But here’s the kicker: engagement isn’t a free pass. Brands have to earn their spot at the table by tapping into conversations that actually matter, right when they matter. That’s where hashtag holidays come into play—those playful, shareable moments like #DressUpYourPetDay or #CustomerAppreciationDay give you a golden ticket to join conversations already buzzing.

LEARN MORE.

Social media may be saturated, but brand engagement isn’t dipping. Four in five consumers say they’ll interact with brand content as much or more than they do today, according to Sprout Social’s 2026 Social Media Content Strategy Report.

But continued engagement doesn’t mean guaranteed attention. Brands still have to earn it by finding relevant and timely ways to start and participate in conversations.

Hashtag holidays are social media moments that provide a natural entry point into conversations people are already primed to engage with. From #DressUpYourPetDay to #CustomerAppreciationDay, there are hundreds of hashtag holidays to choose from, and by selecting the right ones for your audience, you can reach your goals on social.

We’ve curated a comprehensive list of the top hashtag holidays for 2026. Read on to learn more about how to find the right social-specific holidays to spice up your calendar and brand examples that stood out to us from 2025.

What are hashtag holidays?

Hashtag holidays are social media holidays, like #NationalDonutDay on June 7th, that gain traction on social media through their designated hashtags.

Unlike fast-moving social media trends, they’re predictable moments you can plan for. This gives you ample time to prep. Plus, you get a strong entry point into conversations that matter to your audience through shared cultural moments. After all, according to The 2025 Sprout Social Index, 93% of consumers say it’s important for brands to keep up with online culture.

Every month offers unique opportunities to tap into these social media moments, making your posts feel timely, relevant and engaging.

Creating your hashtag holiday strategy

Here’s how to create a holiday hashtag strategy around the moments that make sense for your brand and audience.

Choose relevant hashtag holidays

Audiences notice when brands show up in cultural moments, and according to Sprout’s 2026 Content Strategy Report, 70% of consumers feel brands are doing a good or excellent job keeping up with trends.

That doesn’t mean brands should jump on every social media holiday. For social teams, the opportunity is in choosing the ones that make sense for your brand and audience, rather than participating in moments just for visibility.

Participation in random trends can erode trust, whereas participation in relevant conversations your audience is already having shows you are listening. Being selective helps build stronger connections.

Listen to your audience and monitor trends

Social media listening shows you if people are already engaging with a holiday hashtag. It provides insights on audience interest and sentiment, versus relying on surface-level insights, like hashtag popularity, that don’t tell you who is using it, how they’re using it or why.

With Sprout Social Listening, your team can monitor discussions related to your industry and brand to identify the topics and hashtags your audience already cares about. And Sprout’s agentic conversational AI, Trellis, can provide data-backed answers to your questions, helping you uncover key insights to make informed decisions about which hashtag holidays deserve your focus.

And when you add in media intelligence, it works in tandem with social listening to help brands ensure they are showing up where their audience already finds value, or will find value.

To understand what news is already resonating on social and beyond, pair Trellis with predictive media intelligence from NewsWhip by Sprout Social. NewsWhip identifies which stories and themes related to those topics are gaining momentum in the broader news cycle, providing early signals into conversations that your audiences may care about next.

Use insights to inform content creation

Once you’ve identified holiday hashtags that align with your audience, the next step is to gather insights to shape content that feels relevant and timely.

Here are three ways you can do that:

1. As the holiday approaches, revisit your social listening data to see which conversations, themes or questions are gaining traction. This shows what people care about right now.
2. Review how other brands in your industry approached similar holidays last year and evaluate what resonated with their audiences. Just because the creative was great doesn’t mean it drove engagement.
3. Look at how your audience engaged with the holiday last year. If it drove little interest in 2025, it may not be worth prioritizing in 2026.

This will give you a clear picture of how people are celebrating this year and help you create content to reflect real-time sentiment and cultural context.

It’s worth noting that insights only create value when they’re acted on. According to the Q4 2025 Sprout Pulse Survey, 55% of global consumers say brands don’t always act on what they hear on social.

Using audience insights to guide your hashtag holiday content helps close that gap and improves the chances your posts will resonate.

