Get the current year in JavaScript

Question

How do I get the current year in JavaScript?

Astonishing if there really isn't a duplicate for this. This one is close, but not exact. – Kamasutra

Note that the "current" year is not necessarily the same for everyone on the planet at the same time. One has to consider time zone. Most of the answers here give the current year in the user's local time zone (assuming the code is running in a web browser). – Tillion

Answer 1

Create a new Date() object and call getFullYear():

new Date().getFullYear()  // returns the current year

---

Example usage: a page footer that always shows the current year:

document.getElementById("year").innerHTML = new Date().getFullYear();

footer {
  text-align: center;
  font-family: sans-serif;
}

<footer>
    © <span id="year"></span> by Stack Overflow
</footer>

For other functions in the same family, see: developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/… – Hengelo

To get the year according to universal time use getUTCFullYear() – Bruin

The footer example above would be more clear if it were just: <footer> <span id="year"></span> </footer> – Performing

it is currently december 25th of 2023 and this outputs 2024 – Jalousie

Answer 2

// Return today's date and time
var currentTime = new Date()

// returns the month (from 0 to 11)
var month = currentTime.getMonth() + 1

// returns the day of the month (from 1 to 31)
var day = currentTime.getDate()

// returns the year (four digits)
var year = currentTime.getFullYear()

// write output MM/dd/yyyy
document.write(month + "/" + day + "/" + year)

Use getFullYear() instead of getYear(). See #16297397 – Adama

Answer 3

Here is another method to get date

new Date().getDate()          // Get the day as a number (1-31)
new Date().getDay()           // Get the weekday as a number (0-6)
new Date().getFullYear()      // Get the four digit year (yyyy)
new Date().getHours()         // Get the hour (0-23)
new Date().getMilliseconds()  // Get the milliseconds (0-999)
new Date().getMinutes()       // Get the minutes (0-59)
new Date().getMonth()         // Get the month (0-11)
new Date().getSeconds()       // Get the seconds (0-59)
new Date().getTime()          // Get the time (milliseconds since January 1, 1970)

Answer 4

You can get the current year with one line of JS code.

<p>Copyright <script>document.write(new Date().getFullYear());</script></p>

Answer 5

Such is how I have it embedded and outputted to my HTML web page:

<div class="container">
    <p class="text-center">Copyright &copy; 
        <script>
            var CurrentYear = new Date().getFullYear()
            document.write(CurrentYear)
        </script>
    </p>
</div>

Output to HTML page is as follows:

You shouldn't use document.write() but instead something like innerHTML of a span – Homer

The main thing here is the var CurrentYear = new Date().getFullYear(). The document.write() is secondary, and of course various other solutions exist. You should not mark down my reputation for this. – Capote

1.) Bad practice says you, but others disagree since this is valid vanilla Javascript; 2.) My answer provides new information of how to implement this within an HTML page, and not just console.log(). – Capote

Valid as in working not valid as in good. See the accepted answer for the correct way of doing this – Homer

"Good" is subjective. There is more than one way to skin a cat, and more than one way to solve coding problems. If the solution is simple and works, then why is this not "good" in your humble opinion? – Capote

Well, sir, it is clear that this is not a clear-cut objective standard (and indeed is an open debate), as there are many who disagree with you: #803354 ...and also here: https://mcmap.net/q/46076/-why-not-document-write-duplicate Therefore, your marking my reputation down for your subjective opinion is not very nice since there are others who would disagree with you. Remember the main point here, and that I just provided a simple way to print this to HTML file instead of console.log(). – Capote

Please see the previous two links where you can see HUNDREDS of people who disagree with you. There are also HUNDREDS of people who agree with you, so it is not a clear-cut issue. You insistence upon your way or the high way is quite closed-minded since you cannot be certain if someone may decide that document.write() is the best solution for his/her needs. – Capote

Answer 6

You can simply use javascript like this. Otherwise you can use momentJs Plugin which helps in large application.

