JavaScript get tomorrow's date

Working with dates in JavaScript can get a little tricky. I will show you how you can add 1 day to the current date to get tomorrow’s date. This even works when the month changes.

How to get tomorrow’s date using JavaScript

1. First, we store today’s date in a variable

let today = new Date();

2. Next, we create another variable tomorrow and pass the today variable inside the Date constructor

let tomorrow = new Date(today);

3. And, then we use the setDate method on tomorrow variable to add 1 day to it. We do this by first getting the current date using tomorrow.getDate() and adding 1 to it.

tomorrow.setDate(tomorrow.getDate() + 1) // 1639464689038

This would return us a numeric value like 1639464689038 which is Unix epoch time

Similarily, if you want to set hours or reset it to 00:00:00 then you can call the setHours(0,0,0,0) method as follows

tomorrow.setDate(tomorrow.getDate() + 1)
tomorrow.setHours(0,0,0,0)

So without using any heavy library in your existing codebase you can easily add one date to the current date and get tomorrow’s date using JavaScript.
