How to calculate 355 days in 2022?

China calendar is divided into lunar calendar, solar calendar and yin-yang calendar. The lunar calendar is based on the period of revolution of the moon, while the solar calendar is based on the period of revolution of the earth around the sun, so the number of days in each year is different. Generally, there are 354 or 355 days in the lunar calendar and 365 or 366 days in the solar calendar.

A year with a leap month is called a leap year, usually with 384 or 385 days, and a year without a leap month is called a normal year, usually with 354 or 355 days. So the Year of the Tiger is a normal year with 355 days. At the same time, a leap month will be added every two or three years to make adjustments. In other words, in 2022, the 10 day of the young tiger will be made up in the next leap year of the yellow calendar.

There is no New Year's Eve in 2022.

According to astronomical experts, this is mainly related to "looking at the moon". The traditional calendar is calculated by the "period of the first lunar month", which is determined by the movement periods of the moon and the sun. The "new moon" day refers to the first day, people can't see the moon, and the "hope" day refers to the fifteenth day, people can see the full moon.

Because the relative motion between the moon, the earth and the sun is not constant, the phase change period of a month is about 29.5 days, so the "first month period" is long and short, which leads to the phenomenon that there is a 30-day moon and a 29-day moon in a year in the yellow calendar. 2022 coincides with the twelfth lunar month, so there is no "New Year's Eve".
