The law of solar terms in the twenty-four solar terms of the lunar calendar
Y= year, D=0.2422, L= leap year, and C depends on solar terms and year.
In another case, if you know the exact time of a solar term in the previous year, you can easily calculate it from the ballads, and the next year is the time of the solar term. The rules of solar terms are as follows:
Beginning of spring 5 was knocked out at 3 o'clock and retreated at 3 o'clock.
At 1: 15, Changxia received the harvest at 9: 35.
The awn seeds are retired for two days, and the summer is asked at five o'clock on the third day.
Take a rest for three days in five days, and take a rest for one week in beginning of autumn Millennium for six days.
Six days plus six hours in cold dew, six days and seven o'clock tour in beginning of winter.
Snow was harvested from 4: 00 on the 6th to 9: 00 on the 5th.
explain
1. beginning of spring started at 3 o'clock on the 5th. If you want to know when beginning of spring is this year, you should know the time in beginning of spring last year. For example, I want to know the beginning of spring time of 1998. As long as you know the beginning of spring time of 1997, you can push it. 1997 beginning of spring time is1February 27th, 996 in Yin Shi. According to the Song formula, it takes five days and three hours. In 1997, the abortion was six days. (Because the abortion was in February 1996, but the 27th was handed over to beginning of spring, so this day is counted as 65438+February 27th,15th, 3:16th. Note: If there was a leap month last year, the actual start time of spring could be one month earlier. Actually, it was on the eighth day of the first month of 1998, and spring began.
2. As long as we know the beginning of spring time this year, we can launch the annual festival time. Take 98 as an example. In 1998, beginning of spring was on the eighth day of the first month. Then, as long as we walk back for three hours on the basis of beginning of spring Day in 1998, we can pay the festival at 8: 00 or 5: 00 in February 1998. (calendar on the eighth day of February)
3. On the basis of this beginning of spring time, one hour plus the number of abortions is Tomb-Sweeping Day. For example, in 1998, beginning of spring added an hour on the eighth day of the first month (it should be noted here that there were 1 abortion from beginning of spring to Tomb-Sweeping Day, so an extra day was needed), so the fourth day of 1998 was Tomb-Sweeping Day. (hand in the calendar at 9: 00 on the first day of March)
4. Assemble at 9: 30 in the long summer. Similarly, this year's beginning of spring is the foundation, plus nine hours and three hours, plus the number of abortions, it is the time of the Long Summer Festival (there are two abortions from beginning of spring to Long Summer, so it takes two more days), so the eighth day is twelve days and nineteen hours = eleven ugly days. (April 1 1 ugly day to long summer) (the actual calendar is April 10-ugly day on Sunday).
5. In the same way, this beginning of spring Day is based, plus two days reduced to one hour, plus two days in February and March, and twelve days on the eighth day: 12 Shi Mao, that is, 12 Shi Mao is given to Changxia. (The calendar will be delivered in Shi Mao on May 12).
6. Ming Xia seeks the same principle at five o'clock in the third grade. Beginning of spring Day, plus 3 days and 5 hours, plus the number of small months, is the holiday time in summer. The eighth day is 13 days, 5 hours 13 days = 14 days. (beginning of spring has three months of miscarriage in the summer vacation, so three days are added. ) So the leap of 1998 was in May of 14, when Xiao Shu handed over. (Submit the calendar on May 14)
7. Similarly, the five-day retreat to beginning of autumn Festival is based on beginning of spring Day, plus five days MINUS one hour, plus the number of small months, which is the holiday time in beginning of autumn. The first day of the eighth grade 15 days and 3 hours 14 days = 17 ugly days. There are four months from beginning of spring to beginning of autumn, so add four days. ) hand in the calendar on June 17.
8. In the same way, based on beginning of spring Day, plus six days MINUS one hour, plus the number of abortions, is the delivery time of the Millennium: 8 hours on the first day +6 days 1 hour 14 days = 18 Shi Mao (there were four miscarriages between beginning of spring and the Millennium, so four days were added), which is July 6598. (The calendar will last for two days, that is, March 18 in Yin Shi).
9. Six days plus six points in the cold dew, beginning of spring time plus six days and six hours, plus the number of small months in the middle, is the synchronization of cold dew, that is, 8 days and six hours 14 days = 18 days (there are four small months between beginning of spring and cold dew, so four days are added), that is, August 1998 18 days.
10. Similarly, beginning of winter started traveling at 7: 00 on the 6th. Beginning of spring time plus 6 days and 7 hours, plus the number of months in the middle, is the solar term in beginning of winter. On August 16th of the lunar calendar, at 7: 00, 15 days = 19. (Five days later because there are five hours between beginning of spring and beginning of winter. Therefore, in September 1998, in 19, Shihai was handed over to beginning of winter Festival. (The calendar will be handed over at midnight on September 19)
1 1. "Similarly, from 4 o'clock on the 6th to the snowy day, beginning of spring time plus 4 o'clock on 6 days, plus the number of months in the middle, is the delivery time on snowy days, that is, 8 days 16 days at 4 o'clock 15 days =19 (after 5 days, So 1998 10, 19 entered for the jiaotong university snow festival. (The calendar is due in 65438+ 10 month and 65438+September)
