Dear Calendar People,
Common year – 365 days/year

4 – 91 – 1
5 – 73 – 0
6 – 60 – 5
7 – 52 – 1
8 – 45 – 5
9 – 40 – 5
10 – 36 – 5
11 – 33 – 2
12 – 30 – 5
Leap year – 366 days/year
Days per week – number of weeks/year – remainder
2 – 183 – 0
3 – 122 – 0
4 – 91 – 2
5 – 73 – 1
6 – 61 – 0

8 – 45 – 6
9 – 40 – 6
10 – 36 – 6

We will notice that seven days per week gives a remainder of one during common year and two during leap year. The remainder gives the number of blank days to make the calendar perpetual. To make the Gregorian perpetual, with twelve months per year, blank days have to be used.
