International Day of the Zebra is observed worldwide every January 31 to raise awareness of Ehlers-Danlos syndrome (EDS) and hypermobility spectrum disorders (HSD). The day was named after the medical slang term "zebra," which refers to rare medical diagnoses, highlighting the uniqueness of EDS as a condition with varied symptoms among patients. Activities on this day include sharing personal experiences related to EDS and HSD, educating others about these disorders, and showing support by wearing zebra print awareness ribbons. The observance encourages individuals to use the hashtag #DayOfTheZebra on social media to promote understanding. Interestingly, some people mistakenly celebrate this day as a conservation awareness day for actual zebras, which is referred to as International Zebra Day.
