Hi

With Arrivals in column A, Departures in column B.
In cell C2 enter your required Date e.g. 06/03/2006
In cell D2
=SUMPRODUCT(--($A$2:$A$100<=$C$2),--($B$2:$B$100=$C$2))

Note that this includes the = 06/03/2006 in both parts, as people
leaving or arriving on that day will be present for some part of it.
Adjust the formula as required if you don't want this.

I'm setting up a spreadsheet that includes arrival and departure dates
for
about 500 people. I'm trying to set it up so that I can figure out who
will
be present on a given day. For example All people who will be present
on
March 5. That range would include people arriving January 15 and
departing on
March 6, but also people arriving March 5 and departing on April 10.

Any suggestions on setting up a function and sort command combination
that
would allow me to do this.

Thanks
