Delayed solar terms

This year's Year of the Ox lasts for 354 days from February/2002 12 to June/2022 1 day. The last year of the ox in 2009 and the next year of the ox in 2033 have 384 days. Obviously, the year of the ox just started is more than the previous year.

According to Cao, director of the Beijing Folk Museum, the difference in the number of days in the lunar calendar is due to the calculation of the calendar. We now have three calendars: the lunar calendar, the solar calendar and the yin and yang calendar. Among them, the solar calendar is a calendar based on the movement cycle of the earth around the sun, with 365.2422 days in a year; The lunar calendar is a calendar that changes according to the moon cycle, with 354.672 days in a year. Because there is a ten-day difference between the solar calendar and the lunar calendar, there is also a lunar calendar, which is familiar to everyone, involving leap months and non-leap months. According to the tradition of Yin and Yang, there is no leap month in normal years. This year's Year of the Ox is a normal year. There was a leap month in the last year of the ox and a leap month in the next year of the ox, so there is a difference of 30 days between this year and the next year of the ox.

Generally, there are 24 solar terms in a year, and there are 25 solar terms in a year with leap months. 202 1 Is it February 3rd or the Year of the Rat in beginning of spring, and wait for the next year?
