Staying Current: Automating Copyright Year Updates

The rumble and echoes of fireworks die away, and the New Year begins. With 2024 upon us, millions of websites across the web are unintentionally stuck in the past, still showcasing last year's date in their copyright footers.

Consider this your annual reminder: it is time to update the year in your website footers and copyright notices!

And, if you haven't yet found a way to automate this (it's 2024, you really should have done by now!), then now is an opportune time for me to walk you through a few different techniques that will automate this process for you in the future, instead of spending your New Years morning doing find‑and‑replace across multiple different codebases...

Why Does the Wrong Year Matter?

It may seem minor, but updating the copyright year on a website is the sort of detail that holds a little more significance than you might initially think. As much as anything else, it's about professionalism; the perception of currency and being up‑to‑date rather than anything more substantial around legal risk.

Firstly, an up‑to‑date copyright notice contributes to a website's credibility; it shows visitors that the site is actively managed and that its content is more likely to be current. This is especially important in today's digital landscape, where the freshness of the information you publish can influence user trust and engagement.

From a legal perspective, whilst copyright protection does not hinge on the date displayed in the notice (nor suddenly expire if you do happen to go a few hours with the previous year on‑show), having the ‑ correct ‑ current year can be beneficial for some scenarios. It serves as a public indicator of the most recent update, which could then be useful as a way of establishing the timeline of publication or last modification should a copyright dispute ever arise. An accurate and recent copyright date reinforces the assertion that the content is actively protected and managed, and does away with any potential misconceptions an outdated date might otherwise cause.

So, keeping the date in your website footers up to date is a practice that goes beyond mere legal compliance; it shows a commitment to professionalism and diligence in managing a digital presence for you, or for your clients. It's a very small but important detail that enhances the image of a website, offering an indicator that it is a trustworthy and reliable source of information or services.

Automating the Year in Different Languages

So, knowing that you really ought to keep that year up to date, and (still) assuming that you haven't yet found a way of doing it automatically (because in any project, efficiency and automation are key), allow me to share with you some code snippets that I've collected over the years to do just that...

HTML / JavaScript

Although there's no implicit way of displaying the current year in raw HTML (that I am aware of), JavaScript makes this task very straightforward.

Using Vanilla JavaScript

In JavaScript, we can use the getFullYear() method of the Date object to get the relevant four‑digit year number. Combine this with new and you get the full current year. I tend to set this up as a utility function that can be imported and used anywhere across the site, like this:

const getCurrentYear = (): number => new Date().getFullYear();

If you have a static site with no frameworks to lean on, then you can set up a span with the ID 'copyright', and then update it when the page loads like this:

document.addEventListener('DOMContentLoaded', (event: Event) => {  const currentYear: number = new Date().getFullYear();  const copyrightElement: HTMLElement | null =    document.getElementById('copyright');  if (copyrightElement) {    copyrightElement.textContent = `© ${currentYear}`;  }});

This will then output © 2024 for you.

In React

In React, the process is virtually the same. You can either set up getCurrentYear as a utility function (see my code example above), import it into your component, and then output it like this:

import getCurrentYear from 'getCurrentYear';const Component = () => (  <footer>    <span> © {getCurrentYear()}</span>  </footer>);

Or, if you prefer not to use a utility function, then you can wrap it all into your component directly like this:

const Component = () => {  const currentYear: number = new Date().getFullYear();  return (    <footer>      <span> © {currentYear}</span>    </footer>  );};

In Angular

You can bind the current year directly in the template for Angular applications.

Your component (e.g., footer.component.ts) would look something like this:

export class FooterComponent {    currentYear: number = new Date().getFullYear();}

And to use it in your template:

<footer>    © {{currentYear}}</footer>

In Vue.js

You will hopefully have begun to see a reoccurring pattern here when it comes to getting the current year in JavaScript applications. However, just in case, here's a Vue.js example in case you need it:

<template>  <footer>    © {{ currentYear }}  </footer></template><script>  export default {    data() {      return {        currentYear: new Date().getFullYear()      };    }  };</script>

Using jQuery

I hesitate to include this given how significantly jQuery's use has reduced over the past few years, but nevertheless, I know a lot of people who visit this blog are still using it in their legacy applications, and according to Stack Overflow's 2023 Developer Survey, 22.87% of professional developers ‑ and 21.98% of all respondents ‑ are still using it, making it the third most popular (and most‑starred) framework of the previous year:

