Why 2021 is not the Spring Festival
2021 is not the Spring Festival, but the beginning of the Spring.The Spring Festival is a major festival every year.On the first day of the first month of the lunar calendar every year, because the Gregorian calendar year in 2021 is quite different from the lunar calendar year, the Gregorian calendar time for the Spring Festival in 2021 is often later than in previous years.
Time for the Spring Festival in 2021
The first day of the first month of the lunar calendar is the Spring Festival, commonly known as "Chinese New Year".The Spring Festival is the first day of the Lunar New Year.It is the most solemn traditional festival of the Chinese nation.It has a history of more than 4,000 years and started from the Yu and Shun period.Therefore, the Spring Festival time in 2021 is on February 12, 2021, Friday, which is the first day of the first month of the Xin Chou Year (Ox Year).In ancient folk, people started the "busy year" from the sacrificial stove on the 23rd or 24th of the year, and the new year did not end until the 19th day of the first lunar month.In modern times, people set the Spring Festival on the first day of the first lunar month, but generally it will not end until at least the fifteenth day of the first lunar month.
Why is the Spring Festival so late in 2021
The Spring Festival is fixed on the first day of the first month of the lunar calendar, but its date in the solar calendar is "erratic".Shi Zhicheng, a member of the Chinese Astronomical Society and director of the Tianjin Astronomical Society, said that in the solar calendar, the earth revolves around the sun once is a tropical year, with 365 days in a normal year and 366 days in a leap year.The traditional Chinese lunar calendar in my country is based on the cycle of the moon’s roundness and vacancy.A month is about 29.5306 days, and the accumulation of 12 synodic months is 354 or 355 days, which is about 11 days away from the tropical year, and the 3-year accumulation has exceeded one month.
If the number of days between the lunar calendar and the solar calendar is allowed to be so different, there will inevitably be a phenomenon that the Spring Festival will pass in the summer.In order to keep the time of the Spring Festival in the Gregorian calendar relatively stable, the adjustment method is to arrange 13 months in some years, and there are two same months, which need to be "intercalated".The rule of "setting intercalation" is based on the twenty-four solar terms.
If there is no leap month in the previous lunar year, the next year’s Spring Festival will come "early", otherwise, the Spring Festival will be "late".Since the upcoming Lunar New Year of the Pig is a normal year, the Spring Festival in 2020 will be "early".In the same way, the upcoming Lunar New Year of the Rat will have a "leap month", so the next Spring Festival in 2021 will be "late".
