Count eligible dates between two endpoints

Fill C2:C5 with the signed number of eligible dates from column A through column B, including both endpoints when they are working dates. Apply the text weekend mask in G2 and closure dates G4:G7. Reversing the interval reverses the sign; an all-closed weekly mask returns zero.

The answer cells begin blank. Enter a reusable formula and check it against the published practice datasets. Hints and the solution are available when you choose them.

A checkpoint records a fresh check of every dataset. This attempt tracks built-in hints, solutions, steps and worked examples; it does not establish independent authorship.
