How to set a JavaScript cookie to expire in 10 years?

Question

The function I'm using sets the cookie expiration in this part of the code:

time += 3600 * 1000;

It expires in an hour. How to set this to expire in 10 years?

Answer 1

Note: toGMTString() is deprecated since Jun 23, 2017, 9:04:01 AM and should no longer be used. It remains implemented only for backward compatibility; please use toUTCString() instead.

For more information: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toGMTString

var CookieDate = new Date;
CookieDate.setFullYear(CookieDate.getFullYear() +10);
document.cookie = 'myCookie=to_be_deleted; expires=' + CookieDate.toGMTString() + ';';

You can still achieve the same result just by replacing toGMTString() with toUTCString() as so:

 var CookieDate = new Date;
    CookieDate.setFullYear(CookieDate.getFullYear() +10);
    document.cookie = 'myCookie=to_be_deleted; expires=' + CookieDate.toUTCString() + ';';
