Patterns...

I am not enough of a mathematician to come up with a formula for these, but I did notice some patterns.

Leap year every 7 years.
Except after 8 leap years (56 years), the difference is 6 years.
Then after 7 leap years (49 years), the difference is also 6 years.
There is a repetition of these (8 leap years followed by 7 leap years) as well...

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)

Another pattern?

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
