Moebius Syndrome Awareness Day is an annual event celebrated globally each year on January 24th — the birth date of Professor Paul Julius Moebius, the doctor who first diagnosed the condition in 1888.

In 2011, Moebius Syndrome Awareness Day was started by the Many Faces of Moebius Syndrome and has been embraced globally by other organizations that support efforts to raise awareness. The Moebius Syndrome Foundation celebrates #MSAD by sharing information about Moebius syndrome, offering financial support and resources to approved events, encouraging people to wear purple, and raising awareness through various means and channels.
