How to Count Cells After a Weekday

To count the number of cells after a weekday (e.g., Thursday), you can use the SUMPRODUCT and WEEKDAY functions.

Example: You are working with a worksheet with the first name in column A, the last name in column B, the date of appointment in column C, and weekdays in column D.

Question: How many appointments are after Thursday?


The result returns 4, so four appointments are after Thursday.

Please note that the formula uses the default return type for the WEEKDAY function, which returns from 1 (Sunday) to 7 (Saturday). As a result, Thursday returns 5, and the weekdays after Thursday are Friday and Saturday. 


  • Step 1: WEEKDAY(C2:C12): The result returns the day of the week for each date;
  • Step 2: (WEEKDAY(C2:C12) > 5): The result returns TRUE if a date is after Thursday; otherwise, it returns FALSE; 
  • Step 3: The double hyphen (or times one) converts TRUE into one and FALSE into zero;
  • Step 4: The SUMPRODUCT function returns the sum of the products of the new array.

Notes: The SUMPRODUCT function

The SUMPRODUCT function adds all the multiplication results for all arrays.


=SUMPRODUCT(array1, [array2], …)


– Array1 is required; the first array is to multiply and add.
– Array2 is optional; the second array is to multiply and add.
