History of Wear A Hat Day

The holiday was launched in 2010 by the charity Brain Tumour Research in the United Kingdom. It was created to provide a simple, fun, and inclusive way for the public to support a serious medical cause. The founders recognized that brain tumors kill more children and adults under the age of 40 than any other cancer, yet the disease historically received a minimal percentage of national cancer research spending. The “hat” theme was chosen as a visible and lighthearted symbol of protection for the head and brain. ¹

Since its first occurrence, the event has grown into a massive national movement, raising millions of pounds for research centers of excellence. Celebrities, schools, and major corporations have joined the campaign, often creating “hattastic” challenges and world-record attempts. The initiative has expanded its reach internationally, inspiring similar awareness events in other countries where supporters don diverse headgear to signal their commitment to finding a cure for all types of brain tumors.

Why is Wear A Hat Day important?

This day is vital for drawing attention to the significant funding gap in neuro-oncology research. While many forms of cancer have seen vast improvements in survival rates due to extensive study, brain tumor outcomes have remained relatively stagnant for decades. By participating in Wear A Hat Day, the public helps generate the financial resources necessary to support scientists and clinicians who are working on life-saving treatments and earlier diagnostic tools.

Beyond the financial aspect, the day provides a powerful sense of community for those living with a diagnosis and for families who have lost loved ones. Seeing a sea of hats in workplaces and schools reduces the isolation often felt by patients and encourages open conversations about the realities of the disease. It turns a month of somber awareness into a day of hope and collective action, demonstrating that even a small, quirky gesture can contribute to a much larger global fight against cancer.

• It raises critical funds for brain tumor research and clinical trials.
• The day highlights the disproportionate lack of funding for brain cancer.

• It unites diverse communities through a simple and fun activity.

How to Observe Wear A Hat Day

The most direct way to participate is by wearing a hat of your choice—whether it is a simple beanie, a formal top hat, or a homemade creation—and making a donation to a brain tumor charity. Many schools and offices organize “Hat Day” events where everyone pays a small fee to wear their headgear for the duration of the day. You can also host a hat-themed tea party or a “Best Hat” competition to encourage larger groups to get involved and contribute to the fundraising goal.

Digital participation is another key element of the modern observance. Supporters often take “hat selfies” and share them on social media platforms with the official campaign hashtags to spread awareness beyond their immediate physical location. You can also purchase official merchandise, such as wristbands or pin badges, to show your support throughout the year. For those who want to do more, organizing a sponsored “hat-a-thon” or a creative workshop to decorate hats can help maximize the impact of the day.

• Don your favorite piece of headwear and wear it all day long.
• Organize a hat-themed bake sale or coffee morning for your coworkers.
• Share a photo of your hat on social media to raise awareness online.
• Make a direct donation to a brain tumor research organization.
• Host a competition for the most creative or wacky hat in your group.
