National Day Calendar®: Celebrating Every Day At National Day Calendar®, we believe every day is worth celebrating. From National Bobblehead Day to National Donut Day, we’ve made it our mission to turn ordinary dates into extraordinary moments. What started as one man’s curiosity about the origins of quirky holidays has grown into a nationwide movement — inspiring millions to pause, smile, and find joy in the little things that make life special. Our story began in 2013 when our founder, Marlo Anderson, noticed how people loved sharing fun “national days” online — but there wasn’t a reliable source to track or verify them. So, he decided to create one. What began as a personal project to document interesting and lesser-known observances quickly captured the world’s imagination. Within a year, media outlets, schools, brands, and everyday fans were checking the calendar daily to see what to celebrate next. Today, National Day Calendar is the go-to resource for discovering and celebrating the days that bring people together. Every single day, we highlight official and registered national days that range from the heartfelt to the hilarious. Take National Bobblehead Day, for example — celebrated every January 7th. It’s a lighthearted day that honors those collectible, wobbly-headed figures that bring nostalgia and smiles to fans everywhere. It’s the kind of day that perfectly captures what we’re all about: simple fun that connects generations and sparks conversations. Beyond fun observances like National Bobblehead Day, we also shine a light on meaningful causes, professional recognition days, and cultural traditions. Each listing has a story behind it — where it started, who inspired it, and why it matters. Our small but dedicated team researches and verifies every observance to ensure accuracy, making National Day Calendar not just entertaining but also a trusted resource. But what really sets us apart is our community. Our followers don’t just read about the day — they live it. Businesses host themed events. Families share photos and traditions. Teachers create classroom activities inspired by each day’s theme. From local coffee shops celebrating National Coffee Day to fans posting their favorite bobblehead collections, people across the country find creative ways to celebrate life through our calendar. We’ve also built the Official National Day Registry, where individuals, organizations, and brands can apply to create new national days. Through this registry, we help stories come to life — whether it’s recognizing an unsung profession, celebrating a cultural tradition, or spotlighting a social cause. Once approved, these new days are added to our official calendar, promoted through our site, and celebrated by millions. Over the years, National Day Calendar has become a trusted partner for media and businesses alike. We’ve been featured on Good Morning America, The Today Show, and in major publications across the country. Brands collaborate with us to launch new observances that align with their values, creating fun, meaningful engagement with their audiences. And while our reach has grown internationally, our roots remain humble — right here in Mandan, North Dakota, where it all began. Our motto, “Celebrate Every Day®,” is more than a slogan — it’s a way of life. We believe that no matter where you are or what you do, there’s always a reason to celebrate. Whether it’s sharing laughs on National Bobblehead Day, honoring heroes on National Nurses Day, or creating your own new tradition, National Day Calendar reminds us that life’s little moments deserve just as much joy and recognition as the big ones. From our small team to our global audience, we’re united by one simple idea: every day holds something worth celebrating. And if we can help people smile, connect, and appreciate the moment — even for just one day — then we’ve done our job. So go ahead: grab your favorite bobblehead, give it a little nod, and join us in celebrating every day!
