Hope that helps All you need to do is convert the string produced by the into a Date using the Date constructor new Date("2014-06-12")
code :
 function checkDate() {
   var selectedText = document.getElementById('datepicker').value;
   var selectedDate = new Date(selectedText);
   var now = new Date();
   if (selectedDate < now) {
    alert("Date must be in the future");
   }
 }
<input id="datepicker" onchange="checkDate()" required class="datepicker-input" type="date" data-date-format="yyyy-mm-dd" >

it helps some times I apologize if you were looking for more to the answer...but if the following is right then it should make sense...
(It's late, but i believe the logic is right...)
code :
var now = new Date();
var selectDate = new Date(bdate);
var diff = now.getTime() - selectDate.getTime();
if(diff > 0 || diff == 0) {
  // selected date is in the past or is our current time 
  // (which should be tough to match down to milliseconds)
}
else if (diff < 0) {
  // selected date has not past
}
var now = new Date();
var validFutureDate = new Date(bdate);
var diff = validFutureDate.getTime() - now.getTime(); // in milliseconds
var dayDiff = parseInt(diff/(1000*60*60*24));

will be helpful for those in need Just use: Date.parse(date) > Date.now() for comparison to now, or Date.parse(comparableDate1) > Date.parse(comparableDate2) for general comparison
Here's a JSFiddle

wish helps you I want to use date-time field in HTML as below. However I want to use that value to check that the date is either today's or a future date and not a past date. , Try this:
code :
function myFunction(){
  var inputDate = new Date(document.getElementById("bookingday").value);
  var date = new Date();
  if(inputDate < date){
     alert("Please enter valid date");
  }else{
    alert("Valid date. Thank you");
  }
}
Enter a booking date:<br>
<input type="datetime-local" id="bookingday"><br>
<button onclick="myFunction()">Click me</button>
