use this regular expression var re =/^([0-2][0-9]|(3)[0-1])(\:)(((0)[0-9])|((1)[0-2]))(\:)\d{4}$/i code "myFunction()" >validate "demo" > function myFunction() { var str = "12:10:1995" ; var re = /^([0-2][0-9]|(3)[0-1])(\:)(((0)[0-9])|((1)[0-2]))(\:)\d{4}$/g; if (str.match(re)){ var result = true ; } else { var result = false ; } document.getElementById( "demo" ).innerHTML = result; }
