How did the eight-character day come out?
I'll think about it and tell you some methods for your reference.
Finding the branch of the sun and the branch of the sun by the method of the solar calendar and the lunar calendar
Take Jiazi as 1, 1 and find the Japanese branch method.
Heavenly stem count: a1b2c3d4e56g 7n8n9decyl 10(0)
Number of branches: Zi 1 Ugly 2 Yin 3 Mao 4 Chen 5 Si 6 Wu 7 Fei 8 Shen 9 You 10
⅟ 1 1H 12 (0)
Calculation formula: (AD year-1) × 5+ (AD year-1)÷4+ days of the current year ÷60, with the remainder ÷ 10 as the heavenly stem ordinal number; Take the obtained remainder ÷ 12 as the ordinal number of the earthly branch.
In addition, whether it is a leap year should be considered when adding the number of days in the current year. If February is a leap year, it is 29 days.
For example, on March 1 day, 2008, the calculation of main branches is as follows:
(2008- 1)×5+(2008- 1)÷4+6 1÷60
(1 October 65438+3 1 day, February 29th, March1day * * * 6 1 day)
= (10035+50 1 (integer) +6 1) ÷ 60
= 176……37
Seeking heavenly stem: 37 ÷ 10 = 3 ... Article 7 (g)
Seeking ground support: 37 ÷ 12 = 3... 1 (son)
So in March 2008 1, the main branch was boxer.
This method can also divide the number of days in the current year by 60 to get the remainder, and then use it as the base of 2008. Then divide the radix by the number of days in the current year and divide it by 60. The algorithm is the same as before. For example, (10035+501) ÷ 60 =175, with the remainder 36 as the base, (36+6 1) ÷ 60 = 1...37, and the remaining 37.
Second, the number of dry branches on the day of the Spring Festival is 1, and the number of dry branches on the day of the lunar calendar is found.
This requires knowing the branches and branches of the Spring Festival, as well as the size of branches and branches in each month of that year (30 days in the first month, 29 days in February and leap month), in order to get the number of days in that year.
For example, on the second day of the second lunar month in 2008, the trunk and branch are calculated as follows:
Ding Chou, the main branch of the Spring Festival in 2008, took them as 1. 30 days in the first month, only 2 days in February, a * * * 32 days.
Seeking heavenly stems: 32 ÷ 10 = 3...2 (the remainder is 1 in D, so 2 is E).
Found the earthly branch: 32 ÷ 12 = 2...8 (the remainder is ugly as 1, and that 8 is Shen).
That is to say: the remainder of the number of days in the current year ÷ 10 is dry.
The remainder of the number of days in the current year ÷ 12 is a branch.
In 2008, the second main branch of the second lunar month was Wushen.
(If the remainder is greater than 60, divide by 60 to get the remainder, and then divide by 10 and 12 respectively. )
Several methods of calculating Gregorian calendar date
Diagnosis of hand, face and tongue 2009-08-06 16:42 Read 72 comments 0 font size: large, medium and small.
First, the prerequisite of palm method
1 You must know what New Year's Day is every year;
2. Grasp the ground and set the position of New Year's Day (called standard);
3. The bid starts in January, the palace in February, and then the bid starts in March, and the desired month is repeatedly typed, so this position is the 1 branch of that month;
4, every big month, forward 1, two big months forward 2 ....., as many big months as possible. You don't have to move every little moon. Only February is special. Two places will be retired on the 28th, and 1 place will be retired on the 29th.
5. After finding the number 1 of the current month, you can quickly push out the daily branches of the current month.
For example, it was checked on May 4th. 1999:
(1) Make it clear that New Year's Day on 1999 is a day of shame and ugliness (remember this day and don't look it up in the future).
(2) The ugly position under the finger root of the left palm is defined as 1 month from New Year's Day, the ring finger ends in February, returns to the middle finger root in March, returns to the ring finger tip in April and returns to the middle finger root in May. Then Guichou is tentatively set as the main branch of May 1, but after two big months of May 1 and three special months of February 1, there is no need to shift back and forth, so Guichou is the actual main branch of May 1. Counting from 1 forward to 4 is Chen Bing Day.
(3) If you want to push back the main branch Z 1 in May, you only need to put a Guihai Day 1 1 and a Gui You Day 2 1.
For example, the main branch was pushed on March 12, 2000,
(1) First find out the trunk and branches of New Year's Day in 2000. 1999 New Year's Day began to be ugly from the ugly position of the ground branch palm, and then from the side to the middle finger, it was the Wuwu, the main branch of New Year's Day in 2000 (if the leap year passed, it was counted as six).
(2) According to the previous method, there are 1 big month and a special February 29th day in the middle of 1 month, February Wuzi and March Wuwu, so Wuwu is the main branch of March 1, and the next one is March1/kloc-.
According to this method, as long as you remember the dry branches on New Year's Day of a certain year (as long as you memorize the "golden tongs for dry branches and solar terms"), you can quickly calculate the dry branches on any day in previous years.
B, mental arithmetic auspicious day perception method
If you want to calculate the calendar day of any day in your mind according to the Gregorian calendar, you only need to multiply the Gregorian calendar years by 5, add the Gregorian calendar years divided by 4, add 9, add the date, and add the months that have passed, and the number is the serial number of the main branch. If the months are even, the interval is 30 days. If this method is used, the starting point of the current year is March 1, the date is before March 1, and the year number is one year or more. The Gregorian calendar begins in March. They are 3, 5, 7, 8, 10, 12, 1.
