Daily trunk and branch calculation table of trunk and branch dates

Daily expenditure formula: Daily expenditure = number of years+number of months+date (minus 60 if the total is greater than 60; 65438+ 10 and February every day for one year)

The years of 65438+ 10 and February belong to the previous year and can be regarded as 65438+March and 65438+April of the previous year. For example, the number of years depends on 2065438+20 15 years1October 30th.

Example: Find the trunk and branch of1July 986 18, August 2000 15, June 20 17 respectively?

Solution: Looking up the table, we know that the year of 1986 =40, the year of 2000 = 54,201517, less than March, belongs to the year of 20 14 =7.

1986 July 18 = 1986+ July+18 =40+2+ 18=60= Guihai.

August 200015 = 2000+August+15 = 54+33+15 =102-60 = 42 = b.

2015 65438+1 October 7th = 20 14 years+1month +7 days =7+6+7=20= unfinished.
