Datedif

That's pretty annoying, and it seems like it would create inaccurate results.

I wonder if there's a more accurate way to calculate elapsed times. I need the end date to be included in the elapse time.

For example, someone's first date of work is 01/01, and their last day is 09/30. They completed their shift on 09/30 and so they should get credit for have worked that day.
