Hello,

I am trying to set up a formula in a workbook to firstly highlight a range of cells between two given dates. Secondly I am trying to populate these cells based on start and finish dates and the quantity of resource for a given item.

Duration

Column J =((H49-G49)/5)+0.2 (Where 0.2 is 1 Day and a 5 Day Week = 1)

Duration currently = 6.4 but surely this should be 4.4?

Conditional Formatting (Formula Used)

In Cell J49:

=IF(J$7>$H49,"",IF(K$7>$G49,1,""))

This Applies to =$J$49:$DZ$60

The Source Data is set out below:

The cell range J49:O50 contains the outputs based on the working week and the quantity of resources.

I am struggling to apply a formula which can replicate this, can anyone provide me with some guidance?

Thanks

I've had another go at this and used a Network Days Formula to give me the duration. However, when I have an activity that runs across 3 weeks there should be 3 cells highlighted in a colour but so far there is only 2. See Row 12 on the attached sheet.

The conditional format in these cells is =AND($I8<=L$6,$J8>=L$6). I'm also trying to spread the value of 1.6 weeks across 3 weeks i.e. 0.4, 1 and 0.2 and I've tried =IF(AND(T$6>=$I12, U$6<=$J12),1,"") but to no avail.

I could not work with your cell formatting; you will have to correct the range references in the formula. This should make your conditional formatting easier—simply color the cells not equal to "".

Hi,

Thanks for your response. I've changed the divisor to 5 based on a 5 day working week however I seem to be having an issue where both the start and end date both occur in the same week.

Shouldn't =IF(AND(WEEKNUM(C$1,2)>WEEKNUM($A2,2), WEEKNUM(C$1,2)< WEEKNUM($B2,2)), 1, IF(WEEKNUM(C$1,2)=WEEKNUM($A2,2), 1-($A2-C$1)/7,IF(WEEKNUM(C$1,2)=WEEKNUM($B2,2), (1+$B2-C$1)/7, ""))) read something like '=IF((AND(WEEKNUM(D$1,2)=WEEKNUM($A3,2),WEEKNUM(D$1,2)=(WEEKNUM($B3,2),((B3-A3)/5)) ?

So for example in column A2 and B2 where there is a start and finish date of say 08 Jan and 10 Jan 2018 0.6 days should appear however in the current format this is rounded up to "1".

I've corrected for the five-day work week with this.

Thanks for that. I still appear to have an issue with the start and finish date in such instance say where start and finish date of say 08 Jan and 10 Jan 2018 0.6 days should appear however in the current format this is rounded up to "1". Also, is there a nuance to this formula which will account for years? The WEEKNUM format only appears to work within the same calendar year?

Try this.

It will correct for holidays, if you have the list of holidays in a defined name. If you don't want the holidays correction, everywhere you see NETWORKDAYS(< Start >, < End >, Holidays) change the function arguments to NETWORKDAYS(< Start >, < End >).

With holidays, if the end date is a Monday, and that Monday is a holiday, the Gantt will display a zero.
