Time conversion from 24hrs to 12hrs

Question

I am getting the time like 13.40, but i need to convert it to 1.40.. any one know, what is the best way to do this. i am using jquery to make time.

my code is :

var time = new Date(myDate);
var hours = time.getHours();

alert(hours);

Answer 1

if (hours > 12) {
  hours -= 12;
}

Um, as simple as that.

Answer 2

Use the modulus operator, % for this

var input = "13.40"; 
var atoms = input.split(".");
var output = atoms[0] % 12 + "." + atoms[1];
output; // "1.40";

If you want to prefix with 0 then you can do this

var output = ("0" + atoms[0] % 12).slice(-2) + "." + atoms[1];
output; // "01.40";

If you want AM/PM as a suffix

var output = ("0" + atoms[0] % 12).slice(-2) + "." + atoms[1] + 
     (atoms[0] < 13 ? " AM" : " PM");
output; // "01.40 PM";
