Question

These variables are string

Question: How can I Subtract them and returning

Answer 1

var startTime = "0:10";
var endTime = "1:20";

var s = startTime.split(':');
var e = endTime.split(':');

var end = new Date(0, 0, 0, parseInt(e[1], 10), parseInt(e[0], 10), 0);
var start = new Date(0, 0, 0, parseInt(s[1], 10), parseInt(s[0], 10), 0);

var elapsedMs = end-start;
var elapsedMinutes = elapsedMs / 1000 / 60;
