Michael,

4th, 5th, and Last are different, and should not be mixed up.

Indeed.

And in the very next paragraph I proposed a simple way to do that.

You suggested:

| So the other option is to, in that case, reveal a control (radio buttons) to select between "fifth" and "last", probably just below the control that selects between "day of the week" and "day of the month”

Would this work if the event was initially scheduled when the “Last” was also the “Fourth”, rather than the “Fifth"?

It just seems like the existing algorithm was designed for 28 day months, rather than try to correct its possible/probable mistakes, doesn’t it make more sense to just to start with a 31 day month in mind?
