Thanks aandi,
It's a nice workaround, better than mine, and simple too ;). But i found a nasty thing when i minus two dates, moreover, when I minus dates that begins 25
years from now, more or less, and today's date. An example:

If I type this:
var a= new Date(); /* today's date, 12/10/99 */
var b= util.scand("mm/dd/yy","12/12/74");

var diff= (a.valueOf()-b.valueOf())/3600/24/365;

Even it's not 12/12/99 yet, it says:

diff=25010.8245180112;

when it should be less than that, and if I minus .5,
it will truncate to 25 years, so the workaround doesn't work here :(.

Hmmm I'm thinking that the problem may be the "+1 day each 4 years" stuff. Can someone confirm this?

Thanks for your time!
