How to Calculate the Minor Snow
Formula: [Y*D+C]-L
Note: Y refers to the last two digits of a year, such as 10 in 2010, 08 in 2008, D=0.2422, L=the number of leap years, 21st century C=22.36, 20th century C= 23.08.
Example: The date of Minor Snow in 2088= [88 × 0.2422 +22.36] - [88 / 4] = 43-22 = 21, so Minor Snow starts on Nov 21.
Exceptions: For 1978, add one to the calculated result.
