Is 51 hours and 15 minutes the answer to your example above?
I have an old UDF I wrote to figure net hours worked. Wanted to see if it might help you out???
If you would like to include the valid holiday dates for (Australia?), say... for the next year, I can incorporate these holidays into the function.
Not hardcoded, but I would like to use valid holiday dates so you can test it out for yourself.
Thanks,
Tom

Hello Pat
credit for following to Daniel.M (daniel.maher@bigfoot.com)

1. your times in Col A and Col B, threshold times in cells named sT and eT, holiday list named H_D (it is not essential to name the ranges)
2. ensure Analysis ToolPak is installed
3. result in hours
=NETWORKDAYS(A3,B3,H_D)*(eT-sT)-(NETWORKDAYS(A3,A3,H_D)*MAX(0,MIN(eT,MOD(A3,1))-sT))-(NETWORKDAYS(B3,B3,H_D)*MAX(0,eT-MAX(MOD(B3,1),sT)))

4. result converted to rounded decimal (relevant if you multiply result by a rate per hour)
=ROUND((NETWORKDAYS(A1,B1,H_D)*(eT-sT)-(NETWORKDAYS(A1,A1,H_D)*MAX(0,MIN(eT,MOD(A1,1))-sT))-(NETWORKDAYS(B1,B1,H_D)*MAX(0,eT-MAX(MOD(B1,1),sT))))*24,2)

Note. adjust the references to fit your information.

Hi Dave.
I tried the above function with a return of 3:15?

=NETWORKDAYS(A3,B3,H_D)*(eT-sT)-(NETWORKDAYS(A3,A3,H_D)*MAX(0,MIN(eT,MOD(A3,1))-sT))-(NETWORKDAYS(B3,B3,H_D)*MAX(0,eT-MAX(MOD(B3,1),sT)))

Cell A3 = 8/6/2002 9:00:00 AM
Cell B3 = 8/13/2002 3:15:00 PM
Range("sT") = 8:00:00 AM
Range("eT") = 5:00:00 PM
Range("H_D") = 25-Dec-02,26-Dec-02,1-Jan-03,26-Jan-03

The answer should be 51 hrs and 15 minutes.
Do I have the arguments set up correctly?

Thanks,
Tom

PS Nevermind. It works! I had the formatting wrong. Returned 51.25

Update on this formula w/calendar - PLEASE HELP TODAY......

Please refer to the e-mail located at www.mrexcel.com/board2/printview.php?t=20483&start=0. We are looking at implementing this type of format, but we will need to use a variable calendar (meaning that the work day won't ALWAYS be, say 6:00-4:00 p.m. ). Does the user or Mr. Excel know how to implement this into the equation? We'd like to get an answer today, if possible.

Thanks for your awesome help!

Laura

Hello Everyone,

I have a need for calculating the hours in decimal format from a start date cell to an end date cell in the format mm/dd/yyyy hh:mm in much the same way described here in this post. I vaguely remember how to setup the ranges, so all you have to do is reference "sT", "eT" and "H_D". Could someone refresh my memory on this, please.
