About Rare Disease Day
Rare Disease Day is the global day of awareness for the roughly 300 million people worldwide living with a rare condition. Held on the last day of February, it brings together patients, families, researchers, and advocacy organizations in more than 100 countries to demand visibility for conditions that most people have never heard of. Individually, a rare disease affects a small number of patients; collectively, rare diseases touch one in twenty people at some point in their lives.
The day's symbol is the zebra, a nod to the medical school saying that when you hear hoofbeats, think horses, not zebras. For patients with rare conditions, thinking zebras is the difference between years of misdiagnosis and getting real answers. Events range from policy conferences and hospital open houses to fundraising walks, school activities, and buildings lit up in the movement's colors. The campaign presses for equitable access to diagnosis, treatment, and care, and for research funding that rare conditions rarely attract on their own.

History of Rare Disease Day
Rare Disease Day was launched by EURORDIS, the European Organization for Rare Diseases, together with its national alliance partners, and the first edition was held on February 29, 2008, the rarest date of the calendar year. The choice of the last day of February was deliberate: in leap years the day falls on February 29, a date that exists only once every four years, mirroring how rare the conditions are. The campaign grew steadily across Europe and then worldwide; the United States joined in 2009 with coordination by the National Organization for Rare Disorders. Since then the day has been endorsed by health ministries, patient organizations, and institutions across more than 100 countries, and each year carries a specific theme, such as equity in diagnosis or bridging health inequalities. Landmarks around the world light up in the campaign's colors, and policymakers are lobbied to support rare disease research and care.

Frequently Asked Questions
- When is Rare Disease Day?
- It is held on the last day of February, so the date changes each year: usually February 28, but in leap years like 2028 it falls on February 29. In 2026, Rare Disease Day takes place on February 28.
- Is Rare Disease Day a public holiday?
- No. It is an international awareness campaign, not a public holiday; offices and schools stay open, and most activities are voluntary events.
- How is Rare Disease Day observed?
- Patient groups observe the day with conferences, awareness walks, school lessons, and light-up landmark events, while individuals observe it by wearing zebra stripes and sharing accurate information about rare conditions.
- Why is the zebra the symbol of Rare Disease Day?
- It comes from the medical school saying that when you hear hoofbeats, you should think horses, not zebras. The rare disease community flipped the phrase, arguing that doctors should also consider zebras, the unusual diagnoses, when symptoms do not fit the common ones.
