Well, I have the following code in javascript:

< script type = "text/javascript" >
  function teste() {
    var date1 = document.getElementById("data");
    var date2 = document.getElementById("data2");
    var timeDiff = Math.abs(date2.getTime() - date1.getTime());
    var diffDays = Math.ceil(timeDiff / (1000 * 3600 * 24));
    alert(diffDays);
  } < /script>

In html I have the following code:

Book from: <input type="date" name="data" id="data" />

Up to: <input type="date" name="data2" id="data" onblur="teste()" />

I'd like to know why I'm following the date on inputs does not show a alert telling the number of days.

Notice that when you use document.getElementById("data") this alone does not give you the value of input . You need to get the property .value to know the value.

Then, since you want to use getTime() you have to convert this string that document.getElementById("data").value gives you back on a date. In this case you should use

var date2 = new Date(document.getElementById("data2").value);
var timeDiff = Math.abs(date2.getTime() - date1.getTime());
