In order to use all other Gregorian year, one needs to find a similar year in range 1970-2037, that behaves like that Gregorian year: Both years have the same length, and they both start in the same day of week.

Step 1 - Divide the Gregorian year by 400, and get a remainder. Example: the remainder of 1969 divided by 400 is 369.

Step 2 - Find a similar year in range 1970-2037 in the table - by the number calculated on step 1. Example: with 369 calculated on step 1 get the similay year 1975, which is in the desired range 1970-2037.
