Brown-Bag-It Thursday* (Third Thursday in May) encourages people to pack their own lunch for school or work as a cost-effective and health-conscious habit.

International Tea Day
International Tea Day was first celebrated informally in tea-producing countries starting in 2005 and later became official in 2020 when the United Nations adopted May 21 as International Tea Day. The goal is to recognize tea’s cultural and economic importance while promoting sustainable production and consumption. Tea remains one of the most consumed beverages in the world, and this day highlights its role in supporting livelihoods and reducing hunger.
National American Red Cross Founder’s Day
National American Red Cross Founder’s Day honors the founding of the American Red Cross and the work of Clara Barton, who brought the idea of the organization to the U.S. after working with the International Red Cross in Europe. She officially founded the American Red Cross in 1881, and this day recognizes her humanitarian legacy and the organization’s ongoing commitment to disaster relief and emergency response.
National Apéritif Day
National Apéritif Day* (Third Thursday in May) was introduced in 2013 by French aperitif producer Maison Lillet. It celebrates the tradition of enjoying a light drink before a meal. The word “apéritif” comes from the Latin “aperire,” meaning “to open,” reflecting the idea of preparing the palate for food. From vermouth and dry sherry to gin and Dubonnet, aperitifs have a rich history across Europe and beyond. The day honors their role in both social gatherings and culinary culture.
National Memo Day
National Memo Day was created in 1989 by KMJI Majic Radio 100 FM in Denver, Colorado. It acknowledges the role of memos in everyday communication, especially in the workplace.

Today’s observance also reflects on how memos have evolved—now often shared through email, apps, and social media.
National Notebook Day
National Notebook Day* (Third Thursday in May) was first celebrated in 2016. It promotes the value of journaling and expressive writing.

National Strawberries and Cream Day celebrates the pairing of fresh strawberries and whipped cream—just in time for peak strawberry season.

It encourages exploring relief options and highlights technology and support systems available to help manage this often-overlooked issue.
National Talk Like Yoda Day
National Talk Like Yoda Day was inspired by the Jedi Master from The Empire Strikes Back. This fan-driven holiday emerged in the early 2000s to honor Yoda’s first film appearance in 1980. Known for his unusual sentence structure and timeless wisdom, Yoda remains a favorite character in the Star Wars universe. Fans celebrate by mimicking his speech and sharing quotes in his distinctive voice.

World Day for Cultural Diversity for Dialogue and Development
World Day for Cultural Diversity for Dialogue and Development was declared by the United Nations in 2002 to promote understanding and respect among different cultures.

Often shortened to “Diversity Day,” it highlights how cultural exchange contributes to peace and development.
World Fish Migration Day

This international event raises awareness of the need for free-flowing rivers and healthy migratory fish populations. Starting in 2025, the event will be led by VENAE in the Netherlands.
