Calculating date and time in business days other than Saturday/Sunday

**russ101** · 09-27-2012, 05:02 PM

Hi All,

I have been using the below formula for a while to calculate the time it takes to close our help desk tickets, in hardcoded business hours (5AM to 6PM) given the normal business days (Saturday and Sunday). It works like a champ - however, now I have a few people working in the Middle East and their weekend is Thursday and Friday -

How can I tell this formula to count the business days Saturday thru Weednesday? Or any other forumal out there that will do that job?

=IF(COUNT(H10,I10)=2,24*((NETWORKDAYS(H10,I10)-1)*("18:00"-"5:00")+IF(NETWORKDAYS(I10,I10),MEDIAN(MOD(I10,1),"18:00","5:00"),"18:00")-MEDIAN(NETWORKDAYS(H10,H10)*MOD(H10,1),"18:00","5:00")),0)

Hello russ,

Since you are on Excel 2010 use NETWORKDAYS.INTL in the [weekend] field use 6.

Haseeb is correct but if you want a formula compatible with earlier excel versions you can also modify your existing formula by adding "+2" to every date in the NETWORKDAYS functions, like this

=IF(COUNT(H10,I10)=2,24*((NETWORKDAYS(H10+2,I10+2)-1)*("18:00"-"5:00")+IF(NETWORKDAYS(I10+2,I10+2),MEDIAN(MOD(I10,1),"18:00","5:00"),"18:00")-MEDIAN(NETWORKDAYS(H10+2,H10+2)*MOD(H10,1),"18:00","5:00")),0)
