Creating a copyright date that updates automatically

A handy snippet that will give you an easy win with no dependencies.

Practically every website has a footer with a copyright message at the bottom and a date for the copyright. On many of the websites that I've redesigned, there wasn't a simple function that updated the date for the copyright's year automatically. That means someone familiar with coding in HTML was having to manually edit the code each year and change the date themselves.

This is extremely tedious and easy to forget - here's a better way.

Option 1 - insert JavaScript snippet directly in the HTML

This is the simplest method and requires no other frameworks or coding knowledge.

Note: the &copy that we include in the text will display the copyright symbol: &copy.

1. Insert the text

<span>Copyright <span id="copyright-date"></span> &copy</span>

2. Insert the JavaScript snippet at the bottom of the `</body>` HTML tag

<script>
  var date = new Date();
  var htmlElement = document.getElementById('copyright-date');

  htmlElement.innerHTML = date.getFullYear();
</script>

What's happening here is the following:

we're creating a variable to store the date and a variable to store the HTML element that will contain the date
then, we're assigning the date variable to display inside of the HTML element so it will be shown on the page and formatting it to only show the year

Here's a full example for some context on how it will look in your HTML code

<body>
  <!-- HTML code for your page or layout template -->

  <footer>
    <span>Copyright <span id="copyright-date"></span> &copy</span>
  </footer>

  <script>
    var date = new Date();
    var htmlElement = document.getElementById('copyright-date');

    htmlElement.innerHTML = date.getFullYear();
  </script>
</body>

Option 2 - insert it with JSX

If you're already using a library that uses JSX, such as React.js, then you can go about this in a simpler way that's much more readable.

let date = new Date();
let thisYear = date.getFullYear();

let displayCopyright = () => (
  <span>
    Copyright {thisYear} &copy
  </span>
)

// Usage:

<footer>
  //... other footer code
  {displayCopyright}
</footer>

Conclusion

This is a handy way to not worry about manually updating your copyright's date in the footer of your website. Trust me, you'll thank yourself later for taking the extra 1 - 2 minutes that it takes to do this. Happy coding! SL
