I’m sure there is a better, more efficient way, but maybe this helps:

How to loop for each day between 2 dates ?
thanks you very much.

Try clicking on Aug 6th, pressing the Shift key, and then pressing on Aug 22nd.
It should highlight each of the days between the two dates, set the range, and list the number of days as 17.

If you press the Ctrl key, I believe it selects each day individually instead of as a range/series.

Hold down the Shift key.
