var DateObj = new Date('October 15, 1996 05:35:32'); 
  
// month from above Date Object is 
// being extracted using getMonth() 
var months = DateObj.getMonth();

</script> 

/div>

var DateObj = new Date('October 33, 1996 05:35:32'); 
  
// month from above Date Object is being  
// extracted using getMonth()