Repurpose content and engage your audience

Creating content for hashtag holidays in advance gives you more room to be creative and intentional.

Use an opportunity like this to showcase your brand’s personality. That might mean leaning into humor or referencing cultural moments. It could also involve experimenting with trending formats or adding interactive elements like polls and quizzes that invite your audience to engage.

User-generated content (UGC) is another effective way to boost engagement. Encourage your audience to share photos, stories or ideas related to the hashtag holiday and tag your brand, then feature their contributions in your posts.

If you’re tight on time or resources, repurposing existing content can be just as effective when done thoughtfully. For example, if you’re celebrating #NationalPizzaDay, repurpose an old recipe post with updated visuals, like the example below, or pair it with a trending meme for a fresh spin.

And because hashtag holidays are meant to be fun and collaborative, they’re also a good opportunity to bring in other teams. Loop in your teammates as soon as possible if you’re planning to ask them to participate in a brainstorming session or be on camera.

Know your networks

Social media content creation needs to align with the network. To get the most return for your effort, use social listening insights to determine which network the holiday hashtag is most active on, and where your audience is most likely to engage.

Being selective with both your content and the network will make it feel more native. After all, joining a conversation that’s already happening feels natural. Trying to spark one when the audience hasn’t shown interest in the holiday can feel awkward or forced.

2026 hashtag holidays to include in your calendar (with examples)

Here are some of our favorite hashtags and the brands that nailed their execution in 2025. All dates listed in the tables below reflect the 2026 calendar.

January hashtag holidays

Starting the year strong, January hashtag holidays generally center on fresh starts and learning. Check out the example below for inspiration.

#NationalTriviaDay

As the Jeopardy of hashtag holidays, #NationalTriviaDay on January 4 marks the day every year when people (and brands) can flaunt their niche knowledge.

e.l.f. Cosmetics brought this day to life by asking its audience to test their brand knowledge in a carousel and comment on how many they got right. This approach rewarded fans for their loyalty and taught newer followers about the brand in an engaging way.

Apply it: Gamify your content around the hashtag holiday you’ve selected. Turn product details, brand history, behind-the-scenes facts or trivia questions (like in the example above) into a carousel and get your audience in on the game in the comments.

February hashtag holidays

February’s hashtag holidays focus on connection and care. The brand examples below show how you can use these moments to strengthen relationships and build trust with your audience.

#GalentinesDay

While Galentine’s Day officially originated on the show “Parks and Recreation,” February 13 became widely celebrated on social media as a way for everyone to go all-out for their besties.

Last #GalentinesDay, Silk and Sonder, a monthly wellness journal subscription service, invited followers to tag their Galentine in the comments. Each tag prompted the friend to land on the post and read a series of sweet affirmations celebrating different types of friendships.

Apply it: While many brands use a hashtag holiday to promote products, consider creating content that helps your audience connect with each other. One of the simplest ways to do that is to invite followers to tag their friends.

#NationalPizzaDay

As one of the most delicious hashtag holidays, #NationalPizzaDay on February 9 is an ideal opportunity to showcase your gooey cheese and buttery crust and rally your customers around fan-favorite offerings.

Domino’s launched a National Pizza Day contest to engage its audience. In the comments section of the Facebook post about their giveaway, their most loyal fans were eager to share their go-to pizza order, hoping to win a free large three-topping pizza.

Apply it: People love a chance to win free items. Host a giveaway or contest to celebrate a hashtag holiday.

March hashtag holidays

Many of March’s hashtag holidays are about raising awareness—World Water Day for example—or having fun, like St. Patrick’s Day. There are plenty of opportunities in March to make your audience stop and think, or stop and smile.

#WorldStorytellingDay

#WorldStorytellingDay on March 20 brings an ancient tradition to a modern forum by connecting people through stories. Because this day is so broadly applicable, any organization or industry can participate.

For instance, investment firm KKR participated in this hashtag holiday by sharing an audio clip from its co-head of global private equity talking about what he learned from his father. The post puts the organization’s culture and values on display in a way that fits the network, the audience and #WorldStorytellingDay.

Apply it: Create content that features an authentic story that reflects your brand’s history, values or culture. Feature leaders or employees to humanize your brand and content.

