I can tell you clearly that without checking the perpetual calendar, I am afraid that no master can immediately know the lunar date of a certain day. Why do I say this? Listen to me explain in detail. To know the lunar days, the principles and The calculation of horoscopes is similar. So here we will introduce how to calculate the horoscope of birth date from the Gregorian calendar birthday. The celestial stems and earthly branches of the birth year represent the best ones to find. Its year is the lunar year, from the first day of the lunar month to the New Year's Eve. Just check the almanac. You can also use the Sixty Years Table to back-reference. For example: in the year of 8, the heavenly stems are all Wu, in the year of 3, the heavenly stems are all Gui, and the earthly branches are counted with the thumb. For example, 1993 is the year of Guiyou in the lunar calendar. It is not difficult to calculate the celestial stems and earthly branches of the birth month. In the lunar calendar, November is the Zi month, December is the Chou month, and January is the Yin month. The following are the Mao month of February, the Chen month of March, the Si month of April, the noon month of May, the Wei month of June, and the seventh month. Yueshen month, You month in August, Shu month in September, and Hai month in October. But what the fortune teller calls December is different, it is marked by the twenty-four solar terms. Every year, the day from the beginning of spring to the day of Jingsheng is January, that is, the Yin month, the time from Jingsheng to Qingming is the February Mao month, the Qingming day to the Beginning of Summer is the March month, the Beginning of Summer to the Grain Grain is the April Si month, and the Grain Grain to the Minor Heat is the May month. In the midday month, the mild summer to the beginning of autumn is the last month of June, the beginning of autumn to the white dew is the shen month of July, the white dew to the cold dew is the unitary month of August, the cold dew to the beginning of winter is the ninth month, the beginning of winter solstice and the heavy snow are the tenth month, and the heavy snow solstice is the ninth month. Xiaohan is the twelfth lunar month, and Xiaohan to the beginning of spring is the twelfth lunar month. In this way, as long as you know the lunar month of your birthday, you will know the earthly branch of the birth month. What to do with the Heavenly Stem of the birth month? There is a table here. The first row is the celestial stems of each year, and the vertical columns are the earthly branches of each month. The celestial stems of each month are listed in the table: Moon A Ji Yi Geng Bing Xin Ding Ren Wu Gui Year Yin Yi Bing Yin Wu Yin Geng Yin Ren Yin Jiayin Mao Er Ding Mao Ji Mao Ji Wei Shen Qi Ren Shen Jia Shen Bing Shen Wu Shen Geng Shen You eight Gui Youyi Yi You Ding You Ji You Xin You Shu Ji Ji You Bing Shu Wu Shu Geng Shu Ren Shu Hai Ten Yi Hai Ding Hai Ji Hai Xin Hai Gui Hai Zi Eleven Wu Zi Bing Zi Geng Zi Renzi Jiazi Chou Twelve Ding Chou Ji Chou Xin Chou Gui Chou Y Chou For example, in the Jiazi year, Jiayin year and other years with A as the heavenly stem, the heavenly stem of January is C, which is Bingyin month, and February is Dingmao month. , etc., and the heavenly stems of the month of Jisi, Jimao, etc. are also the same as the year of Jiatianxia. . The calculation of the heavenly stems and earthly branches of the birthday is very complicated. It was determined by ancient fortune-tellers who determined the stems and branches of a certain day and then pushed them down one by one. To know the stems and branches of your birthday, you can only look up the perpetual calendar, and it is a perpetual calendar that compares the lunar and solar calendars. If you don’t know the lunar calendar date of your birthday, you can check the perpetual calendar. The daily stem and branch on the twenty-seventh day of the Yi Mao month (February) of the Guiyou year is Jihai. The stem and branch at the time of birth can be derived from the stem and branch at the birthday. In ancient times, a day was divided into twelve hours, corresponding to the twelve earthly branches. It happens that now two hours are one hour. Late at night from 23 o'clock to 1 o'clock in the morning is Zi time, from 1 o'clock to 3 o'clock is Chou time, from 3 o'clock to 5 o'clock is Yin time, from 11 o'clock to 13 o'clock is noon time, from 13 o'clock to 15 o'clock is Wei time, and from 15 o'clock to 17 o'clock is Shen Shi, 17:00 to 19:00 is Unity Time, 19:00 to 21:00 is Guard Time, and 21:00 to 23:00 is Hai Shi. These are the earthly branches during birth. The Heavenly Stem at birth is calculated from the Heavenly Stem at birth. There is a formula as follows: Jia and Ji add Jia, Yi, Geng, and B are at the beginning, Bing and Xin are from Wuzi, Ding, Ren, and Gengzi are at home, Wugui is pushing Renzi, and the time element is determined. This formula is used to calculate the heavenly stems when counting. That is to say, on any birthday, the heavenly stem is A or Ji, Zi hour is the Jiazi hour, B and Geng are the days of the heavenly stem, Zi hour is the day of Bingzi, Bing and Xin are the days of the heavenly stem, Zi hour is the Wuzi hour, Ding and Ren are the days of the heavenly stem. The day of the Heavenly Stem is the time of Gengzi. The days of Wu and Gui are the days of the Heavenly Stem. The time of Zi is the hour of Renzi. After knowing the heavenly stems of Zi Shi, the other seasons can be deduced according to the Sixty Years Table and so on. For example, the Zi hour of this day is Gengzi, then Chou hour is Xin Chou hour, Yin hour is Ren Yin hour, and so on.
The hour stem and branch at 8 o'clock on Jihai day (Chen hour) is Wuchen. If you insist on seeing the present seriously and are not confused, you should also understand the answer to the question!
