Is there a fixed formula for the division of the twenty-four solar terms in the compilation of Tongshu?

Yes Shu Tong is a philosophical work written by Zhou Dunyi, a Neo-Confucianism scholar in Song Dynasty, and later generations co-edited it as Zhou Ziquan's Book. 24 solar terms's exact time calculation formula: life span general formula -[y× d+c]-l, where Y= the last two digits of year, D=0.2422, L= leap year, and c depends on solar terms and year. Twenty-four solar terms refer to 24 specific festivals in the China lunar calendar that indicate seasonal changes.
