I just ran across this tip and thought I’d archive it here since I’m terribly forgetful.  From your SSH, enter the following:

date -d "1 month 2 weeks 4 days"

…will yield Tue Jun 16 08:21:27 EDT 2009. You can use any of the following variables

• years
• months
• days
• hours
• minutes
• and negatives work too!
