March is more than just the transition from winter to spring; it is packed with quirky, cultural, and downright fun holidays to celebrate. From honoring swine to embracing mathematical constants, March has an array of weird and wonderful holidays to get creative with.
Whether you want to throw a themed party, engage with customers on social media, or just add some excitement to your calendar, these holidays are worth marking down.
Below are some of the most notable holidays that you might never have thought of celebrating at home, at the office, or even at school.
March 4: March Forth and Do Something Day – Find Something New
A clever play on words, March Forth and Do Something Day is all about taking action – whether it’s exploring something new and exciting or developing a new skill. It’s a day all about motivation and movement. It’s a great excuse for anybody to finally get around to that to-do list.
Businesses, in particular, can encourage employees to participate in professional development activities or host an event where customers share their personal or business goals. Social media engagement can make this a lot more fun for everyone. Ask your followers to share something they’ve been meaning to do and challenge them to do it by the end of the month.
March 6: National Dentist’s Day – Thank Your Dentist
National Dentist’s Day is the day to show appreciation for dental professionals who keep our smiles shining. It’s also a great opportunity to promote oral health awareness.
If you love your dentist, consider leaving them a thank-you note or a positive review online. Businesses in the dental industry can run special promotions, offer free dental check-ups, or share dental hygiene tips with their customers. Parents can use this holiday to teach their kids about brushing and flossing in a fun way, maybe with a reward system for good dental habits.
March 12: Plant a Flower Day – Welcome Spring with Blooms
As winter fades and spring approaches, Plant a Flower Day on March 12 is the perfect moment to usher in the next season of the year. On this holiday, you’re encouraged to plant flowers, whether in your own garden or in community spaces. The object is to celebrate the beauty and benefits of blooming plants.
Gardeners (both hobbyists and professionals) can use this day to start their spring planting, while those with less experience can begin with easy-to-grow flowers like marigolds or sunflowers. Schools and businesses can put on flower-planting events to create green spaces that promote sustainability.
Social media users can participate by sharing photos of their floral creations or offering gardening tips. If you’re short on space, consider gifting a potted flower to a friend or coworker to brighten their day.
March 14: Pi Day – Math (and Pie) Lovers Unite
March 14 is Pi Day, honoring the mathematical constant π (3.14). This geeky holiday, founded in 1988 by physicist Larry Shaw, is widely celebrated with – you guessed it – pie!
Schools and educational institutions often host math-related activities, but businesses can join in too. Restaurants and bakeries can offer pie discounts, while offices can host pie-baking competitions.
March 20: International Day of Happiness – Spread Joy and Positivity
Designated by the United Nations, the International Day of Happiness promotes the idea that happiness is a fundamental human right.
A great way to celebrate is by performing random acts of kindness, whether it’s buying coffee for a stranger, writing uplifting messages to colleagues, or organizing a community event. Businesses can use this day to boost employee morale by implementing fun activities, recognizing employee achievements, or encouraging self-care.
March 21: International Day of Forests – Raise Awareness for Trees
The United Nations established the International Day of Forests to highlight the importance of forests in sustaining life. Each year, this day has a theme related to conservation and reforestation.
Get involved by planting trees, supporting environmental organizations, or simply educating others about the role of forests in climate regulation. Companies can engage customers by donating a portion of profits to tree-planting initiatives or encouraging employees to participate in local clean-up projects.
March 23: National Puppy Day – Love Is In The Air
Who doesn’t love puppies? National Puppy Day, founded by Colleen Paige in 2006, promotes adoption and highlights the joys of having a furry friend.
A great way to celebrate is by visiting a local animal shelter, donating pet supplies, or simply spending extra time with your pup. Businesses can host pet-friendly workdays, run puppy-themed promotions, or encourage employees to share pictures of their pets online. Shelters and rescue organizations often use this day to promote adoption – so if you’ve been thinking of getting a pet, this might be the perfect time.
March 26: Make Up Your Own Holiday Day – Be Creative
If none of the official holidays tickle your fancy, don’t worry – March 26 is all about making up your own holiday! Whether it’s “Wear Your Pajamas to Work Day” or “Ice Cream for Breakfast Day,” this is the ultimate chance to create a holiday that suits your interests.
Businesses can also partake by creating company-specific holidays such as “Customer Appreciation Day” or “Team Spirit Day.” Engagement on social media is a key move here. Urge your followers to share their own made-up holidays and offer prizes for the most creative ones.
March 30: Take a Walk in the Park Day – Get Outside
As its name suggests, this is a great opportunity to get outdoors and take a walk through the park. And, if you consider yourself a floral enthusiast, you could take this time to enjoy the seasonal greenery and flowers that are beginning to bloom.
As the famous saying by Walter Hagen in “The Walter Hagan Story” goes, “You’re only here for a short visit. Don’t hurry. Don’t worry. And be sure to smell the flowers along the way.” Sometimes, we need reminders like these to motivate us to take our time in life and enjoy the scenery it has to offer. There are many benefits to taking walks, whether for your mental or physical health. Plus, spending time outdoors is a great way to take a screen break and get some fresh air.
March 31: World Backup Day – Protect Your Digital Life
It’s probably no surprise that we now have a dedicated holiday to save our digital data. That’s right. World Backup Day is an important reminder to back up essential files and protect data from loss.
You can participate by making sure your computer, phone, and important documents are backed up securely. Businesses can use this day to review data protection protocols, educate employees about cybersecurity best practices, and encourage customers to take digital security seriously.
It might feel like a mundane idea on the surface, but it’s a great reminder of a very practical action everyone should take (at least once a year, if not more often).
How to Keep Track of These Unusual Holidays
With so many fun and unusual holidays in March, it can be overwhelming to keep track of them.
