where “dates” is the named range B5:B104. To get the first day of the month, we use the EOMONTH function like this: EOMONTH returns the last day of the previous month, to which 1 is added to get the first day of the current month. In a similar way, we use EOMONTH to get the first day of the next month: EOMONTH returns the last day of the current month, to which 1 is added to get the first day of the next month. The literal translation of the logic in COUNTIFS is: greater than or equal to the first day in the current month AND less than the first day of the next month. Alternatively, you could use less than or equal (<=) operator for the last day like this:
Previous and next months
To count dates in the previous month: To count dates in the next month:
SUMPRODUCT alternative
You can also count dates in the previous, current, and next month using SUMPRODUCT function together with the TEXT function like this: Here, dates are fed into the TEXT function to get a month and year string, which is used for comparison in an array operation inside SUMPRODUCT. The result is an array of TRUE FALSE values, where TRUE represents dates in the month of interest. The N function is used to change these values to ones and zeros, and SUMPRODUCT simply sums and returns the array.
