What Do People Do?

Many events are held around the world on June 14 to mark World Blood Donor Day. These include football matches, concerts and mobile blood donation clinics.

Public Life

World Blood Donor Day is a global observance and not a public holiday.

Background

Despite about 92 million yearly blood donations worldwide, safe blood is constantly on high demand, especially in developing countries.

World Blood Donor Day falls on the birthday of Karl Landsteiner (June 14, 1868). He created the ABO blood group system, which is still used today to ensure the safety of blood transfusions.
