Using a Calculated Value for a Date/Time Column in SP List

[RLUGO]

Hello SP Community,

I'm trying to create a date/time column in a SP list using a calculated value. I would like to create an "Expiration Date" column (calculated value) by adding 3 months to "Date of Recognition" (date/time column in same list)

This is what I have tried:

=DATE(YEAR([Column4]),MONTH([Column4])+[Column10],DAY([Column4]))

Where: 

- Column 4 = Date of Recognition

- Column 10 = Months Available (default value = 3)

Any help is greatly appreciated!

@RLUGO I can't see anything wrong with your formula; this worked for me:

=DATE(YEAR([Insurance Expiry Date]),MONTH([Insurance Expiry Date])+Months,DAY([Insurance Expiry Date]))

So what result are you getting?

Hi @RobElliott, 

This is the error message I receive when attempting to enter the formula.

 Thank you!

@RLUGO no, it needs to be a calculated column. It won't work in the way you have done it with a date/time column.

@RobElliott I'm looking to do something similar but I would like to create a reminder 1 week before the three months+ date. If i make it a calculated column though it doesn't show up as an option when I try to set the reminder in Automate. Anyway I can do it in a date column?
