How do I add days to a variable created using the Date() API?

Question

The following code gets me the date format as DD.MM.YYYY, which is what I want:

const todayDate = new Date().toLocaleString("ru", {
        day: 'numeric',
        month: '2-digit',
        year: '2-digit'
      })

How do I add days to todayDate (for example, add four days)?

Please refer moment.js . It is a library for Dates and related formatting in JS — Yogesh Kumar Gupta, Jan 28 '17 at 11:10

You can try this, first add the day then do the conversion:

var todayDate = new Date()

var newDate = todayDate.setTime( todayDate.getTime() + 4 * 86400000 );// adding 4 days

var dt=new Date (newDate);
console.log(dt.toLocaleString("ru", {
        day: 'numeric',
        month: '2-digit',
        year: '2-digit'
      }));

Another way similar using setDate.

var todayDate = new Date()

var newDate = todayDate.setDate( todayDate.getDate() + 4);// adding 4 days

var dt=new Date (newDate);
console.log(dt.toLocaleString("ru", {
        day: 'numeric',
        month: '2-digit',
        year: '2-digit'
      }));

You should use moment js if you are going to play around with date , it has a lot to offer.

Why not use `date.setDate()`? – Rajesh Jan 28 '17 at 11:20
@Rajesh setDate will also work , i guess converting to timestamp will be safer. – Suchit kumar Jan 28 '17 at 11:23
@Suchit—adding days by adding multiples of 8.64e7 milliseconds isn't a good idea as not all days are 24 hours long. – RobG Jan 28 '17 at 14:00
