This page collects all the officially recognized awareness days, weeks, and months dedicated to autoimmune diseases, autoinflammatory conditions, and chronic illness — so you always know when your community is speaking and how to join in. Whether you're living with lupus, rheumatoid arthritis, Crohn's disease, or any of the dozens of other conditions covered here, these dates are yours.
