Time interval overlap with other time interval

[Guest]

Hello

I am trying to evaluate a list of arrival and departure times to see if they fall into the range of a list of time intervals. The list of time intervals, designates a condition of 1, else it is condition 0. I want to evaluate each arrival and departure singly to the list of all time intervals. They arrival/departure and the intervals are on different worksheets. I am not sure if a simple formula will work or do I need to write a macro

Example data on one worksheet....it is 49,000 entries in realit
ARRIVAL DEPARTUR
1/8/01 22:10 1/9/01 1:1
1/8/01 22:15 1/9/01 0:5

Any help would be grea

Hi
not quite sure but if col. A stores the arrivala date/time and col. B
the departure date/time enter the following in C1
=IF(SUMPRODUCT(--('interval_data'!$A$1:$A$10000<=A1),--('interval_data'
!$B$1:$B$10000>=A1))+SUMPRODUCT(--('interval_data'!$A$1:$A$10000<=B1),-
-('interval_data'!$B$1:$B$10000>=B1))>0,1,0)
and copy this down

Below is the gist of a suggestion to you
in your previous post in .misc, ref:

http://tinyurl.com/2tucs

to which you did not provide any feedback ..
[so I'm not sure whether we connected that time?]

Maybe take a look at this previous response ?

http://tinyurl.com/2r7gl
(Subject: Ward occupancy chart)

which is quite relevant and works on
data with structure similar to what you posted

The "Occupancy" derivation in the thread
would be equivalent to your desired "# in system"

If you're interested to have the sample book
(Tracking of Occupancy per hourly band)
just post a "readable" email address here
and I'll send it via private email

Sample is easily adaptable to suit
