Think of how a clock looks at 11:00. No, no, the short hand goes on the 11, not the long hand. Anyway, what time will it be two hours later? 13 o’clock? Uh, NO! It’ll be 1:00. So that means 11 + 2 = 1.

Hah! Ain’t that cool?

And it works on a calendar too. What’s two months after November? Right, it’s January. So once again,
11 + 2 = 1.
