I want to know if someone has a neet function to add/substract whole years to a date or datetime. It needs to take into account leap years and check that it doesn't produce illegal dates (ex: add 5 years to Feb 29 2004).

I know I could code the long way - but is there some FOXPRO function (foxpro has a function for everything) or ellegant snippet that I can use.

Thanks from frigid Ottawa Canada
