Formula to count days, excluding weekends and holidays

Nat O

Hello,

I am looking for a solution to the following problem;

[START DATE] - [COMPLETED DATE] = [DAYS]

I need the days column to calculate the days a project took...which seems simple enough, but I have a [holidays] column that I want to exclude from the count if the dates fall in this range and I need to exclude weekends.

I only want to count the working days.

I tried using the project settings to do this, but it messed up my sheet and is auto-populating the completed date. Not sure if i did it wrong.

Thanks for any help

Sorry i wrote that incorrectly, it should be [Completed Date] - [Start Date]

Hi @Nat O

I hope you're well and safe!

Try something like this.

=NETWORKDAY([START DATE]@row, [COMPLETED DATE]@row, [HOLIDAY DATES]:[HOLIDAY DATES])

Did that work/help?

I hope that helps!

Be safe, and have a fantastic week!

Best,

Thanks Andree, it didnt quite do the trick. I believe the reason being, my holiday dates are not in line with each relevant entry. I am dealing with hundreds of rows and to work out if a holiday falls into each start and completion date would be quite laborious to do manually. The holiday dates are just a sitting in a column, not aligned to anything and i am hoping i can reference them, perhaps with a vlookup to exclude from the count?

This is sounding complicated as I write it out.

Happy to help!

It should work if you have all the dates in a Holiday column.

Can you share some screenshots? (Delete/replace any confidential/sensitive information before sharing) That would make it easier to help.

Thanks for persevering @Andrée Starå

It was easier to quickly replicate how it looks in excel . Does this help?

So the holidays are not "in-line" with the start and end dates they apply to, its just a list of dates i want to exclude.
