Suppose you have a reference book in front of you.

You want to see if there is anything related to counting the number of
Thursdays within a start date and an end date.

The table of contents lists chapters for:

Counting and Summing Techniques
Working With Dates and Times

Which chapter would *you* look in for counting Thursdays within a start date
and an end date.

Well I suppose I would start with Dates.
As it turned out, my own code file under "Dates" contained
this formula from Myrna Larson...

"Determines the number of occurrences of a particular day, falling between two dates."
A2 = latest date, A1=first date, B1 is number of the day to find (Sunday = 1).
'=INT((A2-A1)/7)+IF(WEEKDAY(A1-B1)+MOD(A2-A1,7)=7,1)

None of the above -- well, below ;-).

The __index__ is where you go to find things in a reference book.
A __good__ reference book would have an index entry for "counting",
with subentries for, perhaps, "days of the week". That is, if there
is
any discussion or examples related to that topic in the text.

I would look in counting and summing, because I already know that
Excel dates are numbers. But somebody who doesn't know that would
probably look under dates and times.

Want to give us a little more of the background of the question?

When you reveal to us the point of this question, will it be entertaining or

It could be both depending on your perspective!

If you had a choice between a reference book or an "online library"

Which would you choose?

I'd look in "counting and summing" first and I'm greedy.

I'd want the hardcopy of the book to thumb through when I'm not in front of a
pc. But I'd rather have a PDF version instead of online. For the most part, I
find web based stuff slow and difficult to traverse.

I wouldn't look in the book at all. I'd look in the excel newsgroups, and
tease out this oldie but goodie from Daniel M.

==================
The number of DOW (1= Sunday, 2 = Monday, ..., 7 = Saturday) between a start
date (A1) and an end date (A2) is :

=INT((A2-WEEKDAY(A2+1-DOW)-A1+8)/7)
