CHECKERS

Beautify your commit history!

example

Currently supporting all non-leap years. (modify this yourself to figure out a leap year.)

The Logic

We'll start by adding commits for every other day in a month. Starting from the 1st of the month we will add commits for the 1st, 3rd, 5th, etc.. We'll call this an "odd number month". If we start adding commits on the 2nd, 4th, 6th, etc. we'll call this an "even number month".

If we start with January as an odd number month, the last day of the month (the 31st) will have commits. This means the next month, February, should be an even number month so that Jan 31st will have commits, Feb 1st will not, and Feb 2nd will, and so on.

Following this pattern, January will be an odd number month, february will be an even number month, and since the last day of February is the 28th, and the 28th will have commits, March will also be an even number month. The 1st of march should not have commits, but the 2nd should, and so on.

months with 31 days - 01 03 05 07 08 10 12

months with 30 days - 04 06 09 11

months with 28 days - 02

the formula should be as follows:

month	type	end day
01	odd	31
02	even	28
03	even	31
04	odd	30
05	odd	31
06	even	30
07	even	31
08	odd	31
09	even	30
10	even	31
11	odd	30
12	odd	31

odd numbers, 30 days:

04 11

odd numbers, 31 days:

01 05 08 12

even numbers, 30 or 31 days:

03 06 07 09 10

even numbers, 28 days:

02

The Script

(for non leap years)

replace 2017 with the year of your choice (if choosing a leap year, double check that the odd/even stuff is still correct)
