"People who wrote' Wang' every month in the Spring and Autumn Period emphasized three corrections". What is three rectifications?

During the Spring and Autumn Period and the Warring States Period, there were so-called summer calendars, lunar calendars and weekly calendars. The main difference between these three calendars is the difference at the beginning of the year, so it is also called "three rectifications". The weekly calendar begins with the month when winter solstice usually occurs (that is, November in the summer calendar), the lunar calendar begins with the ugly month (that is, December in the summer calendar), and the summer calendar begins with the lunar month (that is, the first month in the lunar calendar). The weekly calendar is one month earlier than the lunar calendar and two months earlier than the summer calendar. Due to the different months of construction, the four seasons are also different.

On the other hand, it is said that there are: Tianzheng (lunar calendar 1 1 month, the founding month, winter to the sun and the moon) is the "minimum pole" month of solar rays (winter to the sun), and it will increase during the day from this month; The earth pair (65438+ lunar February, ugly month, cold month) is the "cold pole" of temperature. Since this month, the climate has become warmer, and people are right (the first month of the lunar calendar, the lunar calendar and the rainy month).
