Create automatic calendar

I am trying to develop a calendar that automatically populates itself with dates and non weekend days each month also being numbered. Attached is the spreadsheet. The big issue is getting the dates to stop at the right time 28, 39, 30 or 31. It works fine now, except for February. I can't seem to get the additional nested IF statements in there to include for Feb on both leap and non-leap years. I know only need the formula in Row 38, as the last week is the only one that is an issue. I have been trying this for a couple days now and keep getting errors. Any help would be appreciated.

Also, if I'm attacking this completely wrong, I'd be open to listening to that too. Is there a simpler way to create this calendar??

Thanks for you help!!
