February 9 this year will be the last Chinese New Year's Eve in recent years. After 5 years, there is no Chinese New Year's Eve, why from 2025 to 2029, the Chinese New Year's Eve for five consecutive years is "New Year's Eve".
To answer this question, we must first understand the structure of the Chinese lunar calendar. In our lunar calendar, the division of months is not arbitrary, but follows the waxing cycle of the moon. This is known as the "synodic month" and its average length is about 2953 days. However, here's a key point: this average number of days is not a whole number. This leads to the problem that when defining the number of days in a month, we have to use whole numbers. Therefore, in order to adapt to the cycle of the moon, our lunar month is sometimes 29 days, i.e., small moons;Sometimes it is 30 days, i.e. the big moon.
As the last month of the lunar calendar, it is not uncommon for it to encounter small moons. In fact, in the past few years, we have experienced several Chinese New Year's Eves without Chinese New Year's Eve. This is the case, for example, in 2013, 2016, 2022, and for 5 consecutive years from 2025 to 2029. This is due to this characteristic of the lunar calendar. Start planning for my 2024
