In the lunar month, in contrast to the solar month, which formed the basis of the calendar, there are 29.5 days. It begins with a full moon, then the moon grows, in the middle of the lunar month there is a full moon, the moon decreases, and a new lunar month begins. There is a lunar calendar by which you can easily find out which lunar day falls on a particular date. But if the lunar calendar for the desired year is not at hand, then you can make the calculations yourself.

calculator (although calculations can be done in your head), a sheet of paper and a pen
Instructions
Step 1
To calculate the lunar day for a specific number, you need to know:
D - day of the month
M - ordinal number of the month
Y - year For example, take March 2, 2020. For this number
D = 2
M = 3
Y = 2020
Step 2
To find out the lunar day, you need to calculate the so-called lunar number of the year. Each year corresponds to its own lunar number, for example, 2001 corresponds to the number 7, 2002 - 8, 2003 - 9, and so on. The lunar number of the year increases in order and can be from 1 to 19. If the number of the year is 19, as in 2013, then the number of the next year is again equal to 1, and so on. So, the number of 2014 is equal to 1. That is, if you count, the lunar number of 2020 will be equal to 7. Let's denote it as L.
Step 3
Now, to find out the lunar day, it remains only to substitute all the numbers in the formula:
N = (L * 11) -14 + D + M.
For the date March 2, 2020, the preliminary calculation result will be: N = (7 * 11) -14 + 2 + 3 = 68.
Why preliminary? Because there are 29.5 days in the lunar month. Therefore, you need to subtract 30 from the resulting number several times until the result becomes less than 30. 68-30 = 38, again subtract 30, it turns out 8. This means that March 2, 2020 will be the eighth lunar day.
