Because this year is a leap month, there are two beginning of spring in the lunar calendar 1 year, so it is called the double spring year.

Introduction to leap year

The usual explanation is that there are many days, hours and minutes in a year, and there are still some left after taking the integer of 365 days. After accumulating to one day (24 hours), one more day is added, and the year with one more day is a leap year. This explanation just tells everyone how to calculate, which is artificially set.

The most fundamental reason is that the cycle of the earth's orbit around the sun is 365 days, 5 hours, 48 minutes and 46 seconds (365 days +09 days), which is the tropic of cancer. The Gregorian calendar has an average of only 365 days a year, which is about 0.2422 days shorter than the tropical year, and the remaining time is about one day every four years. Therefore, at the end of February of the fourth year, 1 day was added, so that the length of a year became 366 days, and this year was a leap year.
