This makes it easy to determine, for example, the 3rd Wednesday of the month. Except I need to be able to determine the last occurrence of a day of the month (let's say the last Friday). As some months have 4 weeks and others have 5, well..that's my problem.

The shown function does nothing more than retrieving the n-th week in a month for a certain numbered day, it does not retrieve the name of said day.

'This' for sure not. Possible however in combination with other, not shown functions.

Calculate the date of the 5th occurence, then check if the result's month is the same as the month in request.
If not, the 4th occurence is valid.

Afair there were two competing solutions, my solution was to use Bascom's convert functions.
You may look that up, it provides the desired solution.
