Willy,
This is probably more than you ever wanted to know. I run special jobs on
certain days of the month.
I picked the first Friday, because the day will always be 7 or less. The 3rd
Thursday was a little more
complicated.
This solution is not elegant, and some of the test for not trying this on a
Monday are still in the code.
I hope I commented them all out. If you do get an elegant solution, I would
appreciate seeing that
solution. There is always someone with a better idea. That's what makes this
business interesting.
