Calculation method of non-Chen year

When the number of years in the Gregorian calendar is divided by more than 60 and 32, or the number of years is reduced by 3, the remainder divided by 10 is 9, and the remainder divided by 12 is 5, so that we can get the corresponding branches in the calendar, starting from beginning of spring. However, when the lunar calendar records the year by borrowing branches, the year from the first day of the first month of that year to New Year's Eve of the following year is "year". The trunk calendar and the lunar calendar are two different calendars. The two are different in the starting point of a year, the division rules of months and the number of days in a year. Please note that most online calendars start in beginning of spring, which is not a Chinese year, which is correct. This has been the common practice of officials and people for thousands of years. Only a few marks are improper, which needs attention.

In ancient times, the almanac was calculated and published by Qin, and it was not allowed to be reproduced without the approval of the royal family. It was not until the sixteenth year of Qing Qianlong that the people were allowed to engrave the official seal of the Yellow Calendar. When we open any imperial calendar, we can see that the change of the year of dry support is not on the first day of the first month, but on the day when the shadow is established in beginning of spring.
