JavaScript Get Date Methods
The new Date() Constructor
In JavaScript, date objects are created with new Date().
new Date() returns a date object with the current date and time.
Date Get Methods
| Method | Description |
|---|---|
| getFullYear() | Get year as a four-digit number (yyyy) |
| getMonth() | Get month as a number (0-11) |
| getDate() | Get day as a number (1-31) |
| getDay() | Get weekday as a number (0-6) |
| getHours() | Get hour (0-23) |
| getMinutes() | Get minute (0-59) |
| getSeconds() | Get second (0-59) |
| getMilliseconds() | Get millisecond (0-999) |
| getTime() | Get time (milliseconds since January 1, 1970) |
Note 1
The get methods above return Local time.
Universal time (UTC) is documented at the bottom of this page.
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
这 getFullYear() method returns the year of a date as a four digit number:
Examples
const d = new Date("2021-03-25");
d.getFullYear();
亲自尝试 »
const d = new Date();
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
这 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.
Examples

d.getMonth();
亲自尝试 »
const d = new Date();
d.getMonth();

Note
You can use an array of names to return the month as a name:
Examples
const months = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"];
const d = new Date("2021-03-25");
let month = months[d.getMonth()];
亲自尝试 »

Note
In JavaScript, the first day of the week (day 0) is Sunday.
Some countries in the world consider the first day of the week to be Monday.

Note
You can use an array of names, and getDay() to return weekday as a name:
Examples
const days = ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"];
const d = new Date("2021-03-25");
let day = days[d.getDay()];
亲自尝试 »

亲自尝试 »
Calculate the number of years since 1970/01/01:
const minute = 1000 * 60;
const hour = minute * 60;
const day = hour * 24;
const year = day * 365;
let years = Math.round(Date.now() / year);
亲自尝试 »
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
| Method | Same As | Description |
|---|---|---|
| getUTCDate() | getDate() | Returns the UTC date |
| getUTCFullYear() | getFullYear() | Returns the UTC year |
| getUTCMonth() | getMonth() | Returns the UTC month |
| getUTCDay() | getDay() | Returns the UTC day |
| getUTCHours() | getHours() | Returns the UTC hour |
| getUTCMinutes() | getMinutes() | Returns the UTC minutes |
| getUTCSeconds() | getSeconds() | Returns the UTC seconds |
| getUTCMilliseconds() | getMilliseconds() | Returns the UTC milliseconds |
UTC methods use UTC time (Coordinated Universal Time).
UTC time is the same as GMT (Greenwich Mean Time).
The difference between Local time and UTC time can be up to 24 hours.
The getTimezoneOffset() Method
这 getTimezoneOffset() method returns the difference (in minutes) between local time an UTC time:
