How this formula works
In cell B3 and C3 are the two dates you want to count the specific weekday between, and in the E3 is the weekday number, please use formula as this:
| =SUMPRODUCT(--(WEEKDAY(ROW(INDIRECT(B3&":"&C3)))=E3)) |
Press Enter key to get the result, then if you need, drag the auto fill handle to apply the formula to other cells.
Explanation
INDIRECT function: returns a valid worksheet reference.
ROW function: returns row number of the reference.
The formula ROW(INDIRECT(B3&":"&C3)), returns an array result as this:
{43933;43934;43935;43936;43937;43938;43939;43940;43941;43942;43943;43944}
Since B3:C3 can be seen as the date range 43933:43944 (the dates are stored as numbers in Excel).
WEEKDAY function: gets the day of week (1-7) from a given date.
The formula WEEKDAY(ROW(INDIRECT(B3&":"&C3)) returns an array result as this:
{1;2;3;4;5;6;7;1;2;3;4;5}
SUMPRODUCT function: returns the result of multiplied and summed arrays.
Now the formula calculates as below:
=SUMPRODUCT(--(WEEKDAY(ROW(INDIRECT(B3&":"&C3)))=E3))
=SUMPRODUCT(--({1;2;3;4;5;6;7;1;2;3;4;5}=E3))
=SUMPRODUCT(--{FALSE;FALSE;FALSE;FALSE;FALSE;TRUE;FALSE;FALSE;FALSE;FALSE;FALSE;FALSE})
