2021 Garden & Outdoor Awareness Days and Key Dates

Updated: Apr 30

If you are struggling for content for your social media activity and looking for inspiration, awareness days can be a great starting place. Every day is dedicated to something. You only have to log into Twitter to see a ‘hashtag holiday’ trending! You might feel they are rather silly but with careful selection, they can be fruitful.

Awareness days were created to draw attention to an issue, to unify people to support a cause or celebrate achievements of society. However, as businesses realised the potential to exploit this as a marketing opportunity, thousands of new awareness days have sprung up.

Unless you are the biggest fan of Nutella and you can find a relevant link to your business, I would stay clear of World Nutella day (5th February if this is you!) So be conscious of not just jumping on the bandwagon with awareness days and ensuring the days you choose are a good fit and the content you share is of value to your audience. They are however a fantastic marketing tool and allow you to show your creative side, have fun and share your passions with your audience. The most popular awareness days on social media will generally involve a hashtag, which means they often start trending. If you can get involved in timely conversations, you’ll be able to reach and engage with a large audience, quickly.

Looking for awareness days and be like disappearing down a rabbit hole, so I have done the hard work for you and created a list of days and important dates to inspire you. You could use these awareness days for your social media content, maybe an Instagram post or a few Tweets to a blog article, perhaps you could run a competition, or you could even use an awareness day as a reason to run your own event. If you discover any I have missed, message me and I'll add them to the list!
