Need to consider whether the year is a leap year. If it is a leap year, February is 29 days. Any year divisible by 4 is a leap year, and any year divisible by 4 is a flat year. For example, calculate the sun column 65438+February 65438+February 2020. First of all, we have to calculate the New Year's Day. 2020 is divisible by 4, which is a leap year, so our calculations are all calculated according to the leap year method.
(AD year-1) × 5+ (AD year-1) ÷ 4+ days in a year} ÷ 60. Take the obtained remainder ÷ 10, and take the obtained remainder as the heavenly stem ordinal number. Take the remainder ÷ 12, and the remainder is the ordinal number of the earth branch, which is the sun column.
The eight-character sun column refers to heavenly stems and earthly branches on the day of birth, which can also be said to be the fifth and sixth words in the birth. The eight characters are four groups of branches calculated according to the time of birth (year, month and day), namely, the annual column, the moon column, the sun column and the time column. So the eight characters are also called four pillars.
It should be noted that from the perspective of the horoscope, it is very important that the heavenly stems (Geng) of the Japanese column represent the life of the host, sometimes called Japanese yen and Japanese Lord, and the earthly branches of the Japanese column represent the life of the spouse.
Sun Zhu's modern view
In modern times, influenced by the western calendar, some numerologists have new views on the starting and ending points of the solar column. They think that a new day should not start with children, but should start with children. For example, Mr. Yuan Shushan, a famous numerologist in modern times, discussed this issue in his famous book The Origin of Numerology.
Yuan believes that the sun bar is still counted on the same day, but the time bar should be the child's time of the next day after the first child's time in the evening (because the time has been paid). Yuan's statement had a great influence in modern times, and it is still used by some numerologists.
But we read all the ancient books, not just the four-pillar numerology book, but all the ancient books such as Qimen, Bagua, Zihui and Liuren. But we can't find any such algorithm. It can be seen that the above views are only discussion nature, not conclusion.
