Adding days on calculated column from monday to friday

Question

I need to add a calculated column in SharePoint where I have to add +1 day from Monday to Thursday and +3 on Friday but I don't know how to do it. I did some tests with WEEKDAY without success.

Answer 1

You can use WEEKDAY function like below:

=IF(WEEKDAY(Today())=2,Today()+1,Today())

This will check if today's day is "Monday", If Yes, it will add 1 days to today's date else it will set column value to today's date (Similarly you can add your other conditions to this formula).

Complete formula:

=IF(OR(WEEKDAY(Today())=2,WEEKDAY(Today())=3,WEEKDAY(Today())=4,WEEKDAY(Today())=5),Today()+1,IF(WEEKDAY(Today())=6,Today()+3,Today()))

Reference: WEEKDAY function

Note:

1. This function returns the day of the week corresponding to a date. The day is given as an integer, ranging from 1 (Sunday) to 7 (Saturday), by default.
2. Sometimes comma(,) does not work in formula (I am not sure but it is based on something language or regional settings on your site). So in that case use semicolon(;) instead of comma(,).
3. Return your calculated field as Date and Time.

Answer 2

You could try the below formula:

=IF(OR(WEEKDAY([date])=2,WEEKDAY([date])=3,WEEKDAY([date])=4,WEEKDAY([date])=5),[date]+1,IF(WEEKDAY([date])=6,[date]+3,[date]))
