How to put special company dates in the date table

[MacieskiJ]

I want to know if there have a way to put certain periods of time that my company will not be working at the date table , for an example , at october there will be an period of 18 days that the company will stop to have some repairs at the systems and i wanna know if i can put that in the date table so i can show more specifically the periods where the days of work will not be counted and the production as well

Hi,
I think the easiest way to do this is by creating a new column in the date table and setting something like:
=if(date >= "START DATE" && date <= "END DATE","OUT OF WORK",date)
You could then filter by this.

I hope that is somewhat clear.
