Oh yeah, I forgot. This return value is in Hours, and fractional part of an hour.
if you try to display it as time: (hh:mm:ss) Excel will assume that you're actually looking at days and the decimal is the fractional part of a day. So, to display it as hh:mm:ss, you'll actually have to convert your number using something like: =INT(E2) &":" &TEXT(INT(MOD(E2,1)*60),"00") &":" &TEXT(INT(MOD(MOD(E2,1)*60,1)*60),"00") Paul ----------------------------------------- “Do all the good you can, By all the means you can, In all the ways you can, In all the places you can, At all the times you can, To all the people you can, As long as ever you can.” - John Wesley ----------------------------------------- ________________________________ From: Paul Schreiner <schreiner_p...@att.net> To: excel-macros@googlegroups.com Sent: Wed, August 29, 2012 11:46:44 AM Subject: Re: $$Excel-Macros$$ Re: NETWORKDAYS Formula to calculate amount of hours How about this logic: You can calculate the number of Networkdays. This INCLUDES the entire day. Your core hours are 6:00am to 7:00pm, or 13 hours, so NETWORKDAYS(A2,B2)*13 gives you the number of h ours in full days of work. Next, determine if the starting and ending days are non-working days. If they are, no adjustments are required. If they're working days, then you have to determine if the start/end time is before 6:00am or after 7:00pm. At the beginning of the date range, if(WEEKDAY(A2,16)<3 will determine if the starting day is a Saturday or Sunday. If it is not, then IF(MOD(A2,1) > 0.25 will determine if the starting time is after 6:00am. at the end, IF(WEEKDAY(B2,2)>5 will determine if the ending date is Saturday or Sunday. If it is NOT, then IF(MOD(B2,1) > 19/24 will determine if the time is after 7:00pm. so, this formula seems to work: =NETWORKDAYS(A2,B2)*13 +IF(WEEKDAY(A2,16)<3,0,IF(MOD(A2,1) > 0.25,0.25-MOD(A2,1),0)) +IF(WEEKDAY(B2,2)>5,0,IF(MOD(B2,1) > 19/24,0,-(19/24-MOD(B2,1)))) Paul ----------------------------------------- “Do all the good you can, By all the means you can, In all the ways you can, In all the places you can, At all the times you can, To all the people you can, As long as ever you can.” - John Wesley ----------------------------------------- ________________________________ From: LJ <ljasonmil...@gmail.com> To: excel-macros@googlegroups.com Sent: Wed, August 29, 2012 8:32:18 AM Subject: $$Excel-Macros$$ Re: NETWORKDAYS Formula to calculate amount of hours Hi Paul, My apologies and thanks for the lesson in etiquette. I was trying to be brief as to not bog people down with unnecessary details. I have a formula that I have been using, as stated, in a previous thread. However, it doesn't work when calculating non-core hours. Simply put, it doesn't matter if I have to use 1 formula to get the total time or a combination of formulas.
