National & International Days on November 17
Below is a list of 11 national and international days celebrated on November 17, each with a brief explanation.
International Happy Gose Day
International Happy Gose Day was founded in the early 2000s by Ohne Bedenken, a well-known Gose tavern in Leipzig, Germany. The day honors Gose, a historic German sour wheat beer first brewed over a thousand years ago in Goslar, using malted wheat, barley, coriander, and naturally salty river water. After fading from production in the mid-20th century, Gose was revived in the 1980s and has since found new fans worldwide. The celebration invites beer enthusiasts to explore and appreciate the beer’s distinctive, lightly tart, and subtly salted flavor.

International Students’ Day
International Students’ Day honors the courage of students who have stood up for freedom and human rights. The observance originated from the tragic events of 1939, when Nazi forces raided universities in Prague, killing and imprisoning many Czech students. First observed in 1941, it has since become a global symbol of student activism, also remembering later movements such as Greece’s Polytechnic Uprising (1973) and Czechoslovakia’s Velvet Revolution (1989).
National Baklava Day
National Baklava Day celebrates the famous layered pastry enjoyed throughout the Middle East and Mediterranean. Although its founder is unknown, the observance likely arose as a tribute to this time-honored dessert. Baklava combines thin sheets of phyllo dough with nuts and sweet syrup or honey—a recipe refined in the Ottoman Empire and rooted in the Assyrian tradition of the 8th century BCE.
National Butter Day
National Butter Day was founded in 2021 by Dinner Bell Creamery, a cooperative of dairy farm families under Associated Milk Producers Inc. (AMPI). The date was chosen to align with the holiday baking season, recognizing butter’s essential role in kitchens around the world. The day celebrates the work of dairy farmers and buttermakers and reminds us how butter continues to bring richness and flavor to everyday cooking and holiday traditions alike.
National Entrepreneur’s Day
National Entrepreneur’s Day* (Third Tuesday in November) celebrates the people who turn ideas into reality through creativity, courage, and hard work. Founded in 2010 by David Hauser and Siamak Taghaddos, it honors entrepreneurs who take risks, build businesses, and create jobs that strengthen communities. The day often coincides with Global Entrepreneurship Week* (November 17–23, 2025), bringing together innovators, small business owners, and dreamers around the world. Many local events and workshops are held to share advice, spark inspiration, and remind everyone that every successful company starts with someone daring to begin.
National Homemade Bread Day
National Homemade Bread Day invites people to rediscover the tradition of baking bread from scratch. Established in the early 1980s by the National Homemade Bread Committee in Ann Arbor, Michigan, the observance encourages families and home bakers to roll up their sleeves, knead the dough, and enjoy the irresistible aroma of freshly baked bread filling their kitchens.
National Take a Hike Day
National Take a Hike Day, established in 2015 by the American Hiking Society, promotes the physical and mental benefits of spending time outdoors. The day invites people of all ages and abilities to explore trails—from nearby parks to scenic mountain paths—and experience the restorative power of nature.
National Testosterone Awareness Day
National Testosterone Awareness Day, founded by Over 40 Alpha and Funk Roberts Fitness, draws attention to the role testosterone plays in men’s health.

National Unfriend Day, introduced by comedian Jimmy Kimmel in 2010, takes a humorous but thoughtful look at social media habits. It invites people to declutter their online friend lists, keeping their digital spaces authentic and focused on real connections.
National Working Daughters Day
National Working Daughters Day* (Third Tuesday in November) honors the women who juggle careers, family life, and the demanding role of caring for aging parents or relatives. Founded in 2020 by Liz O’Donnell, creator of the Working Daughter community, the observance shines a light on the challenges and strength of those providing unpaid elder care. Held during National Family Caregiver Month, it calls attention to the emotional and financial impact of caregiving and encourages workplaces, families, and communities to recognize and support these women who give so much of themselves every day.
World Prematurity Day
World Prematurity Day began in 2008 through the efforts of several European parent organizations and has since become a global movement supported in over 100 countries.
