We covered some pretty cool Excel formula’s this week and I hope you’re ready for the last one. I used this one a lot when I still had a day job as a sales- and project manager. This excel formula can be used for determining the end date of a project or a certain time span. Of course you use it in your own advantage by giving it your own twist.
For calculating the end date of a project you’ll need to take the following steps.
· First you’ll to fill in the steps/subprojects with the estimated day’s that are needed for the steps.

· Now first you’ll need to fill in the “special day’s” like national holidays etc. etc.

· Then type in the start date in Cell C2

· Type in Cell D2 the following formula =WORKDAY(C2;B2;$F$2:$F$4)
· And press Enter

· Now you’ll need to go to Cell C3
· And type in =D2+1

· Now it’s time for some magic;)
· Fill in the Cells C3 down to Cell C6 by dragging down the bottom right corner of Cell C3.

· And do the same with Cell D2

And you’re done.
So I hope you all enjoyed this Excel week and if you have any question don’t be shy
and just send me a message. Maybe I can help you. I hope you all have a great weekend and I’ll see you on Monday with some new Tips and Tricks. See you!!

Thank you for the explanation of the WORKDAY function. But, for the example task starting 4/2, going for 8 days with a non-work day on 4/3, I would have thought the end date would be 4/14 with the next task starting on 4/15. What am I missing?
