JavaScript, get date of the next day [duplicate]

Question

You can use:

var tomorrow = new Date();
tomorrow.setDate(tomorrow.getDate()+1);

For example, since there are 30 days in April, the following code will output May 1:

var day = new Date('Apr 30, 2000');
console.log(day); // Apr 30 2000

var nextDay = new Date(day);
nextDay.setDate(day.getDate() + 1);
console.log(nextDay); // May 01 2000    

See fiddle.

Copy-pasted from here: Incrementing a date in JavaScript

Three options for you:

Using just JavaScript's Date object (no libraries):

var today = new Date();
var tomorrow = new Date(today.getTime() + (24 * 60 * 60 * 1000));

Or if you don't mind changing the date in place (rather than creating a new date):

var dt = new Date();
dt.setTime(dt.getTime() + (24 * 60 * 60 * 1000));

Edit: See also Jigar's answer and David's comment below: var tomorrow = new Date(); tomorrow.setDate(tomorrow.getDate() + 1);

Using MomentJS:

var today = moment();
var tomorrow = moment(today).add(1, 'days');

(Beware that add modifies the instance you call it on, rather than returning a new instance, so today.add(1, 'days') would modify today. That's why we start with a cloning op on var tomorrow = ....)

Using DateJS, but it hasn't been updated in a long time:

var today = new Date(); // Or Date.today()
var tomorrow = today.add(1).day();

Using Date object guarantees that. For eg if you try to create April 31st :

new Date(2014,3,31)        // Thu May 01 2014 00:00:00

Please note that it's zero indexed, so Jan. is 0, Feb. is 1 etc.
