Among the 24 solar terms, which is festival and which is qi?

Twenty-four solar terms were also used by the ancients to match the architecture in December, that is, the zodiac months were arranged in turn by festivals.

Because December is a festival, not a festival, and its order is fixed.

For example, in the first month in silver moon, the first festival is beginning of spring, and the rain is neutral, which means silver moon and Tiger Moon. Of the 24 solar terms, every two are a pair, the first is harmony, and the second is qi. When we say month, it starts from the solar term, and the gas is included in the next solar term, ending last month and starting next month. For example, the second festival is scary, the vernal equinox is neutral, and next month is to establish Uzuki as the Rabbit Month.

Therefore, when a pair of solar terms (season and gas) ends, the previous month ends and the next month (solar terms) begins.
