Thanks for the answer. Follow up question then regarding the week of the week within the month. I see that you can specify the first and last weeks using the Weekday enumeration. How do you describe the 2nd, 3rd or 4th week of the month?
I stumbled across the answer in the help a few seconds ago:
new Weekday(2, Weekday.Monday) // represents second Monday new Weekday(-1, Weekday.Friday) // represents last Friday
