How to calculate the day of December 1st next year and how to calculate the formula


Kimlarson's formula (conversion of day of week and date)
  W= (d+2*m+3*(m+1)/5+y+y/4-y/100+y/400) mod 7
In the formula, D is the number of days in the date, M is the number of months, and Y is the number of years
The normal way is to add 365 or 366 days and then MOD7
