>How can I take {^2003/05/27} and add/subtract whole years and months? For example, I want to add 1 year and get {^2004/05/27} or subtract 2 months and get {^2003/03/27}.

Use GoMonth()

or for finer control, convert it to DateTime and add number of seconds:

For 1 year:

? Dtot({^2003/05/27})+(365*24*60*60)
