The DateDiffNoWeekends tool in our free SDU Tools for developers and DBAs, has been really popular. Another request that we received though, was how to calculate which date a particular numbers week day is. For example, we might want to know which is the 12th week day of the month. So we've added a tool to do that. It's called WeekDayOfMonth.
It's a function that takes three parameters:
@Year is the year (of the month in question)
@Month is month in question (as a number within a calendar year i.e. March = 3)
@WeekdayNumber is an integer that gives you the position in the month that you are trying to calculate.
One nice advantage of this function is that you can supply a negative @WeekdayNumber parameter, and it will start counting from the end of the same month instead.
You can use our tools as a set or as a great example of how to write functions like these.
