Do you know how to calculate the lunar calendar according to the solar calendar?

The lunar calendar is the lunar calendar, but the traditional solar calendar in China is the Gregorian calendar, which is internationally recognized. You don't need to count it. You can find it on your calendar or mobile phone, and the lunar calendar will be marked next to the solar calendar!

1, solar calendar date calculation method of lunar calendar date:

As mentioned above, the date of the lunar calendar is based on the full moon, which takes each new moon as the first day, the full moon as the fifteenth day (the 16th day of the big month) and the dark month as the 29th day (the 30th day of the big month).

If you want to know what June 8th is, 1984? This formula can be used to calculate the lunar calendar date: let: the number of years-1977 (or 190 1)= 4q+R, then: lunar calendar date =14q+10.6 (r+/kloc-0.6). 4) Example:1May 7, 1994, the lunar calendar date is: 1994-1977 =17 = 4× 4+1so: Q = 4, r =/kloc-0.

2. Convert Gregorian calendar into lunar calendar

The position of the 24 solar terms on the ecliptic is fixed, but each year is divided into an average year and a leap year, which makes the number of days in the tropic year different from the actual number, and each year can be one day worse on the calendar. In this way, the solar calendar can be found on the current calendar after the lunar calendar has gone through any whole year (the number of months equivalent to the lunar calendar in a year is 365.2422/29.588 =12.36827 months). For example, you can first find the date of the solar calendar corresponding to the lunar calendar 1995, thus finding a temporary foothold, that is, finding the key to the exchange of Yin and Yang. For example, the first day of the fourth lunar month can be taken as an independent variable, and the corresponding Gregorian calendar can be found on the 1995 calendar as April 30th. Since the number of months has been calculated, the mantissa (decimal) of the number of months that have passed is converted into one day, and it is added to April 30th to get the date of the whole year that has passed (1995- 1070), that is, the date corresponding to the starting lunar calendar date, that is, the date to be checked is April 30th plus 0.64957×. In this way, the date conversion result of the given example is obtained ... ".0.64957 month origin,

(1995-1070) ×12.36827 =11440.6957.month.

It is understood that Yi Zehong was born in Liang Long on1June 2, 9221. According to the calendar months and days on the first day of each month in 1999 provided in the following table, we can calculate the calendar months and days on June 2, 20021day in Longde County and the calendar months and days on the first day of each month in 2099.

(2099-922) × 12.36827 = 1455.9987.

The remainder is 0.45379 months × 29.530588 days = = 13.4O days.

Since 1 May 1999 1 day (including February of that year) is June 19 of the Gregorian calendar, the calculation date of June 13 is June1day of the second year of Lund, that is, July 2 of that year and June 2 of that year/kloc.

3. Correction of calculation results

In fact, when converting the above Gregorian calendar into the lunar calendar, there are often great errors. For example, the first day of April in Xining is Gregorian calendar1May 070 13 instead of May 19. The results are corrected by using the method of counting days in China calendar.

For example, Maize was born on March 20th, 3 10, and the total calendar days from Muharran calendar are 79 days from Muharran New Year's Day to March 20th.

There are 1 13 leap years and 196 normal years from the first year of Muhalan to New Year's Day in 309. The Gregorian calendar is July 16 in the Gregorian calendar in 622. It is known that the ordinal number of branches on that day is 50, and the number of branches is reduced by 1 (counting from Jiazi), and the remaining 49 should be added to the following formula.

(309 × 354+ 1 13+79+49)÷60= 1827. 1 16667 0. 1 16667 ×60=7
