Introduction of solar terms and years

Off-year is not a solar term, and the time of off-year varies from place to place. Details are as follows:

1. Different places have different concepts and dates. In China, it is generally the 23rd of the twelfth lunar month, the 23rd of the twelfth lunar month in the north and the 24th of the twelfth lunar month in the south. Some residents along the lake, such as Poyang Lake, keep the tradition of boating and observe it on the 25th day of the twelfth lunar month.

In Jiangsu, Zhejiang, Shanghai, Northeast Jiangxi and Taiwan Province Province, the day when the kitchen god is sacrificed on the 24th of the twelfth lunar month is called "kitchen sacrifice", and the day before New Year's Eve is called "Lunar New Year's Eve". Compared with Lunar New Year's Eve, both Lunar New Year's Eve and Lunar New Year's Eve refer to a whole day, not necessarily at night, and there is no such thing as Lunar New Year's Eve. Some ethnic minority areas in southwest and north China celebrate New Year's Eve. It is the 15th day of the first month in Nanjing and the 16th day in some parts of Yunnan.

2. According to the position change of the sun in a year and the evolution order of the ground climate caused by it, the ancients divided the 365 1/4 days of a year into 24 segments and 12 months to reflect the four seasons, temperature and phenology. This is the twenty-four solar terms. There are two sections every month. The first section is called "Festival" and the middle section is called "Qi".

The ancients divided a solar year into seasons, knots, qi and climate, 1 year =4 seasons = 12 knots = 12 qi =72 climate, which is the definition of seasons and climate. Twelve months, every month, a "festival" is set, with "qi" in the middle, just like twelve bamboo festivals, which are inflated in the middle. This is the origin of solar terms and the original intention of honesty and thrift.

24 solar terms is: beginning of spring, rainy, startled, vernal equinox, Qingming, Grain Rain, Changxia, Xiaoman, Mangzhong, Summer Solstice, Slight Summer, beginning of autumn, Early Summer, White Dew, Autumn Equinox, Cold Dew, Early Frost, beginning of winter, Light Snow, Heavy Snow, Winter Solstice, Slight Cold and Severe Cold.
