Jot these 2025 UK awareness days into your calendar and add some sauce to your social media marketing.

Knowing what to post on social media is no cakewalk. But with the right UK awareness days up your sleeve, you can create content with that extra touch of meaning and relatability.

To get you started, we’ve listed over 140 (yes, really) key dates to add to your social media calendars.

What is an awareness day?

An awareness day is a date designed to bring attention to critical causes, events and random topics.

Much like the famous Red Nose Day and the much-loved Valentine’s Day, there is pretty much an awareness day for everything.

For example, there is a National Chocolate Cake Day in January. Any excuse, eh?

An awareness day can be based on something small and light-hearted, simply for a bit of fun, or it can be part of a much bigger, deeper conversation.

Why do we have awareness days?

The main reason for awareness days, weeks and months is to encourage people to take action and drive change in some way.

Awareness days are created by individuals, organisations, or charities to mark a particular event, time, or object.

Why awareness days are important for social media marketing

When looking for content ideas, awareness days are an easy place to start.

The beauty of these awareness days is that they become a popular talking point on social media.

The day often comes with its own hashtag that trends because of the popularity and sheer quantity of posts going out on that given day.

Awareness days, weeks, and months count for timely social content that you can plan well in advance. They’re also a fantastic way of taking a trending topic and highlighting your view or efforts as a brand.
