A social media holiday calendar can help inspire ideas for social media posts throughout the year. There are dozens of major and obscure social media holidays throughout the year you might be missing. Marketers can join the holiday hashtag party to find new followers and generate creative post ideas.
How to use this social media holiday calendar
Not all of these holidays will be a good fit for your business, and you don't want to create posts that don't move your relationship with customers forward. Keep your focus on building relationships and showing your business in a positive light.
For example, wishing your audience a "Happy National Pizza Day" won't accomplish much. Instead, use the holiday as inspiration to connect creatively with your audience, such as:
Create a poll: Does pineapple belong on pizza?
Invite photos: Show us your pizza today!
Share a relatable picture of your staff enjoying their pizza party to create a feeling of connection.
Sponsor a quick contest with pizza delivery as a surprise. To enter, people might share a post about your business, tell you how they use your product, tag a friend, or like the post.
We give lots more examples of how to use these holidays in your marketing in the calendar below. Use those examples to jog your creativity and tailor our ideas to your industry, audience, and brand image.
