No, I haven't done this already, but I'll see whether I can help.
>I need some fancy date functions....
>First, I need to know the last day of a givin month...
You can go to the first of the next month, and subtract one. For instance, for month 5, 2003, you can use
date(2003, 5+1, 1) - 1. Additional adjustments are required for month 12.
>Then I also need to be able to determine the 1st, 2nd, 3rd, 4th, last [monday, tuesday, whatever] day of the month.
>In other words, the user would select the 4th Thurday of Oct, 2003 - I need a way to know that is Thurday Oct 23, 2003.
I would just loop through the first days of the month, until you find a Thursday. Then, to get the 4th. Thursday, add
7 * (4-1) days.
HTH,
Hilmar.
