What is wrong with your code? What result do you get? What did you expect? Note that not all days are 24 hours long were daylight saving is observed. Possibly a duplicate of [*Add +1 to current date*](http://stackoverflow.com/questions/9989382/add-1-to-current-date). — RobG, Mar 24 '17 at 23:14

Js date object is simple and also smart, doesn't just add 24 hours, accounts for daylight savings and new month/year. Just use the following:

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

var app = angular.module("app", []); 
app.controller("ctrl", function($scope) {

    var todaysDate = new Date();    
    var tomorrowsDate = new Date().setDate(todaysDate.getDate()+1);    
    var formattedDate = new Date(tomorrowsDate);

    console.log(formattedDate);
});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app" ng-controller="ctrl">
    
</div>

You can also use the millisecond value to roll back a whole day from a certain day:

currentDate = new Date();
previousDay = new Date(currentDate - 86400000);
alert(previousDay);

But not all days are 8.64e ms where daylight saving is observed. – RobG Mar 24 '17 at 23:13
