How do I get the difference between two Dates in JavaScript?

Question

I\'m creating an application which lets you define events with a time frame. I want to automatically fill in the end date when the user selects or changes the start date.

Answer 1

THIS IS WHAT I DID ON MY SYSTEM.

var startTime=("08:00:00").split(":");
var endTime=("16:00:00").split(":");
var HoursInMinutes=((parseInt(endTime[0])*60)+parseInt(endTime[1]))-((parseInt(startTime[0])*60)+parseInt(startTime[1]));
console.log(HoursInMinutes/60);
