AFAICS, you do not. It converts "dd/mm/yyyy" to a Date Object, but
yyyy/mm/dd is not involved.

Don't let your posting agent line-wrap; posted code should be directly
executable.

or
        var useDate = // via yyyy/mm/dd
          new Date(oDate.value.replace(/(..).(..).(....)/, "$3/$2/$1"))

Should be args.IsValid = useDate <= today

Repeated code should generally be put in a function. When that is done,
and the function is small, temporary local variables do not need long
names.
