That appeals to my inner geek
Unfortunately, I suffer from CRS and would probably never be able to commit those month/year values to memory
As an aside, the mod function is the
remainder of the formula if you apply long division to it. In your examples:
7 into 25: 3 remainder 4 (3 x 7=21, 25-21=4)
7 into 17: 2 remainder 3 (2 x 7=14, 17-14=3)
If you grew up learning long division, it might be a wee bit easier to do it in your head that way as opposed to trying to do the subtraction steps.
