The 24 Solar Fortnights – ershisi jieqi – recorded session December 2021


Recording of the session that took place on 4 December 2021

Every month, we discuss the two solar fortnights of that month, looking at the meaning, the suggested actions to be in tune with that quality of qi, and the relevant acupuncture channels.


The 24 solar fortnights, ershisi jieqi 二十四節氣, are loosely based on the monthly ordinances, yueling 月令, first described in the Book of Rites, Liji 禮記 which corresponds to the astronomy of approximately 620 BCE. The twenty- four solar fortnights in total are 360 days, and this is break down of the effect of the sun’s heat on earth over the course of a year, a giant circle of 360 degrees. One complete cycle of the earth around the sun is one year, 360 in days and degrees, time and space. Tracing the cycle of the sun, taiyang 太陽, and its effect on humans, is to follow the cycle of the seasons, to maintain optimal health.  

春生, 夏長, 秋收, 冬藏, 是氣之常也, 人亦應之
Spring engenders, summer flourishes, autumn harvests and winter stores. 
This is the constant of qi and humans also resonate with it. Lingshu 44  

This agricultural calendar has been in use for millenia and includes a variety of festivals and special events. The twenty-four solar nodes each describe the specific qualities of the breaths/qi of Heaven and Earth (changes in climate, natural phenomena, farming) which are reflected in the human body.  

Every month, we will discuss the two of the 24 solar fortnights of that month, looking at the meaning of the terms, what were the suggested actions to be in tune with that quality of qi, including food, exercises, and the relevant acupuncture channels. By following the jieqi 節氣, we align ourselves with the cosmic energies and so can be more effective in our own life and in our ability to help our patients.
