Quarters between dates?

Is there a way to determine how many quarters have elapsed between two dates? I'm trying to come up with a clever way of doing it, rather than loops and if statements.

An example is I have a start date of December 31st, 1999. An end date of January 2nd 2000. This date range spans 2 quarters. If the start date was Dec 1st, it would only span one quarter.

Any ideas? Received on Tue Jun 14 2005 - 09:47:29 CDT
