In the minds of ancient Chinese, "Yuan" is the meaning of the beginning; "Dan" is the meaning of the morning. According to historical records, as a very important festival, in the history of China, "New Year's Day" has many titles, such as Yuanri, Yuanzheng, Yuanchen, Kainian, Yuanchun, Shangri, and Huanian, but in many titles. It is still said that "New Year's Day" is the most common and the longest time. The "yuan" of "New Year's Day" refers to the beginning, which is the first meaning. The beginning of the number is called "yuan"; "dan", pictograph, the "day" above represents the sun, and the "one" below represents the horizon. “Dan” means that Taiyuan Danyang rises from the horizon, symbolizing the beginning of the day. When people combine the words "yuan" and "dan", they are extended to the first day of the New Year. Due to the different longitudes and time of the countries in the world, the "New Year's Day" date is also different.
How was the date of New Year's Day established?
Many people know that the calendar that is now in use in China is the Gregorian calendar. After the Revolution of 1911 overthrew the Manchus, in order to "walk Xia Zheng, so when the farmer went down, from the Western calendar, to the statistics", the use of the AD method was determined as the official calendar of China, January 1st was the New Year's Day, and the first day of the lunar calendar was positioned. Spring Festival". After the founding of the Communist Party, it was basically used. The official calendar used the Gregorian calendar, and the festival adopted the lunar calendar—a system of dual calendars.

All calendars in the world are basically divided into two systems - the solar calendar and the lunar calendar.
I want to know why there are these two systems, we should first figure out a few concepts:
Returning to the Year - From the Earth's perspective, the time the sun reappears from the vernal equinox to the vernal equinox is 365 days, 5 hours, 48 minutes and 46 seconds.
Looking at the moon - from the earth, the time of the moon from one month to another is 29 days, 12 hours, 44 minutes and 2.8 seconds.
The moon revolution period - the exact time of the moon revolving around the earth, 27 days, 7 hours, 43 minutes, 11.559 seconds.
In the case of geostationary, the moon's revolution period is a little more than 27 days, but since the earth itself revolves around the sun, every round of the moon's surplus, plus the compensation time of the earth's revolution, this is a cycle of the lunar month. .
A cycle of the lunar month is mainly composed of the moon, the moon and the moon. When the moon phase returns to the moon, it is the beginning of a new month, and the Chinese lunar calendar becomes the "first day."
