Red Cross Day, or Hari Palang Merah, is observed in Indonesia every September 17, commemorating the establishment of the Indonesian Red Cross Society in 1945. The day marks a significant moment in the country's history, following its independence proclamation on August 17, 1945, and the subsequent need for medical assistance during conflicts. The Indonesian Red Cross Society, which is a national humanitarian organization, provides disaster relief, coordinates blood donations, and implements public health and social programs. Unlike many Muslim-majority countries that use the Red Crescent, Indonesia employs the Red Cross symbol, reflecting its secular nature. The first chairman of the society was Mohammad Hatta, who served as Indonesia's Vice President at the time. The organization remains neutral, assisting all individuals regardless of their religious, political, or ethnic backgrounds.
