National Share the Warmth Day is observed annually on the third Tuesday in October in the United States. This day is dedicated to raising awareness and taking action to ensure that everyone has access to the warmth, comfort, and protection they need. It is led by the national nonprofit organization One Warm Coat, which mobilizes individuals and organizations to donate coats, hold coat drives, and make financial contributions to support those in need. The initiative promotes community involvement and volunteerism, engaging thousands of volunteers each year to collect and distribute coats to children and adults without charge or discrimination. Additionally, One Warm Coat focuses on environmental sustainability by reducing textile waste through its Coat Drive program and collaborating with manufacturers to redistribute unsold outerwear. National Share the Warmth Day emphasizes the importance of compassion and collective action in creating a more equitable world.
