Calculating birthdays and dates of birth is divided into four steps.
Determination of year and month: the determination of year and month should be based on the change of solar terms, not solar and lunar calendars, but the time of festivals.
Year is the first day of the year from the Spring Festival, not from the first day of the first month, but from beginning of spring this year to beginning of spring next year.
1, annual column arrangement
Nianzhu is the first column of eight characters. Without it, there would be no month, day and time.
The boundary of a year is beginning of spring every year, the year before beginning of spring and the year after beginning of spring. The year column is determined by the perpetual calendar. For example, 1984 is the year of Jiazi, 200 1 is the year of Xinsi, and 2002 is the year of Renwu. Write the stems and branches of tea in front as the year column.
2. Monthly order plan
The determination of the monthly order is not based on the first day of each month, but on festivals as a sign to change the monthly order.
The solar terms of the monthly order are determined: beginning of spring in the first month; February shock; Qingming in March; Long summer in April; Mayawn seeds; June heat; Beginning of autumn in July; August white dew; Cold dew in September; Early winter in October; 1 1 monthly heavy snow; A slight cold in December. Enter the next month of the holiday date. The date can be either solar or lunar, depending on the month of birth.
The dryness of each month depends on different years, which can be found in the perpetual calendar. There are the following formulas to solve the problem of monthly dryness:
At the age of Aji, C was the first, and at the age of B Geng, E was the first.
At the age of Bingxin, he went to Geng, Ding and Yin.
If you ask where Wu Gui started, Jia Yin is a good pursuit.
The usage of this formula is in the year when Party A and Party B work respectively. The first month is the third month, such as Xu Jianian and the third month, and the rest are similar.
The formula on the back is skillful. Based on Gan Yang, A is turned into soil, raw Gan Yang is C. Ethyl heptyl alloy, and gold is dry. Bingxin is mixed with water, and the Yang that gives birth to water is Geng. Ding Renhe wood, wood is Ren. When fire is combined with fire, the yang of fire is a.
3. Layout of solar columns
For example, when searching the calendar on March 5th, 2002 (the lunar calendar), we found that Mao Yi was the sun pillar in the years of Renwu, Chen Jiayue and Mao Yiri.
4. Timing
Time is determined by the time represented by the previous twelve branches. In the morning and evening, the next day is after 23 o'clock. The formula for matching time with the sky is as follows:
A also needs a; Ethyl heptyl c for the first time.
Propane starts from e; Ding Ren Geng Zi Ju.
What is the prescription for fifteen? Lunzi is the true way.
