Question

determine the difference in time excluding weekends

Asked by: rcmb

I have two dates with time and I need to know the difference in hours between the two times but I need to exclude weekends

For example:
1/5/2009 08:00:00 AM Time 1 (Monday)
1/7/2009 10:00:00 AM Time 2 (Wednesday)
Result = 50 hours

1/8/2009 08:00:00 AM Time 1 (Thursday)
1/12/2009 10:00:00 AM Time 2 (Monday of next week)
Results = 50 hours (does not include 48 hours of weekend)

Thanks for your help,
Curtis

I get the time in hours now by doing the following:
formatNumber(((DateDiff("s",Rs("rcvdDate"),Rs("arriveDate")) / 60) / 60),2)
 
which returns something like 13.6 hours