I'll maintain what I've said before: some things just don't need the complication of a complete framework to implement, but following the same pattern as I've described for vanilla JavaScript above, you could integrate an automatically‑updating date into your jQuery application by populating it into a span with the ID 'copyright':

$(document).ready(() => {  const currentYear: number = new Date().getFullYear();  const copyrightElement: JQuery<HTMLElement> = $('#copyright');  copyrightElement.text(`© ${currentYear}`);});

PHP / WordPress

Getting the current year in PHP is arguably even more straightforward than in JavaScript, simply requiring that we use the date function, passing in the correct DateTimeInterface::format():

<?php echo "© " . date("Y"); ?>

This code dynamically gets the current year and echoes it out wherever you place the snippet. Insert this line of code in the HTML structure of your footer, and it will display the current year.

WordPress

Much like React and Angular are just JavaScript frameworks (and can therefore use vanilla JavaScript), the same is true of WordPress and PHP. In order to ensure that your WordPress site's copyright notice always shows the current year, you just need to find your theme's footer file (usually footer.php directly inside your theme directory), drop the above snippet in place of the static year, and upload the changes.

Ruby on Rails

In a Ruby on Rails application, you can dynamically display the current year by embedding it directly into your views using the Time class:

#  In your view file (e.g., app/views/layouts/application.html.erb)© <%= Time.now.year %>

Python (Django/flask)

Django

In Django templates, you can use the now template tag like this:

<!-- In your Django template -->© {% now "Y" %}

Flask

In Flask, you can pass the current year from your route to the template:

#  In your Flask routefrom flask import render_templatefrom datetime import datetime@app.route('/')def home():    return render_template('index.html', current_year=datetime.now().year)

Then, use it in your Jinja2 template like this:

<!-- In your Flask template -->© {{ current_year }}

.net (C#)

In a .NET environment (particularly in an ASP.NET MVC application), you can use Razor syntax to display the current year in your view (e.g., _Layout.cshtml):

© @DateTime.Now.Year

Java

And finally (for this list at least), if you are working in a Java/JSP application, you can use LocalDate:

<!-- In your JSP file -->© <%= java.time.LocalDate.now().getYear() %>

I should mention here that you could also be tempted to use util.Date().getYear() and then add 1900 to it, but please don't do that; it has been depreciated for many years.

Best Practices and Common Mistakes

Best Practices

• Consistent Implementation

  : whatever the method you choose to use, it's important to make sure that you are consistent across all pages within your application. Inconsistency could lead to confusion and situations where some areas of your site report one date whilst others report another. This is why I like to create a single utility function in my projects and then import and use that everywhere it is needed.

• Use Reliable Time Sources

  : Always use the methods or functions provided by the programming language or framework you are using to get the current year. Avoid hardcoding values ‑ they will simply become outdated.

• Optimise for Performance

  : Make sure that the script or code snippet used does not adversely affect the loading time or performance of your website.

• Plan for Time Zone Differences

  : Websites are global by their very nature, so it is important to consider what impact (if any) time zone differences might play on the displayed year for your application during the New Year transition.

Common Mistakes

• Forgetting to Update them All

  : There's two things to consider here: make sure that every instance of copyright year is changed to your automated approach. You also need to ensure that any other date references on your website are also updated as needed.

• Using Deprecated Methods

  : I'll admit that I'm not a Java developer by any means, so when I first wrote this article, I suggested using a snippet I'd found off the internet, which used util.Date().getYear(). I very quickly came to realise that this had been depreciated literal decades before. So, don't be like me, avoid using deprecated functions or methods (like getYear() in JavaScript or Java); you never know when future versions of the language might remove them altogether.

• Overcomplicating the Solution

  : At the end of the day, it's just a four‑digit number. It needn't be overly complicated, so choose a solution that is as simple as possible for your needs.

Wrapping up

This has probably become one of the longest articles I've written, so I'd best make this snappy: the automatic updating of the copyright year on your website is more than just a trivial detail. Keeping it up‑to‑date and accurate is a mark of professionalism and an indication of a well‑maintained digital presence.

There are lots of ways to achieve this automatically depending on your needs, your framework or language, and your application. None of them are complicated. There's no excuse for hardcoded years, even in the most basic of website footers.
