World AIDS Day,and its related observances:

Day Without Art

International day dedicated to raising awareness of HIV/AIDS and commemorating those affected by the disease.
World AIDS Day, observed on December 1 and first established by the World Health Organization in 1988, unites people worldwide in the fight against HIV/AIDS. The day aims to show support for those living with HIV, remember those who have died, and promote prevention and treatment efforts. The related 'Day Without Art' initiative began in 1989 to highlight the impact of the AIDS crisis on the arts community, with museums and galleries presenting alternative programming or closing in solidarity. Activities on World AIDS Day include educational campaigns, memorial ceremonies, art exhibitions, and fundraising events. The observance underscores the ongoing importance of research, care, and reducing stigma around HIV/AIDS.
