The Complete List of Social Media Holidays (2021 Edition)

The Complete List of Social Media Holidays (2021 Edition)

Organic reach is pretty hard to find for brands in 2021, with the rare exception of social media holidays. When coupled with the right hashtag, these holidays provide businesses with an occasion to reach a like-minded crowd.

Who makes social media holidays up?

Some days are the byproducts of marketing campaigns. Some were declared by official organizations such as the United Nations. Others seem to have been manifested by the sheer absurdity of the Internet.

Some days have multiple holidays, such as May 7, which happens to be National Beer Day in the United States and World Health Day. Some days are about serious issues, other days are National Just Because Day (August 27). Some are strictly social media holidays, while many are holidays off social media, too.

Not every social media holiday is worth celebrating. Find the holidays that fit your niche.

This approach increases the odds of connecting with people around shared values and interests rather than gimmicks.

Fenty Beauty: Black History Month

Fenty Beauty inaugurated this year’s Black History Month with a little history lesson of its own, courtesy of its founder, Rihanna.

Way back in 2011, a Twitter user offensively asked why Rihanna’s hair looked “so nappy,” in the music video for her song “Man Down.” In response, the music and business mogul clapped back: “Cuz I’m black bitch!!!!” Seven years later, Fenty Beauty launched a liquid eyeliner with the iconic name: “Cuz I’m black.”

The unapologetic, empowering line speaks both to Fenty Beauty’s brand purpose and audience. We give it a Clapback-lipstick-wearing chef’s kiss.

Knix: International Women’s Day

Knix CEO Joanna Griffiths delivered a supportive message on International Women’s Day… in the midst of delivering twin girls. It really doesn’t get more on-brand than that.

Heartfelt and urgent, the post demonstrates the intimate apparel founder’s priorities, which includes rejecting investors who frown upon fundraising while pregnant.

Food for Soul: Carbonara Day

While we’d all like to celebrate Carbonara Day, it suits some organizations, such as Food for Soul, more than others. Founded by Italian chef Massimo Bottura and Lara Gilmore, the non-profit organization used its food-salvaging ingenuity with a banana-peel carbonara recipe. Putting the “care” in #CAREbonara day, followers were encouraged to donate and share with others.

WWF #WorldWithoutNature: World Wildlife Day

Inspired by One Minute Briefs, World Wildlife Fund challenged brands to participate in World Wild Life day by removing nature from their logos. The goal behind the campaign was to create a stark portrait of a world without nature.

As planned, #WorldWithoutNature generated a great deal of social awareness and conversation, including an astute observation from climate activist Greta Thunberg:
