National Homeless Persons’ Remembrance Day, also known as National Homeless Persons’ Memorial Day, is observed in the United States every December 21. This day honors individuals who have died while homeless over the past year and takes place on the winter solstice, the longest night of the year, to highlight the struggles of homeless people. The observance began in 1990 and is supported by organizations such as the National Alliance to End Homelessness and the National Coalition of the Homeless, which coordinate memorial events across the country. Typical customs include candlelight vigils, graveside services, performances, and silent marches. The day aims to encourage public support for homeless individuals and families, with anyone able to host or participate in local events. The principal causes of homelessness are identified as a lack of affordable housing and insufficient-paying jobs, with at least 20 homeless people dying each day in the U.S. from various causes.
