Although the "Twelve Calendars of Qi" was not implemented, it had a certain impact on later generations-some folk activities took beginning of spring, Jing, Zhe, Han Xiao as the first day of the first month, and the twelfth month of February as the second day of the first month.
One thing needs to be explained: from the birth of the summer calendar (lunar calendar) to the present, the first day of the first month and beginning of spring are not the same day (except that it happens to be the same year), and it is not a historical reason to separate them!