new Date().getDate()          // Get the day as a number (1-31)
new Date().getDay()           // Get the weekday as a number (0-6)
new Date().getFullYear()      // Get the four digit year (yyyy)
new Date().getHours()         // Get the hour (0-23)
new Date().getMilliseconds()  // Get the milliseconds (0-999)
new Date().getMinutes()       // Get the minutes (0-59)
new Date().getMonth()         // Get the month (0-11)
new Date().getSeconds()       // Get the seconds (0-59)
new Date().getTime()          // Get the time (milliseconds since January 1, 1970)

function generate(type,element)
{
	var value = "";
	var date = new Date();
	switch (type) {
		case "Date":
			value = date.getDate();		// Get the day as a number (1-31)
			break;
		case "Day":
			value = date.getDay();		// Get the weekday as a number (0-6)
			break;
		case "FullYear":
			value = date.getFullYear();	// Get the four digit year (yyyy)
			break;
		case "Hours":
			value = date.getHours();	// Get the hour (0-23)
			break;
		case "Milliseconds":
			value = date.getMilliseconds();	// Get the milliseconds (0-999)
			break;
		case "Minutes":
			value = date.getMinutes();     // Get the minutes (0-59)
			break;
		case "Month":
			value = date.getMonth();	// Get the month (0-11)
			break;
		case "Seconds":
			value = date.getSeconds();	// Get the seconds (0-59)
			break;
		case "Time":
			value = date.getTime();		// Get the time (milliseconds since January 1, 1970)
			break;
	}

	$(element).siblings('span').text(value);

Answer 7

for current year we can use getFullYear() from Date class however there are many function which you can use as per the requirements, some functions are as,

var now = new Date()
console.log("Current Time is: " + now);

// getFullYear function will give current year 
var currentYear = now.getFullYear()
console.log("Current year is: " + currentYear);

// getYear will give you the years after 1990 i.e currentYear-1990
var year = now.getYear()
console.log("Current year is: " + year);

// getMonth gives the month value but months starts from 0
// add 1 to get actual month value 
var month = now.getMonth() + 1
console.log("Current month is: " + month);

// getDate gives the date value
var day = now.getDate()
console.log("Today's day is: " + day);

Answer 8

Take this example, you can place it wherever you want to show it without referring to script in the footer or somewhere else like other answers

<script>new Date().getFullYear()>document.write(new Date().getFullYear());</script>

Copyright note on the footer as an example

Copyright 2010 - <script>new Date().getFullYear()>document.write(new Date().getFullYear());</script>

This is an unnecessary answer. – Kwasi

is the same as the answer of Jerusalem Programmer slightly different – Kwasi

the question is just get the year in JS, not get the year and place it in the footer. And inn that case, you could have edited the other answer. Anyway... – Kwasi

I looks a lot like what can be found on this website : updateyourfooter.com – Cantina

Answer 9

Instantiate the class Date and call upon its getFullYear method to get the current year in yyyy format. Something like this:

let currentYear = new Date().getFullYear();

The currentYear variable will hold the value you are looking out for.

Answer 10

TL;DR

Most of the answers found here are correct only if you need the current year based on your local machine's time zone and offset (client side) - source which, in most scenarios, cannot be considered reliable (beause it can differ from machine to machine).

Reliable sources are:

• Web server's clock (but make sure that it's updated)
• Time APIs & CDNs

Details

A method called on the Date instance will return a value based on the local time of your machine.

Further details can be found in "MDN web docs": JavaScript Date object.

For your convenience, I've added a relevant note from their docs:

(...) the basic methods to fetch the date and time or its components all work in the local (i.e. host system) time zone and offset.

Another source mentioning this is: JavaScript date and time object

it is important to note that if someone's clock is off by a few hours or they are in a different time zone, then the Date object will create a different times from the one created on your own computer.

Some reliable sources that you can use are:

• Your web server's clock (check if it's accurate first)
• Time APIs & CDNs:
  • https://timezonedb.com/api
  • http://worldtimeapi.org
  • http://worldclockapi.com
  • http://www.geonames.org/export/ws-overview.html
  • Other related APIs: https://www.programmableweb.com/category/time/api

But if you simply don't care about the time accuracy or if your use case requires a time value relative to local machine's time then you can safely use Javascript's Date basic methods like Date.now(), or new Date().getFullYear() (for current year).

Answer 11

Grabbing the class, we can replace it's textContent with year in javascript:

document.querySelector(".yr").textContent = (new Date().getFullYear());

&copy; <span class="yr"></span> Company. All Rights Reserved.

Answer 12

In React, you can use inline js

<p class="font-inter text-sm text-gray-500 lg:mt-0">
    © Copyright {new Date().getFullYear()}. All rights reserved.

Answer 13

If you're using the ES6 Javascript with frameworks like Angular, React, VueJS. Then you should integrate a third-party utility library for your project convenience. DayJS is one of the most popular and lightweight library with Immutable data structures. In dayJS you can get year in one simple line of code like below.

dayjs().year()

There is also a bunch of useful methods as well. So I would suggest you to use the dayjs for your next project.
