Great British Spring Clean
Great British Spring Clean* (March 13– March 29, 2026) is the UK’s largest mass-action environmental campaign. Keep Britain Tidy, an environmental charity founded in 1954, launched the event in 1989 to combat litter and pollution across the UK. Since then, millions of volunteers have taken part in litter-picking efforts.
International Every Girl Wins Day

Grant writers, managers, administrators, and consultants work to drive social impact by supporting research, education, and community initiatives.
International Riesling Day
International Riesling Day celebrates one of the world’s most beloved white wine grapes. The date honors the earliest documented record of the Riesling grape, found in a German cellar log from Rüsselsheim dated March 13, 1435. Officially established in 2019 by the German Wine Institute, the day highlights both the grape’s heritage and global popularity. Riesling is prized for being terroir-expressive, meaning its flavor shifts dramatically based on where it’s grown.
🍇 Did you know there are over 70 wine-themed days celebrated throughout the year?
International Smart & Sexy Day
International Smart & Sexy Day has been organized by ACDN since 2012 to help women build confidence and develop skills for employment. Celebrated during Women’s History Month, the day features workshops and online events that empower women to achieve professional success.
Intrauterine Growth Restriction Awareness Day
Intrauterine Growth Restriction Awareness Day raises awareness about intrauterine growth restriction (IUGR), a condition that affects fetal development due to oxygen deprivation, poor nutrition, or medical complications. The observance educates the public on early detection and treatment while offering support for affected families.
National Chicken Noodle Soup Day
National Chicken Noodle Soup Day traces its roots to a happy accident. When Campbell’s launched “Noodle with Chicken” soup in 1934, a radio personality accidentally flipped the words on air, and the name “Chicken Noodle” stuck simply because it sounded better. The soup has long earned a reputation as cold-season comfort food, backed by research suggesting mild anti-inflammatory effects and a broth that replenishes fluids lost when sick.
National Coconut Torte Day
National Coconut Torte Day celebrates a dessert beloved in the American South, born from the Central and Eastern European tradition of the torte, a word that simply means cake in German.
National Dermatologist Day
National Dermatologist Day was founded by EltaMD Skin Care in 2024 to honor board-certified dermatologists and the extensive training they undergo to treat skin, hair, and nail conditions. The day serves as a tribute to their vital role in keeping patients healthy.
National Earmuff Day
National Earmuff Day marks the anniversary of Chester Greenwood’s 1877 patent for earmuffs. Greenwood, a young inventor from Farmington, Maine, created this simple but effective solution for keeping ears warm in cold weather, and his invention went on to generate jobs in his hometown. The day honors how a straightforward idea can leave a lasting impact, and Greenwood is celebrated again each year on Chester Greenwood Day, held on the first Saturday of December.
National Ginger Ale Day
National Ginger Ale Day was created in 2011 by Michigan Expats to honor Vernors Ginger Ale, a Detroit-born soft drink beloved for its spicy-sweet flavor. The date reflects Detroit’s 313 area code, and though the holiday originally focused on Vernors specifically, food publications gradually expanded its scope by 2016 to encompass all ginger ale brands nationwide.
National Good Samaritan Day
National Good Samaritan Day, also known as Good Samaritan Involvement Day, honors those who selflessly help others in need. The date marks the 1964 murder of Kitty Genovese in Queens, New York, a tragedy that shocked the public after reports that bystanders failed to intervene, ultimately spurring the creation of emergency services systems and inspiring greater awareness of individual responsibility to help others.