April hashtag holidays

April’s hashtag holidays strongly prompt participation in different ways. #EarthDay asks us to act for the planet and #AprilFools calls for hijinks.

The examples below show how brands can show up while keeping things light and engaging.

#NationalSiblingDay

Let’s hear it for the siblings. #NationalSiblingsDay on April 10 celebrates the special bond siblings share.

Some brands celebrate the hashtag holiday literally. Last year, the Washington Metropolitan Area Transit Authority introduced identical twin police officers in a funny X video where they get quizzed on how similar they really are.

Apply it: If you have siblings working at your organization, consider highlighting them on #NationalSiblingsDay. You can also feature other siblings, like adorable animals or famous families.

#EarthDay

#EarthDay is a hashtag holiday and a movement. Social media helps the cause gain momentum, which is why every April 22 your feeds are flooded with Earth appreciation content.

ADAMA, the global crop protection company, marked #MotherEarthDay with a post highlighting it’s approach of balancing performance with sustainability. The post also highlights specific examples of ADAMA innovations that support both grower productivity and environmental responsibility.

Apply it: Share how your brand is supporting a cause in tangible ways. If you are still working toward progress, don’t be shy. Share your goals and what you’ve accomplished so far.

May hashtag holidays

May’s hashtag holidays celebrate work, cultural curiosity and warmer days. Here’s how some brands are joining these moments in May.

#InternationalMuseumDay

#InternationalMuseumDay, celebrated annually on May 18, shines a spotlight on the importance of museums in cultural exchange and education. It’s the perfect occasion to explore art, history and innovation virtually and in-person.

In 2025, on #InternationalMuseumDay, the International Council of Museums (ICOM) shared a communications kit designed to help museums worldwide participate in the celebrations. Their campaign encouraged museums to engage with the theme by hosting events, sharing stories and promoting their role as knowledge hubs.

Apply it: Make it easy for your community to participate in a hashtag holiday by sharing ready-to-use resources. Toolkits, DIY kits, prompts or templates help turn a hashtag holiday into coordinated action and celebration.

June hashtag holidays

#NationalDonutDay

On the first Friday of June, we celebrate glazed, cream-filled treats on #NationalDonutDay.

In 2025, Dunkin’ gave away free donuts to everyone who purchased a beverage for the social media holiday. The brand created a user-generated content style video for TikTok filmed from the perspective of someone visiting a Dunkin’ location for #NationalDonutDay.

Apply it: It’s hard not to love free stuff. Offering a small giveaway will help generate foot traffic to your store and engagement on social. Even if you aren’t a donut maker, or any kind of food business, you can partner with one to generate foot traffic and make the most of the occasion.

July hashtag holidays

July’s hashtag holidays mix summer indulgence and internet culture with moments focused on generosity, listening and connection. This brand example below shows what thoughtful participation can look like across both lighthearted and more reflective moments.

#NationalPinaColadaDay

If you like piña coladas and posting on social media, #NationalPinaColadaDay will be up your alley. On July 10, restaurants, bars and social media users come together to celebrate a drink that’s basically a vacation in a glass.

Skyline Rooftop Bar posted a slo-mo Instagram video romanticizing the process of making a piña colada to make their audience thirsty, and paired it with some fun facts in the caption.

Apply it: Turn hashtag holidays like this into sensory experiences. Capture the sights and sounds in video, and if you want to take a page from the example, pair it with a quick fact or story.

August Hashtag Holidays

August is full of light and playful hashtag holidays, with plenty dedicated to food and beverages. This month of social media holidays is ideal for leaning into feel-good content. Below, see how one brand interpreted #WorldPhotographyDay.

#WorldPhotographyDay

With over 1.5 trillion photos taken each year globally, it’s safe to say #WorldPhotographyDay has mass appeal. August 19 is an opportunity to share a love of photography.

Nikon USA partnered with the nonprofit Black Women Photographers for a World Photography Day giveaway as part of the #BWPxNikon partnership, which also includes grants and ongoing support for photographers. The activation extended the reach of the social media holiday while reinforcing the goals of the collaboration.

