How to calculate the delay?

It is necessary to calculate the entry time according to the almanac, and the relatively simple method is to use the four-word formula of "Summer Solstice Day Three Geng" to express the entry date.

This means that from summer to the third "more" day in the future, you will enter the dog days, start lodging 10 days, intermediate lodging 10 days or 20 days, and finally lodging 10 days.

In ancient China, the "chronology of trunk and branch" was popular, that is, 60 groups of different names matched with 10 trunk and 12 branch were used to record dates and recycle them. The day with the word "Geng" is called "Geng Day". The word "Geng" on Geng Day is the seventh word in 10 day of "A, B, C, D, E, Ji, G, Xin, Ren and Gui", which is repeated every 10 day.

Starting from the summer solstice, the third Geng day is the first Geng day, the fourth Geng day is in the middle, and the 1 th Geng day after beginning of autumn is the last Geng day. When there are four Geng days between the summer solstice and the beginning of autumn, the middle part is 10 days, and when there are five Geng days, the middle part is 20 days. Therefore, some years will have 30 days and some years will have 40 days.
