From the World AIDS Campaingn Website:
World AIDS Day is celebrated on December 1 each year around the world. It has become one of the most recognised international health days and a key opportunity to raise awareness, commemorate those who have passed on, and celebrate victories such as increased access to treatment and prevention services.

From The Body:
Over the years, World AIDS Day has become a global phenomenon that has prompted massive media coverage, raised awareness, encouraged people to get involved and helped amplify the voices of those living with HIV/AIDS. Every Dec. 1 for the past 22 years, humanity has taken 24 hours to commemorate those who have died, acknowledge those who live and those who fight on the frontlines of the battle against HIV, and ponder what it will take to eliminate the virus once and for all.
