What is Rare Disease Day?



Established in 2008 by EURORDIS and its Council of National Alliances, Rare Disease Day is a global movement with the goal of spreading awareness of rare diseases, working towards equity in social opportunity, healthcare, and access to diagnosis and therapies for people living with a rare disease. Rare Disease Day has assisted in building international diverse rare disease communities who have united in their efforts to advocate for those with rare diseases.


Rare Disease Day is observed every year on 28 February (or 29 in leap years)—the rarest day of the year.
