Get tomorrow's date with getDay Javascript

Question

What I am making is a weather forecast website, and what I need is the days of the week (ie. \"Sunday\", \"Monday\", etc.). To get tomorrow\'s date I am just putting \"+ 1\"

Answer 1

To add a day to a javascript Date object you would do :

var date =new Date();
//use the constructor to create by milliseconds
var tomorrow = new Date(date.getTime() + 24 * 60 * 60 * 1000);

Note, getDate.

Date.getDay returns a number from 0-6 based on what day of the week it is.

So you would do:

var date =new Date();
var tomorrow = new Date(date.getTime() + 24 * 60 * 60 * 1000);
var twoDays = new Date(date.getTime() + 2 * 24 * 60 * 60 * 1000);
var threeDays  = new Date(date.getTime() + 3 * 24 * 60 * 60 * 1000);

document.getElementById('tomorrow').innerHTML = weekday[tomorrow.getDay()];
document.getElementById('twodays').innerHTML = weekday[twoDays.getDay()];
document.getElementById('threedays').innerHTML = weekday[threeDays.getDay()];

Edit: Fixing typo

Answer 2

Use (day.getDay() + i) % 7. That will only return results between 0-6.
