You can create a new date based on your string using Date constructor.

Use Date.prototype.setDate() to set the day of the Date.

Example:

var myDate = new Date('2016-05-10T06:34:17Z');
myDate.setDate(myDate.getDate() + parseInt(10));
console.log(myDate);

Notes: You can create simple "utility" function if you need to use more times this script, example:

var addDays = function(str, days) {
  var myDate = new Date(str);
  myDate.setDate(myDate.getDate() + parseInt(days));
  return myDate;
}

var myDate = addDays('2016-05-10T06:34:17Z', 10);
console.log(myDate);

  • Thanks GibboK. I got it. – Harish98 Jul 29 '16 at 09:35
  • Why the `parseInt()`? `.getDate()` returns an integer, so it should be safe to do `myDate.getDate() + 10`. – Arnauld Jul 29 '16 at 09:40

  • @Arnauld I got your point. I added in case a user pass a string instead of number like addDays('2016-05-10T06:34:17Z', '10'); – GibboK Jul 29 '16 at 09:54

One Liner Solution:

  • Today:

    today = new Date().toISOString()

  • Yesterday:

    yesterday = new Date(new Date().setDate(new Date().getDate() - 1)).toISOString()

  • Tomorrow:

    tomorrow = new Date(new Date().setDate(new Date().getDate() + 1)).toISOString()

Tip: You can add or subtract days to get the exact date from today.
