date

Formula: [Y x D + C] -l

Formula interpretation: Y = 2 after years, D = 0.2422, L = number of leap year, C = 23.042 in the 21st century, the 20th century = 23.822.

For example: 2088 equinox date = [88 x 0.2422 + 23.042] - [88/4] = 44-22 = 22, 9 month 22 is the autumnal equinox.

Exception: the calculation results and 1, 1942.
