Add business days to a date excluding public holidays

You can add a certain number of business days to an existing date by using the WORKDAY.INTL function.
The public holidays that we want to exclude are in cells "A3:A5".

	A
1	=TODAY() = Saturday 01 October 2022
2	=NOW() = Saturday 01 October 2022 04:32:20

6	=WORKDAY.INTL(A1,5,,A3:A5) = Wednesday, 12 October, 2022 12:00 AM
