To count days within a month in Excel, use the formula `=DAY(EOMONTH(date,0))`. Replace `date` with a cell reference or hardcoded date. For example, to find the days in September 2023, input `=DAY(EOMONTH("2023-09-01",0))`. This calculates the last day of the month, and `DAY` extracts the day value, giving you the total number of days.
