JavaScript Get Date Methods

These methods can be used for getting information from a date object:

Method Description
getFullYear() Get the year as a four digit number (yyyy)
getMonth() Get the month as a number (0-11)
getDate() Get the day as a number (1-31)
getHours() Get the hour (0-23)
getMinutes() Get the minute (0-59)
getSeconds() Get the second (0-59)
getMilliseconds() Get the millisecond (0-999)
getTime() Get the time (milliseconds since January 1, 1970)
getDay() Get the weekday as a number (0-6)
Date.now() Get the time. ECMAScript 5.

The getTime() Method

The getTime() method returns the number of milliseconds since January 1, 1970:

Example

const d = new Date();
d.getTime();

The getFullYear() Method

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

Example

const d = new Date();
d.getFullYear();

The getMonth() Method

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

Example

const d = new Date();
d.getMonth();

In JavaScript, the first month (January) is month number 0, so December returns month number 11.

You can use an array of names, and getMonth() to return the month as a name:

Example

const months = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"];

const d = new Date();
let month = months[d.getMonth()];

The getDate() Method

The getDate() method returns the day of a date as a number (1-31):

Example

const d = new Date();
d.getDate();

The getHours() Method

The getHours() method returns the hours of a date as a number (0-23):

Example

const d = new Date();
d.getHours();

The getMinutes() Method

The getMinutes() method returns the minutes of a date as a number (0-59):

Example

const d = new Date();
d.getMinutes();

The getSeconds() Method

The getSeconds() method returns the seconds of a date as a number (0-59):

Example

const d = new Date();
d.getSeconds();

The getMilliseconds() Method

The getMilliseconds() method returns the milliseconds of a date as a number (0-999):

Example

const d = new Date();
d.getMilliseconds();

The getDay() Method

The getDay() method returns the weekday of a date as a number (0-6):

Example

const d = new Date();
d.getDay();

In JavaScript, the first day of the week (0) means “Sunday”, even if some countries in the world consider the first day of the week to be “Monday”

You can use an array of names, and getDay() to return the weekday as a name:

Example

const days = ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"];

const d = new Date();
let day = days[d.getDay()];
