About World Blood Donor Day
World Blood Donor Day arrives every year on June 14 to thank the volunteers whose donations keep hospitals running and to encourage millions more people to roll up a sleeve. Safe blood is one of those quiet miracles of modern medicine: it arrives in emergency rooms after crashes, supports mothers during difficult deliveries, and sustains cancer patients through treatment, yet it cannot be manufactured in any laboratory. Every unit has to come from a person who chose to give it.
The day is organized by the World Health Organization together with partners such as the International Federation of Red Cross and Red Crescent Societies. Each year has a theme, a host country, and a global campaign that highlights gaps in supply, since many low-income countries still collect far fewer units than they need. Whether you give blood twice a year or have never donated, June 14 is a friendly reminder that one hour of your time can save several lives.

History of World Blood Donor Day
The date honors Karl Landsteiner, the Austrian-born scientist who discovered the ABO blood group system and was born on June 14, 1868. His work made safe transfusions possible by explaining why some donations succeed while others can be fatal. The World Health Assembly designated World Blood Donor Day in 2004, and it has been marked every year since, rotating its global event between host countries from South Africa to South Korea. The observance grew out of decades of work by blood services and the Red Cross movement to professionalize donation and improve screening. Today more than 100 countries participate with blood drives, award ceremonies for repeat donors, and public education campaigns about eligibility, and the day anchors a larger WHO strategy for voluntary, unpaid donation.
