[ExcelVBA] Detecting INVALID dates?

 

*Obviously, a date such as Feb. 31, 1705 cannot be correct. Can I have
Excel "detect" invalid dates? Unfortunately, yes, most are before 1900. I
just read XDATE information hoping to see a way to utilize XDATE into
checking for a valid date, but didn't see one.

Invalid dates play havoc on date calculations, so if I can detect it before
calculation, I can force the user to enter a correct date.

*Thank you.
