Social Media Holidays Key Marketing Dates 2023 UK

Whether you’re looking for inspiration for your Instagram posts or need to create content on your blog, you’ve come to the right place.

Get inspired for each month of the year 2023 with lots of key dates that you can plan your content around or use to build your community.

I have included key marketing dates and holiday calendar for the UK, as well as some US ones that are still relevant.

You will also find the Instagram hashtags to use for each of these holidays. For some of these, there are multiple hashtags that you can use.

Why do I need a Social Media Calendar?

You might be wondering if you would even need a social media calendar at all.

Quick answer: yes, you do!

A social media content calendar will not only help you create useful and relevant content, but it will also keep you motivated and accountable for each month of the year.

Here are a few reasons why you need to use a social media calendar for your content strategy:

1. Content ideas for when you’re stuck

We all get to that point in our content creation journey where we get a bit stuck. We feel like either we’re being repetitive with our content (which is not always a bad thing if done right).

Or we might just be completely out of ideas.

Psst. I also wrote about 45 Instagram Stories Ideas if you need more inspo. Or maybe you need help knowing what, when and how to post on Instagram.

This is where the marketing holidays calendar will come in handy.

You obviously won’t want to celebrate or bring awareness to ALL of these social media holidays. But you can go through each month and pick the ones that are relevant to you or your niche.

This will make creating content easier.

It might also spark some post ideas you might not have thought of otherwise.

2. Pitch to brands for campaigns

Here’s one thing that is not often talked about. Brands create their influencer campaigns around major (or sometimes small) holidays.

You can better leverage your content creation skills if you show that you really understand your audience. And you have a specific content plan in mind.

So rather than writing emails saying: “Hi, let’s collaborate”.

Which – spoiler! – will most likely not get you a response back.

Instead, write an email along the lines of: “Hi, I am planning an Easter Day activity ideas for kids and I think your product would be a great feature in it. If you have any influencer campaigns around Easter Day, I would love to help out.”

Of course, maybe elaborate that email – I just wrote the gist.

But you get my point.

This type of email will make you look more professional. And it will show you know what you’re on about. Brands appreciate that.

3. Community feel

You can also use the social media calendar to bring awareness to a cause that is close to your heart. It can help build that community feel in your audience.

By using the right hashtags, you can also bring in more followers that are like-minded and have similar values to you.

And that is exactly what you want in your followers – people who are actually interested in what you have to say.

  1. Hi, It says that this is for 2022, but I’ve noticed the other comments are from 2021 and the dates for things are wrong – they are 2021 dates, not 2022?

  2. Thanks for this but seems like some of the dates still reflect 2021 like mother’s day was on the 14th of March last year and it should be the 27th of March this year in 2022?
