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

The lunar calendar is the lunar calendar, but the traditional solar calendar in China is the Gregorian calendar, which is internationally accepted. You don't need to count. 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, and each new moon is the first day. The full moon is 15 (the 16th month) and the dark month is 29 (the 30th month).

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

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 a normal year and a leap year, which makes the number of days in the tropic of cancer different from the actual number, and each year can be one day worse on the calendar. In this way, after the lunar calendar passes through any whole year (the number of months equivalent to the lunar calendar in a year is 365.2422/29.588 =12.36827 months), the solar calendar can be found on the current calendar. 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 alternation of yin and yang. For example, the first day of the fourth lunar month can be used as an independent variable, and the corresponding Gregorian calendar can be found on the 1995 calendar as April 30th. Because the number of months has been calculated, the mantissa (decimal) of the number of months that have passed is converted into whole days, and April 30th is added 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 searched is April 30th plus 0.64957×. In this way, the date conversion result of the given example is obtained ... ".64957 month origin,

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

It is understood that Yi Zegong 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 Lund, 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.

As 1 May 1999 1 day (including February of that year) falls on 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.

3. Correction of calculation results

In fact, there are often great errors when the Gregorian calendar above is converted into the lunar calendar. For example, the first day of April in Xining is Gregorian calendar 1070 May 13, not May 19. The results are corrected by using the branch counting method in China calendar.

For example, Ma Yize was born on March 20th, 3 10, and the * * * calendar days are from January New Year's Day to March 20th, and the * * * calendar days are 79 days.

From New Year's Day in January to New Year's Day in 309, there are 1 13 leap years and 196 normal years. The Gregorian calendar is July 16 in Gregorian calendar 622. It is known that the 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
