By far the easiest way: make both dates milliseconds and compare them.
Milliseconds are the only simple way of comparing dates.

var date1 = new Date(whatever);
var date2 = new Date(whatever);

var date1Comp = date1.getTime(); // milliseconds
var date2Comp = date2.getTime();

if (date1Comp < date2Comp)
{
  // date 1 is earlier than date 2
}
