Sun-bead formula:? Daily stem ordinal number = years+months+date? (If the total is greater than 60, subtract 60. October and February of 65438+)
Description of monthly statement: 65438+ 10 and February are merged into the previous year, and 65438+ 10 can be regarded as 65438+ March of the previous year, and February is 65438+ April of the previous year, and 65438+ 10 and February are still used in the previous year. Set March as the first month of every year. Scope of application: March this year-February next year.
Extended data
Principle: the number of years is the daily branch ordinal number at the end of February this year, that is, the last day of the end of February, that is, February 28 in a normal year or February 29 in a leap year. For example, the year of 20 16 = 18 means the end of February 20 16 (February 29, 20 16) = 18= Xin Si. 20 17 year = 2065438+end of February 2007 = 2065438+February 28, 2007 =23= Xu Bing.
Because there are 365 days in a normal year and 366 days in a leap year, the number of years in the next year needs to be 5 or 6 days earlier than that of the current year. If the next year is a normal year, the number of years will be increased by 5(365-60*6=365-360=5 days), and if the next year is a leap year, it will be increased by 6 (366).
Average years = last year+5; Number of leap years = number of previous years +6.
