-numbered months and 30 days for even-numbered months. This gives us 366 days in a year, about 1 4 days more than the actual solar year. To compensate for this discrepancy, Caesar decided to deduct one day from February, making February 29 days. Later, the Roman Emperor Augustus, in order to show his equal status with Caesar, also designated the month of August as the Great Month, changing it to 31 days. Because Caesar was born in July, and Augustus was born in August. Caesar was born in the 31-day month, and he changed the calendar to change the month of August to the great month. After that, put.
Nine, ten, ten.
January, December, and the month have changed. Unfortunately, the time was added and subtracted in February. Since February is the month of execution of prisoners in Rome, it is considered unlucky, so it is better to have a shorter day than a month. There is a leap year in four years, and February reverts to 29 days in leap years.
Every time February ushers in the 29th, I always feel the rush of time. This month seems to be shorter than the others, fleeting. But it is this short month that marks the end of a sixth of the new year. This can't help but remind me of the teachings of the ancients: "Persuade the king not to cherish the golden clothes, and persuade the king to cherish the youth." "Time flies like a white horse, youth is fleeting, I hope everyone will do it and cherish it.
