If you want to calculate say add 30 days from today in Command Line, you can make use of the date command (this will work on Linux based OS)
Example:When you use the date command, you get the current date and time in the timezone that you are located in.
# date
Fri Mar 18 12:12:21 PDT 2022
Now in order to add 30 days to the current date, add -d parameter followed by "+30 days" in double quotes,
# date -d "+30 days"
Sun Apr 17 112:12:25 PDT 2022
As you can see the result that we get is the date that is 30 days after the current date.

Add X days to the current date ie Today
