按照中国农历的纪年法,每个月都有两个节气，一年共有24个节气。
According to the Chinese lunar calendar, each month has two solar terms, and there are 24 solar terms in a year.
节气是中国农历特有的，中国古人在长期的生产劳动中，逐渐认识到地球绕太阳运行一周的时间是固定不变的365又1/4天，他们把它叫做”一年”，又根据太阳和地球的相互关系，把一年的天数分成24等分，用来表示季节和气候的变化。这样，每15天就有一个节气，每个月就有两个节气了。二十四节气在公历中的日期几乎是固定的，上半年（1~6月）的节气都在每个月的6日和21日前后；下半年（7~12月）的节气都在每个月的8日和23日前后。
The Chinese ancient people gradually realized that the earth’s orbit around the sun was a fixed 365 and 1/4 days during their long-term production work, which they called “one year”, and divided the number of days in a year into 24 equal parts according to the mutual relationship between the sun and the earth to express the seasons and climate changes. In this way, there is one festival in every 15 days, and two festivals in each month. The dates of the 24 solar terms are almost fixed in the Gregorian calendar, with the first half of the year (January to June) falling on or around the 6th and 21st of each month, and the second half (July to December) falling on or around the 8th and 23rd of each month.
