How to add 30 minutes to a JavaScript Date object?

Question

I\'d like to get a Date object which is 30 minutes later than another Date object. How do I do it with JavaScript?

Answer 1

var d1 = new Date (),
    d2 = new Date ( d1 );
d2.setMinutes ( d1.getMinutes() + 30 );
alert ( d2 );

Answer 2

You should get the value of the current date to get the date with (ms) and add (30 * 60 *1000) to it. Now you have (current date + 30 min) with ms

console.log('with ms', Date.now() + (30 * 60 * 1000))
console.log('new Date', new Date(Date.now() + (30 * 60 * 1000)))
