Note 2
The get methods return information from existing date objects.
In a date object, the time is static. The "clock" is not "running".
The time in a date object is NOT the same as current time.


The getFullYear() Method
The getFullYear() method returns the year of a date as a four digit number:

Examples

const d = new Date("2021-03-25");
d.getFullYear();

Warning !
Old JavaScript code might use the non-standard method getYear().
getYear() is supposed to return a 2-digit year.
getYear() is deprecated. Do not use it!


The getMonth() Method
The getMonth() method returns the month of a date as a number (0-11).

Note
In JavaScript, January is month number 0, February is number 1, ...
Finally, December is month number 11.

d.getMonth();

Try it Yourself »

"June", "July", "August", "September", "October",
"November", "December"];

const d = new Date("2021-03-25");

const hour = minute * 60;
const day = hour * 24;
const year = day * 365;

let years = Math.round(Date.now() / year);
Try it Yourself »

Date.now() is a static method of the Date object.
You cannot use it on a date object like myDate.now().
The syntax is always Date.now().

UTC Date Get Methods
