Near the New Year, many friends have found that the lunar Chinese New Year's Eve in 2022 is the 29th lunar month, not the 30th of the Waxing Moon as usual.

What is the reason for this?
1. The waxing moon is every 29, and the first month is 30
Lunar years are calculated according to the moon's profit and loss cycle changes, the 12th month of the lunar calendar in 2021 just ended on the 29th of the lunar calendar, according to the calculation law of the big and small months, naturally in the first month of 2022, there will be 30 days.
2. The influence of "Plastic Moon"
"Plastic Moon" is used to calculate the number of days in the month, "Plastic Moon" cycle is divided into 29 days and 19 hours and 29 days and 6 hours, so just divide the lunar month into 30 days of the big month and 29 days of the small month. The first month of 2022 just happens to belong to the big moon, which just makes the twenty-ninth lunar month of 2021 a Chinese New Year's Eve.
Chinese New Year's Eve is not unusual, for example, in 2003, 2006, 2013, 2016, it is the twenty-ninth night of the Waxing Moon, the Chinese New Year's Eve night, according to the Calculation of Pingrun Year, between 2025 and 2029, Chinese New Year's Eve will be absent.