Apply it: Activate long-term partnerships or explore new ones through influencer marketing during hashtag holidays. This expands reach, and in the case of partnerships, reinforces shared goals.

September hashtag holidays

Education, cooperation and travel are all strong themes this month. The following example highlights a practical way to engage with one of September’s many hashtag holidays.

#NationalGrandparentsDay

On the first Sunday after Labor Day in the US (September 13 in 2026), we celebrate all our beloved grandparents on #NationalGrandparentsDay.

To celebrate the occasion, Publix shared a photo of Frank, a cashier in North Carolina, with his grandkids, who work at the same store as him. The post depicted an authentic multigenerational connection that captured the spirit of the day.

Apply it: Use hashtag holidays to highlight real people and relationships within your organization to make your brand feel more human and relatable.

October hashtag holidays

October’s hashtag holidays are driven by awareness and indulgence, blending cause-led moments with food, fun and cultural touchstones. What follows is an example of how to use one of these moments thoughtfully.

#InternationalCoffeeDay

Perhaps the most beloved hashtag holiday of all, #InternationalCoffeeDay on October 1 celebrates our collective love of java.

Surprisingly, the Science family of journals jumped on #InternationalCoffeeDay by linking the moment back to academic life. Instead of posting about coffee itself, they share an article on why scientists should take more coffee breaks, using the holiday to spotlight the realities of research life.

Apply it: Don’t be afraid to repurpose content, like videos, images, blog posts, podcast episodes or UGC, and post it during hashtag holidays. Even if the holiday isn’t an obvious fit, you can make it feel timely by tying it to a relevant insight or story.

November hashtag holidays

November’s hashtag holidays are shaped by impact and participation. The month blends global awareness and advocacy with moments that spotlight commerce, entrepreneurship and consumer behavior.

Below, see how one food brand is showing up for #SinglesDay.

#SinglesDay

Celebrated annually on November 11, #SinglesDay centers on independence and self-celebration. What began as an anti-Valentine’s moment has evolved into a global cultural and commerce event, especially on social.

Australian fashion brand Meshki tapped into a viral pop culture moment—Vogue declaring that “having a boyfriend is embarrassing”—and reframed it through the lens of #SinglesDay. The TikTok features two women reacting to the “announcement” while wearing Meshki pieces, announcing the brand’s Singles’ Day sale in a way that felt timely and native to the network.

Apply it: Look for ways to pair hashtag holidays with timely cultural moments your audience already recognizes. Anchoring holiday content to current conversations helps it feel relevant and engaging, even when there’s a promotional angle.

December hashtag holidays

December is defined by reflection and celebration. These hashtag holidays give brands space to look back, give back and close the year on a more human note. The following examples show practical ways to engage with these end-of-year hashtag holidays.

#GivingTuesday

#GivingTuesday marks the Tuesday after Black Friday when people turn their spending toward nonprofits.

On #GivingTuesday, PayPal posted on LinkedIn about offering fee-free donations and the scale of impact enabled through its network. The post paired a clear call to action with proof points, making participation feel simple and meaningful.

Apply it: Unless you’re an NGO or partnering with one, don’t promote your content on #GivingTuesday. Instead, find a way to amplify or support organizations that are serving communities in need.

#Festivus

Although the show “Seinfeld” ended long ago, it’s still influencing pop culture. In the show, the character George Constanza’s family celebrated #Festivus as an alternative to Christmas. Since then, Dec 23 has become a holiday season hashtag observed by Seinfeld superfans.

Twin Sails Beer released a custom beer before #Festivus, naming it after a quote from the show (“these pretzels are making me thirsty”) to engage their followers with a clever nod to pop culture. Alongside some styled product shots, the Instagram carousel included a clip from the show featuring the quote to bring everyone in on the joke.

Apply it: When it comes to pop culture related hashtag holidays, go deeper than the hashtag by anchoring your content in a specific detail that fans will recognize.

Plan for the always-on holiday season

Audiences are more than happy to engage with brands that show up with the right content in the right moments. Hashtag holidays give you an opportunity to balance planning ahead while staying connected to online culture.

And when you use social media insights to decide which social media holidays to participate in, you can be confident you’re joining the right conversations.
