You'll need a helper column. In this example I'll make it a checkbox, but you can use whatever works best for you. In the checkbox column use an IF statement to compare the two dates and check the box if they are the same.
=IF([First Date Column]@row = [Second Date Column]@row, 1)
You can then use a COUNTIFS on the helper column to count your checkboxes.
=COUNTIFS([Helper Column]:[Helper Column], 1)

This was fun.
=COUNT(COLLECT(COLLECT(Start:End, Start:End, ISDATE(@cell)), COLLECT(Start:End, Start:End, ISDATE(@cell)), AND(INDEX(COLLECT(Start:End, Start:End, ISDATE(@cell)), MATCH(@cell, COLLECT(Start:End, Start:End, ISDATE(@cell)), true)) > INDEX(COLLECT(Start:End, Start:End, ISDATE(@cell)), MATCH(@cell, COLLECT(Start:End, Start:End, ISDATE(@cell)), true) + 1), MATCH(@cell, COLLECT(Start:End, Start:End, ISDATE(@cell)), true) / 2 = ROUND(MATCH(@cell, COLLECT(Start:End, Start:End, ISDATE(@cell)), true) / 2))))
Not often you get the chance to do a nested collect.
I recommend pauls solution however as mine can't handle duplicates in the dates
Also the start column has to be directly to the left of the end column or it will break

=COUNT(COLLECT(COLLECT([Due Date]:Delivered, [Due Date]:Delivered, ISDATE(@cell)), COLLECT([Due Date]:Delivered, [Due Date]:Delivered, ISDATE(@cell)), AND(INDEX(COLLECT([Due Date]:Delivered, [Due Date]:Delivered, ISDATE(@cell)), MATCH(@cell, COLLECT([Due Date]:Delivered, [Due Date]:Delivered, ISDATE(@cell)), true)) > INDEX(COLLECT([Due Date]:Delivered, [Due Date]:Delivered, ISDATE(@cell)), MATCH(@cell, COLLECT([Due Date]:Delivered, [Due Date]:Delivered, ISDATE(@cell)), true) + 1), MATCH(@cell, COLLECT([Due Date]:Delivered, [Due Date]:Delivered, ISDATE(@cell)), true) / 2 = ROUND(MATCH(@cell, COLLECT([Due Date]:Delivered, [Due Date]:Delivered, ISDATE(@cell)), true) / 2))))
Heres a copy that uses your column names

I recommend adding the helper column as well. But you should modify Paul's formula for the helper column slightly to account for dates earlier than due dates.

Good suggestion, Mike. Thanks. I read "on time" as "same as" and went from there.

I would also consider adding a check for blanks, because in this formula blanks will show up as as "on time".
=IF(NOT(ISBLANK(Delivered@row)), IF(Delivered@row <= [Due Date]@row, 1))

Another good suggestion. That's what I get for not plugging it in to an actual sheet for testing. Haha.
