What is the lunar calendar in China?

A calendar in China, which is a kind of lunar calendar, is generally called lunar calendar. Normal year 12 months, 30 days in the big month, 29 days in the small month, and 354 or 355 days in the whole year (which month is big and which month is small in a year, which varies from year to year). Because the number of days in each year is about eleven days worse than that in the solar year, there are seven leap months in nineteen years, and there are 383 or 384 days in a year with leap months. According to the position of the sun, a solar year is divided into 24 solar terms to facilitate agricultural planting and other activities. The chronology is matched with heavenly stems and earthly branches, with a period of 60 years. According to legend, this calendar originated in the Xia Dynasty, so it is also called the Xia calendar. Also known as the old calendar and the lunar calendar.

The first month of the lunar calendar is customarily called the first month. November and December of the lunar calendar are called winter and twelfth months respectively, and now winter months are rarely used. This is the origin of the idiom "December in October", which literally means that October, November and December are the coldest months of the year.

The first ten days of a lunar month are customarily called the first day in the sequence, such as the second day of January in the lunar calendar. The last ten days are customarily called 20th in sequence, and some of them are called anniversaries. For example, the 22nd day of 1 month in the lunar calendar is called the 22nd day of the first month or the 2nd day of the first month.

Every month of the lunar calendar has a different nickname. Because of its close connection with agricultural production, plants are almost always used to represent it from February to September. The following are the nicknames for December of the lunar calendar:

[Edit this paragraph] Origin of solar terms

Twenty-four solar terms originated in the Yellow River Basin. As early as the Spring and Autumn Period, four solar terms were set, namely, mid-spring, mid-summer, mid-autumn and mid-winter. After continuous improvement and perfection, by the Qin and Han Dynasties, the 24 solar terms had been completely established. In BC 104, the taichu calendar written by Deng Ping officially set 24 solar terms in the calendar, and defined the astronomical position of the 24 solar terms.

The time when the sun runs along the longitude of the Yellow River from zero 15 degrees is called "a solar term". It runs 360 degrees every year, and * * * experiences 24 solar terms, twice a month. Among them, the first solar term of each month is "solar term", that is, beginning of spring, Jingzhe, Qingming, Changxia, Mangzhong, Xiaoshu, beginning of autumn, Bailu, Hanlu, beginning of winter, Heavy Snow, Xiaohan, etc. 12 solar terms; The second solar term of each month is "Zhongqi", that is, there are 12 solar terms such as rain, vernal equinox, Grain Rain, Xiaoman, summer solstice, great heat, intense heat, autumnal equinox, first frost, light snow, winter solstice and great cold. "Solar term" and "neutral qi" appear alternately, each lasting 15 days. Now people have called "solar terms" and "neutral gas" solar terms.

Twenty-four solar terms reflect the apparent movement of the sun in one year, so the dates of solar terms are basically fixed in the current Gregorian calendar, with the first half of the year being 6 days and 2 1, and the second half being 8 days and 23 days, with a difference of 1 ~ 2 days. Determination of year

1864 1.00 is the year of the lunar calendar, so 1864 is subtracted from this year, and the remainder divided by 10 is the heavenly stems, and the remainder divided by 12 is the earthly branches of this year. The corresponding heavenly stems and earthly branches is as follows.
