I can get the current date object like this:

var currentDate = new Date(); 

How can I add 20 minutes to it?

var twentyMinutesLater = ?; 

Answer 1

Use .getMinutes() to get the current minutes, then add 20 and use .setMinutes() to update the date object.

var twentyMinutesLater = new Date(); twentyMinutesLater.setMinutes(twentyMinutesLater.getMinutes() + 20);
