What year? What's the age?
Shuowen: "Bang, ancient Shu also. From the five grains, a thousand voices.
In the Spring and Autumn Period, it was said,' Big Chai.' "
As for "Chinese New Year", when did it begin? Opinions vary, and no one can agree. There is a saying that it started in ancient La Worship or Wax Festival, but the date is not fixed. Most scholars believe that 2008 really became a festival, which was roughly formed in the Han Dynasty.
What's the age?
Han Bangu's White Tiger: "If you are old, it will be 366 days a week. (According to: In ancient China, the age of one year was set at 366 days, but it was changed to 365 days and a quarter after actual measurement. See Historical Records and Almanac), everything is completed, so I am one year old. "
Zhou Li Chun Guan: "It is the year of the year, and there are orders."
Han Zheng Xuan's Note: "The middle number refers to the year, and the new number refers to the year. China and the new moon are not uniform in size, so they are leap. If today is a calendar day. "
Tang Kong Yingda's Book of Rites and the Moon Order is more specific about the years of middle and new numbers: "
The middle number is1a week in February, which is a quarter of 365 days, one year old.
The number of new moons is1February, and a week is 354 days, which is called a year.
This is a relative age, so there is a difference between the new number and the middle number. "
Especially the so-called
The "median age" refers to the solar year (that is, the time for the earth to orbit the sun once, which is exactly 5: 48: 46 in 365 days).
The "new moon year" refers to the lunar year. In fact, the lunar calendar in China is a combination of yin and yang-that is, the "dual track system" of lunar calendar and solar calendar is implemented in parallel.
"One week in mid-December" means that 24 solar terms (including 12 in mid-December) rotate for one week, and a quarter (day) of 365 days is exactly one year old (that is, a year in the Chinese solar calendar).
In the lunar calendar, a year is divided into twelve months on average (one month equals 29 days, 12: 44: 2.8, so a month in the lunar calendar is 29 days or 30 days).
There are only 354 or 355 days in a year; A leap year has thirteen months, a total of 383 days or 384 days. A flat year and a leap year are "adjusting seven leap years in nineteen years".
Therefore, in ancient times, the winter solstice was the "first year" and the first month was the "first year".
Because of this, there are still folk proverbs such as "fat in winter and thin in years" and "winter solstice is as big as years".
