Why is New Year’s Eve in 2022 not New Year’s Eve？ What is the difference between New Year’s Eve and New Year’s Eve

The Spring Festival in 2022 has no 30th anniversary. Why? Astronomical experts explained that the moon in the Chinese lunar calendar is arranged according to the cycle of the moon’s ups and downs, which is called "Shuowangyue". The average length of a lunar month is 29 days, 12 hours and 44 minutes (29.5306 days), which is not an integer, and the number of days in a month should be expressed in integers, so sometimes it is a small month, 29 days, and sometimes it is a big month and 30 days. At the same time, in order to ensure that the first day of each lunar month must be the new moon, the arrangement of the big and small months is not fixed, which needs to be determined through scientific calculation. So, how to determine how many days there are in a month? Astronomers regularly arrange the first day of each month in the lunar calendar on the day of the new moon, so that the number of days between two new moons is determined.

What is the difference between New Year’s Eve and New Year’s Eve?

First, the name is different.

Second, in the year when there is no twelfth lunar month, New Year’s Eve is the night of the twenty-ninth twelfth lunar month.

Third, to be exact, New Year’s Eve is the night before New Year’s Day.

Why is New Year’s Eve not on New Year’s Eve in some years?

At present, China uses two calendars at the same time. One is the Gregorian calendar, which is commonly used in the west, with 31 days in the big month and 30 days in the small month. There is also a lunar calendar or lunar calendar, which is arranged according to the cycle of the moon’s ups and downs in ancient China, and is called the "Shuowangyue". When the moon is full, it is fifteen, and when the moon is not visible, it is called the first day. However, the average length of a lunar month is about 29.5 days, which is not an integer, and the number of days in a month must be expressed in integers, so sometimes it is 29 days in a small month; Sometimes it’s a big month for 30 days. It’s normal not to be "30".

"From the perspective of the lunar calendar, although most of the time it is the Spring Festival on New Year’s Eve, it is actually normal not to be on New Year’s Eve until the 29 th." Wang Sichao told reporters. It is understood that there was no 30th anniversary before the Spring Festival in 2000, 2001, 2003 and 2006. It is understood that not only the Spring Festival in 2012 (the Year of the Loong), but also there is no 30th anniversary before the Spring Festival in 2013 (year of the snake). Some experts believe that it doesn’t matter whether the Chinese New Year is "30". "People often refer to ‘ New Year’s Eve ’ And ‘ New Year’s Eve ’ As the same day, in fact, the exact meaning of New Year’s Eve is the last day of the lunar year. Astronomically speaking, New Year’s Eve may be the 29th or 30th of the twelfth lunar month.
