Christmas Jumper Day* (Dates Change, UK 🇬🇧) is a fundraising event led by Save the Children that encourages people to wear festive or humorous Christmas sweaters to support children in need. Although the official 2025 date is Thursday, December 11, many workplaces and schools choose another day that suits their schedule. Participants are usually invited to give a small donation—often £2 for adults and £1 for children—which helps fund Save the Children’s programs providing food, healthcare, and education around the world. Since its launch in 2012, the campaign has become a well-known tradition in the United Kingdom and Ireland.
Holiday Food Drive for Needy Animals Day encourages people to donate food and supplies to animal shelters, rescue groups, and community programs that support pets in need. The day highlights the challenges many animals face during winter, when shelters manage higher demand and limited resources. Donations help ensure animals have enough food, ease financial pressure on shelters so they can focus on medical care and adoption efforts, and provide short-term assistance to families experiencing hardship.
International Mountain Day raises awareness about the importance of mountain ecosystems and the communities that rely on them. Established by the United Nations in 2003, the day encourages learning about the pressures mountains face—from climate change to unsustainable land use—and supports efforts to protect these vital landscapes for future generations.
National App Day celebrates the transformative impact of mobile applications on creativity, innovation, and culture. The observance was founded in 2017 by Platinum Edge Media to highlight how apps have reshaped communication, work, learning, and entertainment in the digital age. The word “app” was even named Word of the Year in 2010 by the American Dialect Society.
National Have a Bagel Day invites people to enjoy bagels in any style they prefer, from classic cream cheese to lox or other toppings. Although the main National Bagel Day falls on January 15, this December observance has become another popular moment to enjoy bagels at any meal of the day.
National Noodle Ring Day celebrates a retro American dish that enjoyed its greatest popularity in the mid-20th century. A noodle ring is made by mixing cooked egg noodles with eggs, cheese, milk, and seasonings, then baking the mixture in a ring mold until firm. After unmolding, the center is filled with a complementary dish such as creamed chicken, fish, vegetables, or meatballs. Versions of the recipe appeared in Pennsylvania Dutch cooking in the 1930s, and it shares similarities with noodle kugel found in Jewish cuisine. The origin of the national day is unknown, but it is thought to have been created by food enthusiasts or brands interested in preserving this nostalgic casserole.

National Stretching Day raises awareness about the benefits of adding stretching to daily routines. Founded in 2022 by Stretch Zone, the observance highlights how flexibility and mobility support overall health. Regular stretching can improve range of motion, ease stiffness, increase circulation, and help prevent injuries. It also supports better posture, reduces muscle tension, and may lessen stress and tension-related headaches.

National Tango Day honors a dance style known worldwide for its expressive music and emotional depth. Founded in Argentina to celebrate Carlos Gardel and Julio De Caro, the observance also highlights tango’s recognition by UNESCO as Intangible Cultural Heritage.
UNICEF Birthday commemorates the founding of UNICEF in 1946, when the United Nations created the agency to support children affected by World War II in Europe and China. Originally called the United Nations International Children’s Emergency Fund, its mission expanded in 1950 to address long-term needs of children and women in developing countries. Today, UNICEF works worldwide to provide healthcare and immunizations, clean water and sanitation, improved nutrition, access to education, and emergency relief during crises.
