Hello,

I need to calculate the hours and minutes we respond to something but only counting the hours and minutes that fall within 08:00 to 17:00 Monday through Friday.

Example - if we received a call at 09:00 06/01/11 but did not arrive until 10:00 6/2/11 hour 'covered' hours are only from 08:00 to 17:00 so our response would be 11 hours.

Is there a way to put this into a formula? Also, there is no coverage on Saturday or Sunday so they would need to excluded completely.

the information is in 2 different cells

<TABLE style="WIDTH: 193pt; BORDER-COLLAPSE: collapse" border=0 cellSpacing=0 cellPadding=0 width=257 x:str><COLGROUP><COL style="WIDTH: 97pt; mso-width-source: userset; mso-width-alt: 4717" width=129><COL style="WIDTH: 96pt; mso-width-source: userset; mso-width-alt: 4681" width=128><TBODY><TR style="HEIGHT: 39pt; mso-height-source: userset" height=52><TD style="BORDER-BOTTOM: #f0f0f0; BORDER-LEFT: windowtext 0.5pt solid; BACKGROUND-COLOR: transparent; WIDTH: 97pt; HEIGHT: 39pt; BORDER-TOP: windowtext 0.5pt solid; BORDER-RIGHT: windowtext 0.5pt solid" class=xl26 height=52 width=129>Created</TD><TD style="BORDER-BOTTOM: #f0f0f0; BORDER-LEFT: windowtext; BACKGROUND-COLOR: transparent; WIDTH: 96pt; BORDER-TOP: windowtext 0.5pt solid; BORDER-RIGHT: windowtext 0.5pt solid" class=xl26 width=128>Onsite Arrival</TD></TR><TR style="HEIGHT: 25.5pt; mso-height-source: userset" height=34><TD style="BORDER-BOTTOM: #f0f0f0; BORDER-LEFT: #f0f0f0; BACKGROUND-COLOR: transparent; HEIGHT: 25.5pt; BORDER-TOP: #f0f0f0; BORDER-RIGHT: #f0f0f0" class=xl27 height=34 x:num="40632.707638888889">30-Mar-11 16:59</TD><TD style="BORDER-BOTTOM: #f0f0f0; BORDER-LEFT: #f0f0f0; BACKGROUND-COLOR: transparent; BORDER-TOP: #f0f0f0; BORDER-RIGHT: #f0f0f0" class=xl27 x:num="40633.423611111109">31-Mar-11 10:10</TD></TR></TBODY></TABLE>

I'm sure one of our formula wizards will eventually show up and put me to shame. But this appears to work in testing.

Greg,

I think you forgot to add the formula view!!!!! :biggrin:

I'm interested to see how this is solved as well, I couldn't get it to work without creating 100000+ if statements!

Sorry, as I was editing to put in the formula, my ISP decided to have one of its frequent little hissy fits and I couldn't post for about five minutes. :rolleyes:

Meant to add - by using the Networkdays function, one should be able to define a range of holidays to exclude, but I didn't take the testing that far.

<SUP>edit</SUP> I just tried it with a holiday and it appears to handle it well, though I'd test it a bit more were I going to try and using the holidays functionality in NETWORKDAYS(). <SUB>/edit</SUB>

Need a little more info to go on than "can't make it work"...

Did you edit all of the cell references to point to the appropriate cells on your worksheet?

Greg,

I copied my date information into columns A and B on a new sheet and then pasted your formula into column C.

What version of Excel are you using? Around here we pretty much assume Excel 2010 or 2007 unless otherwise specified.

Greg,

I did not think of that. My company uses 2003. Would that make a difference?

thanks

Terri