The so-called branch number is the order of 60 flowers, such as 1 for Jia, 2 for Ugly B, 3 for Bingyin until 59, and 60 for Guihai. In use, it can be remembered that Jiazi is 1, JOE is 1 1, Shen Jia is 2 1, Wu Jia is 3 1, Chen Jia is 4 1, and Jiayin is 5 1. So, in this order, it will be
Multiplied by five and divided by four plus nine days, the interval between two months is thirty days.
3578 ten tail, this is a clever way to remember.
Example 1, 1 949 1 01,year number 49X5=245, after deducting multiple of 60, the remainder is 5,49/4 =12, and the constant is 9,000.
Example 2,1965438+May 4, 2009, the year number is 19X5= 95, after deducting the multiple of 6O, the remainder is 35, 19/4 = 4, the constant is 9, the date is 4, and it only occurs in March, and the month is.
Example 3,1February 27, 964, the date of C is March 27, with 63 years, and 63X5=3 15. After deducting the multiple of 60, the remaining 15, 63/4= 15, the constant is 9, and the date is 27, * * meets the seven major problems. If15+15+9+27+7-30 = 43, then 1964 is the third afternoon.
Finally, when this method is used in the next century, IO0 will be added to the year number, such as 2000 10O, 20 1 13.
It is very good to have a solar calendar date to launch the main branch of the sun, which is the best method I have found so far.
I haven't fully worked out this formula, but it's time for my plenary session.
The specific formula is as follows: [Three digits after the year are multiplied by 5+ three digits after the year divided by 4+9+ solar calendar days+month (0) bimonthly (30)+ monthly adjustment ]/60 = the remaining digits are taken as heavenly stems, and the remaining digits are divided by 12 to take earthly branches.
Monthly adjustment number (1 is one, four and five), (2 is two, six and seven), (0 is three) (3 is eight), (4 is nine and ten) and (5 is eleven and twelve).
But in leap years, that is, January and February, you have to subtract 1 and then calculate the number of branches.
The first method to calculate the stems and branches of heliostats is the formula method. Remember the following formula: 1.5 minus 1, 2.6 plus 0.6; Three MINUS two plus one, four MINUS one plus five; Seven zero nine plus two, eight plus one seven go; Ten plus twenty-eight, three wax three nine in winter; It will start running in March, and one will be added to the rest. The specific usage is as follows: Remember the number of Jiazi (trunk) on New Year's Day, which is 1 to 10 for Tiangan Jia Gui and 1 to 12 for Dizhi Jiahai. Now, according to the oral decision, the trunk of any day counts. Examples are as follows: For example, calculate the trunk and branch of 65438+February 3, 20051. On New Year's Day this year, Jia Zi is B unitary, B number is 2, unitary number is 10, and 12 is the wax in oral decision. The number of branches and branches of Dongyi 12 should be increased by 3 and 9 respectively, and the rest of the oral decisions should be analogized. Remember that it is calculated according to the Gregorian calendar. The specific algorithm is the sum of the number of branches on New Year's Day and the number of days in this month. For example, in this example, the monthly dry number of 65438+ February is: 2+3+31= 36,36/10 = 3, 6 is its own number, and the number of branches is:10+9+3/kloc-.
The second method is to find the total number of days, that is, to find the total number of days from New Year's Day to New Year's Day, and then divide by the turnover number of stems or branches to get the remainder of stems or branches, and then divide by 65438 in the order of stems or branches. For example, 65438+February 3 1 is 365 days from New Year's Day (plus one day every year). Heavenly stems rank five in the order of B, C, D, E and self, five for self-seeking, five for earthly branches, five for ugliness, and all roads lead to the same goal.
C, mental arithmetic daily branch and simple method of branch
Remember the Jiazi number constant of that year first.
The so-called "Jiazi Chang" is the number of days from the first Jiazi Day to the year. For example, 1998 65438+ 10/7 is my first Jiazi Day. 1998 jiazi constant is16; 199965438+1October 12 is the first Jiazi day, so the Jiazi constant of1999 is 1 1, and so on.
Second, calculate the total number of days in a day.
It should be noted that the seven months of 1, 3, 5, 7, 8, 10 and 12 are 3 1 day. April, June, September165438+1October, these four months are 30 days. In February, there are 28 days in a normal year and 29 days in a leap year (if the Gregorian calendar year is divisible by 4, it is a leap year; If it is a leap year, it must be divisible by 400). For example, 1 The total number of days on August 5th, 998 is1,with an average of 4 months on March 5th and July, 4 months on April 6th and 28 days on February * * * 365438+.
Third, find the serial number of Jiazi that day.
Jiazi serial number = total days in a day-Jiazi constant (if the difference is greater than 60, subtract 60 or multiples of 60 and take the remainder), such as Jiazi serial number1August 5, 998; 2 17- 16-60 x3 = 2 1
Fourth, calculate the main branch of the day.
Just remember the serial numbers of Jiazi 1, Jiashu 1 1, Shen Jia 2 1, Wu Jia 3 1, Chen Jia 4 1 and Jiayin 5 1. 1August 5, 998, the serial number of Jiazi was 2 1, so the Japanese branch was Shen Jia.
Five, about the total number of days does not exceed 60 days.
If the total number of days is less than 60, the main branch serial number =60- A constant+total number of days.
If you want to find the main branch of1June 65438+1October 1 1. 1998 jiazi constant is16; The total days of 65438+ 10 month 1 1 are11; The ordinal number of Jiazi on that day = 60-16+11= 55; The main branch of this day is Wuwu.
The advantage of this method is that you only need to remember one Jiazi constant every year, which is simple and fast, and you can calculate the branches and branches of a day at will when making gossip prediction. As for the annual Jiazi constant (one can be calculated by looking at the perpetual calendar, and the other can be calculated by the "dry-supported golden clamp formula"-that is, it is very simple and convenient to check it once a year.
