World Blood Donor Day is observed annually on June 14 to raise awareness about the importance of blood donation and to thank voluntary blood donors for their life-saving contributions. This day was established by the World Health Organization (WHO) in 2004 and coincides with the birth anniversary of Karl Landsteiner, the Nobel Prize-winning scientist who discovered the ABO blood group system. The event emphasizes the need for safe blood supplies and encourages more people to donate blood regularly to ensure hospitals and healthcare facilities are adequately stocked.

Each year, World Blood Donor Day features a specific theme to highlight different aspects of blood donation. The campaign aims to promote community involvement in health systems and inspire individuals to become repeat donors. Blood donation plays a vital role in saving lives during emergencies, surgeries, and treatments for various medical conditions. By celebrating this day, WHO and other health organizations stress the importance of voluntary, unpaid blood donors in building a reliable and safe blood supply worldwide.
