DateDiff Problem with the Year 2000

[Smiller]

I am having a problem calculating the proper age of people if they were born in
the year 2000

<cfset bydate=#dateformat(#todaydate#,"mm/dd/yy")#>
<cfset year="#datediff("yyyy",form.bday,bydate)#">

I enter my daughters bday 2/16/2000 and it returns her age as 4 instead of 5.
Same with anyone else born in the year 2000.

Has anyone else had this problem. Is there a fix? Is it my code?

Thanks

Sharon
