You're making it too hard.

The date command you have (assuming you have GNU coreutils and dateutils) will do some arithmetic for you

Start here: Time / Date Commands

Keep going! Be sure to read your info or man page for the date command.
Specifically the option:
Code:
   -d, --date=STRING
              display time described by STRING, not 'now'
