Hmmm....

I think I misunderstood, so disregard that last reply.

Take a look at this:

You wouldn't believe how complicated it is to do what you want. This is the
only site I've ever seen that even attempts to address your question.

on a given time range of a day (7:00-23:00) or any other range in a day,
how
would I determine the number of hours that fall in between 6:00-22:00,
00:00-6:00, and 22:00-24:00.

Simply subtract the earlier time from the later time:

A1 = 7:00
B1 = 23:00

=B1-A1

If the later time spans past midnight:

A1 = 22:00
B1 = 2:00

=B1-A1+(B1<A1)

Hi!

One way to count the number of specific weekdays between two dates
(inclusive):

A1 = start date
B1 = end date

=SUMPRODUCT(--(WEEKDAY(ROW(INDIRECT(A1&":"&B1)))=1))

I have no idea what you want in the rest of your post!

In a given date/time range I want to determine how many Sundays there
are
and
on the other full days how many 16 & 8 hourblocks there are. Then I
want
to
total each. Plus on the start and finish days determine how the time
breaks
into each block
