In C4: =MAX(MIN($B4,C$2)-MAX($A4,C$1)+1,0)

Fill to the right to N4.

See the attached version.

You had dates in 2121 and 2222; I have corrected that.

Thank you for your quick response, in your solution its returning 93 days between start date and end date, however it should be 92 days...i tried to correct ,,but not finding..:-(..can you help


Simplified example:


Start Date = November 19, 2021

End Date = November 22, 2021

The difference is 22-19 = 3 days, but the time interval contains 4 days: November 19, 20, 21 and 22.
