Attempt to create a future Date instead created a past Date

My current datetime is April 8th, 8:52 PM, and I'm using this code:

//get current time
var now = new Date();

//get current time plus 6 hours in the future
var future = new Date(now.getFullYear(), now.getMonth(), now.getDay(), now.getHours()+6, now.getMinutes(), now.getSeconds(), 0);

//print result
console.log(future.toLocaleString());

The result is 4/6/2016, 2:52:43 AM. The time is actually correct, but the day is somehow going backwards 2 days. What am I doing wrong?

Solution

  • .getDay() returns the day of the week (0-6).

    What you want is .getDate() instead, which returns the day of the month.

    If you are going to do a lot of date manipulation, you should check out Moment.js

    In moment you can just do:

    var future = moment.add(6, 'hours');
