I am not enough of a mathematician to come up with a formula for these, but I did notice some patterns.
Here I show only the right most column of the table above:
Pattern of 8 leap years followed by 7 leap years before the difference between leap years is 6 years |
Repetitions of (8 leap years --> 7 leap years) |
---|---|
8 --> 7 8 --> 7 8 --> 7 8 --> 7 8 --> 7 8 --> 7 |
6 times |
8 (year 757) | |
8 --> 7 8 --> 7 8 --> 7 8 --> 7 8 --> 7 |
5 times |
8 (year 1397, a difference of 640 years) | |
8 --> 7 8 --> 7 8 --> 7 8 --> 7 8 --> 7 |
5 times |
8 (year 2037, a difference of 640 years) | |
8 --> 7 8 --> 7 8 --> 7 8 --> 7 8 --> 7 |
5 times |
8 (year 2677, a difference of 640 years) |
Looks like the cycle repeats itself every 640 years. Here is that pattern for the first 10 000 years:
Years at which the 5 * (8 leap years --> 7 leap years) pattern occur | Difference (years) |
---|---|
1397 | |
2037 | 640 |
2677 | 640 |
3317 | 640 |
3957 | 640 |
4597 | 640 |
5237 | 640 |
5877 | 640 |
6517 | 640 |
7157 | 640 |
7797 | 640 |
8437 | 640 |
9077 | 640 |
9717 | 640 |
10357 | 640 |
