National and International Days on May 30

European Neighbors’ Day* (Last Friday in May): First celebrated in 1999 by Atanase Périfan in Paris, this day was created to help neighbors connect in cities where people often feel isolated. What started as a local gathering quickly grew into an international movement. By 2004, other European countries joined in, and now millions participate each year. From small coffee chats to block parties, the day promotes community spirit and simple acts of kindness among neighbors.

Fakesgiving: Started in 2009 by Zach Patton and Clay Dunn in Washington, D.C., Fakesgiving was created for those who couldn’t celebrate Thanksgiving on its traditional date. It began as a way to test recipes ahead of the holiday but evolved into a flexible tradition that gained momentum during the 2020 pandemic. Highlighted in pop culture, including the film To All the Boys: P.S. I Still Love You, Fakesgiving offers a relaxed opportunity to gather with loved ones outside the constraints of November.

International Potato Day: Officially declared by the United Nations on December 16, 2023, this day was created to raise awareness of the potato’s nutritional, cultural, and economic contributions. As a staple crop that helps feed the world and supports rural livelihoods, the potato is also tied to sustainable farming goals. May 30 is now a global occasion to appreciate this vital food source and its role in fighting hunger and poverty.

Loomis Day: This day honors Mahlon Loomis, a 19th-century dentist and inventor who received a U.S. patent for wireless telegraphy in 1872—well before Marconi. Loomis demonstrated early wireless experiments using kites and sought support from Congress to continue his work. Although he couldn’t fully explain the science behind his invention, his vision laid groundwork for modern communication. Loomis Day was founded by Richard Birch of Puns Corp to recognize his overlooked contribution.

National Creativity Day: Founded in 2018 by Hal Croasmun and ScreenwritingU, National Creativity Day celebrates all who create—from writers and artists to coders, designers, and musicians. The day encourages people to keep expressing themselves, take creative risks, and share their work with the world. It’s also a reminder that creativity isn’t limited to the arts—it shows up in problem-solving, innovation, and everyday life.

National E-Bike Day: Lectric eBikes launched National E-Bike Day in 2019 to highlight the growing popularity of electric bicycles. The day encourages sustainable transportation and celebrates the technology behind e-bikes. Coinciding with the company’s anniversary, May 30 recognizes riders who embrace eco-friendly travel while promoting healthier lifestyles and reduced carbon emissions.

National Heat Awareness Day* (Last Friday in May): Created by OSHA and the National Weather Service, this day emphasizes the risks of extreme heat, especially for outdoor workers. It aims to reduce heat-related illnesses and deaths by promoting safety practices like hydration, shade, and rest. The observance encourages employers and the public to take heat seriously, especially as climate change increases the frequency of dangerous heat events.

National Hole in My Bucket Day: This playful day celebrates the traditional children’s song “There’s a Hole in My Bucket,” which dates back to 18th-century Germany. The humorous back-and-forth between Henry and Liza, as Henry tries to fix his leaky bucket, has entertained children for generations. Observed each year on May 30, the day honors classic folk music and invites people to revisit the simple joys of storytelling through song.

National Mint Julep Day: Each year on May 30, this holiday toasts the classic mint julep—a bourbon-based cocktail closely tied to Southern U.S. culture and the Kentucky Derby. With origins traced back to the 1700s, the mint julep was once even prescribed for digestive issues. Traditionally made with bourbon, sugar, crushed ice, and fresh spearmint, it remains a staple of Southern hospitality. A similar celebration takes place on Kentucky Derby Day in early May.

World Multiple Sclerosis Day: Since 2009, the Multiple Sclerosis International Federation has recognized May 30 as World MS Day to raise awareness about this chronic neurological condition. Affecting more than 2.3 million people globally, MS results in damage to the myelin covering nerve cells, often leading to mobility issues and fatigue.
