Is the winter solstice in 2004 2 1 or 22?

According to calculation, the exact time of the winter solstice in 2004 is 20: 42 on February 26th, 2004, 438+08.

The winter solstice in 2004 was one day earlier than in previous years. According to calendar experts at the Purple Mountain Observatory, this situation is not uncommon. Winter solstice is one of the 24 solar terms. Many people mistakenly think that the 24 solar terms are related to the lunar calendar. In fact, it belongs to the solar calendar, which is divided into 24 parts according to the time when the earth goes around the sun. Because the exact time required for the earth to make a revolution is 365.2422 days, any solar term will not be fixed on a certain day, but will swing back and forth for one day. In normal years, the winter solstice is usually on February 22nd, 65438, and it will be advanced to February 22nd of 2 1 year in leap years.
