What is the earliest calendar that was included in the 24 solar terms in the history of China?

Tai Chi Calendar was drawn up by Zhao Xiahong and was used in the Western Han Dynasty (BC 156 ~ 87). This is the first time in the history of China that it has been included in the calendar of 24 solar terms, and 23 solar eclipse cycles have been introduced in 135 months. Taichu calendar was implemented from 104 BC to 85 AD. This year, Bian Qi, Li Fan and Jia Kui (30- 10 1) began to implement the four-season calendar based on the ancient four-season calendar in the Spring and Autumn Period. Li Fan, Jia Kui and Su Tong, another astronomer at that time, all realized that the moon moved at different speeds. Jia Kui also proposed that the movements of the sun and the moon should be calculated according to the ecliptic in the calendar. When Wang Mang was in power, Liu Xin made three calendars.
