Heyy everyone,


I wonder if you can help, I am not the best at Airtable so rely mostly on learning as I go and your threads.


I currently have several columns which count the time(days) between Date 1 and Date 2 but now I am looking to make it exclude a list of public holidays, currently, it just measures working days.


So this is the formula currently -


IF(OR({DATE 1} = BLANK(),{Date 1}<{Date 2}), BLANK(), MAX(WORKDAY_DIFF({Date 2},{Confirmed Date 1})-1,0))


But I can not seem to figure out how to make this formula not count the below, I’d have to implement this into several columns with similar formulas !


01/01/2021

02/04/2021

05/05/2021

31/05/2021

30/08/2021

Any help is welcomed 🙂


Thanks

Hi @Theo_Djerkallis and welcome to the community!


You can incorporate WORKDAY_DIFF()


in your formula, which gives you the possibility to exclude holidays. Do mind it will also exclude weekends.



Also see the formula field reference.


Ah, my bad, I see you’re already using WORKDAY_DIFF(). Have you tried adding your holidays into the formula like:


WORKDAY_DIFF({Date 2},{Confirmed Date 1}, 2021-01-01, 2021-04-02, …)?


You can create a hidden field where you put in all the holidays, so it is a little bit less static.



with “Calculation” = WORKDAY_DIFF({date 1}, {date 2}, holidays)
