Get the current year in JavaScript

Question

How do I get the current year in JavaScript?

Answer 1

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

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

---

Hijacking the accepted answer to provide some basic example context like a footer that always shows the current year:

<footer>
    &copy; <span id="year"></span>
</footer>

Somewhere else executed after the HTML above has been loaded:

<script>
    document.getElementById("year").innerHTML = new Date().getFullYear();
</script>

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

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

<footer>
    &copy; <span id="year">2018</span> by FooBar
</footer>

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)

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

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:

Answer 5

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 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);
}

li{
  list-style-type: none;
  padding: 5px;
}

button{
  width: 150px;
}

span{
  margin-left: 100px;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

Answer 7

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>

Answer 8

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 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.
