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.

8 examples of great social media holiday posts
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.
Time’s Up: International Transgender Day of Visibility
As a charity that advocates for victims of sexual harassment, this post from Time’s Up is a meaningful expression of solidarity with the transgender community. The simple gesture received more than six times the engagement than the post that followed.
National Women’s Law Center: Equal Pay Day
In this TikTok video, the folks behind the National Women’s Law Center break down the significance of Equal Pay Day with cold, hard facts. The explainer drew in more than 47 times more views than the account’s previous post.

Thrive Market: Teacher Appreciation Week
Thrive Market showed its appreciation to teachers with a giveaway. The contest also served as a reminder that the wholesale online grocery store offers free membership to teachers all year round.
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.
?Today nature has disappeared from the logos of the world’s biggest brands ? Here’s why: A #WorldWithoutNature is a world that is incomplete ?? pic.twitter.com/cd8lSfLcAJ
— WWF (@WWF) March 3, 2021
As planned, #WorldWithoutNature generated a great deal of social awareness and conversation, including an astute observation from climate activist Greta Thunberg:
We're today discussing a #WorldWithoutNature as if it meant that “our children won't be able to see pandas in the future” or that “we won't be able to eat certain types of food”.
A world without nature is no world. Stop separating “humans” and “nature”. Humans are part of nature.
