Calculate The Number Of Days In A Month
Category: Formulas | [Item URL]
Excel lacks a function for calculating the number of days in a particular month, so you'll need to construct your own formula.
If cell A1 contains a date, this formula will return the number of days in the month:
=DAY(DATE(YEAR(A1),MONTH(A1)+1,1)-1)
Excel Tips
Excel has a long history, and it continues to evolve and change. Consequently, the tips provided here do not necessarily apply to all versions of Excel.
In particular, the user interface for Excel 2007 (and later), is vastly different from its predecessors. Therefore, the menu commands listed in older tips, will not correspond to the Excel 2007 (and later) user interface.
