It begins with a full moon, then the moon is in the middle of the lunar month is full moon, the moon wanes and begins a new lunar month. There is a lunar calendar, which is easy to know what lunar day falls on a specific number. But if the lunar calendar for the desired year is not at hand, it is possible to make calculations on their own.

Instruction

To calculate the lunar day for a specific number, you need to know:
D – day of month
M – the ordinal number of the month

D = 2
M= 3
Y =2020

To find out the lunar day, you will need to calculate the so-called lunar year number. Each year is a lunar number, for example, 2001 corresponds to the number 7, 2002 – 8, 2003 – 9, and so on. The lunar year number is incremented in order, and can be from 1 to 19. If the year number is 19, as for example, in 2013, the number next year is back to 1, etc. So, the number 2014 is 1.That is, if you count the number of lunar 2020 will be equal to 7. Denote it by L.

Now, to find out the lunar day, it remains only to substitute all numbers into formula:
N=(L*11)-14+D+M.
For the date March 2, 2020 preliminary result of the calculation will be: N=(7*11)-14+2+3=68.
Why preliminary? Because the lunar month of 29.5 days. Therefore, you must repeatedly subtract 30 from the number until the result becomes less than 30. 68-30=38, subtract 30 again, turns 8. So, on March 2, 2020 will be the eighth lunar day.

# Advice 2: How to determine the lunar day

The modern common calendar is based mainly on the observation of the Sun. It is very different from the lunar cycle. If you want to know what day of the lunar calendar, you need to make some effort to search for information.
Instruction
1
Take the data from the tear-off calendar. Virtually all of them contain information about moon day of the cycle and the phase of a celestial body during this period.
2
Calculate the lunar day, the special computer program. Because the changes from daylight occur at the level of the calculation days, the program will need to specify not only the date but also the time and also the geographical coordinates. This is especially important if you are building a lunar horoscope by time of birth. The system will give you data not only about the moon day, but the closest to the date of the new moon and the full moon, and the rising and setting of the moon in a particular period.
3
Find out day of the moon alone. The lunar cycle begins with the new moon, which you can fix yourself, and lasts for about 29 days. Thus, the fifth day after the new moon and will be the fifth day of the lunar cycle. But this calculation does not take into account that one day in the Gregorian calendar can fall on a two moon day. You can fix this, if you count the new day with the rising of the moon.
4
Get information on moon day according to different calendars. The Islamic year according to the lunar calendar consists of 354 days, so it dates constantly shifted with respect to the solar calendar. It is best in this case to use the comparative tables of calendars. For example, one shows that the first number of the first month of Muharram in 2012 will occur November 15 on the solar calendar. Note that the start date is in the lunar calendars. For example, in 2012 the Chinese year begins on 23 January in the Gregorian calendar.

Received information about moon day use for the horoscope. His accuracy will be higher, if you except the dates indicated and the time and place of the observation of the moon or any event.
Note
Lunar calendar by the hour is not the same as solar. New moon day is not 24:00, and some time for a Sunny day. Therefore, on March 2, 2020 in some time of the day, the eighth day of the moon will change the ninth.
