### Title

Date arithmetic

### Post

I'm new to FMP, using FMP 11 on Mac OS X 10.6.2.

I'm finding it very difficult to do what I think should be a very trivial computation: compute the number of days between any two given dates which can span years. I had thought there would be a function to do this but there doesn't appear to be one.

I did some knowledge base searching but didn't see an article.

Are there external date functions that can be loaded to do this sort of thing efficiently?

Thank you!

Yes, it is trivial: subtract the starting date from the ending date (add 1 if you want the calculation to be inclusive).
