What formulas do you regularly use which benefit from being 1-based? Note, I'm not asking for instances where the index doesn't really matter and the author of a paper simply chose base-1.

There are clearly cases where zero based is more natural. But I don't regularly use any cases where one based is an improvement.

I will admit that zero-based adds a lot of confusion when communicating to other people.
