=now()+5

Note:
If you created a calculated column with [TODAY] or [Me] functions, you will be get the following error like “Sorry, Something Went Wrong…”

- Once, the calculated column is added, now enter the product name. Then, the delivery date will be automatically created like below.

Scenario 2 – SharePoint calculated column add days to date using another date column
