When is World Blood Donor Day celebrated?

World Blood Donor Day is celebrated on June 14 each year. This day holds significant importance as it raises awareness about the need for safe blood and blood products, and it acknowledges and appreciates the contributions of voluntary unpaid blood donors. The date of June 14 is particularly symbolic as it is the birthday of Karl Landsteiner, the scientist who discovered the ABO blood group system. By celebrating on this date, the event emphasizes the importance of voluntary blood donation in saving lives and improving health outcomes. Additionally, World Blood Donor Day serves as a global call to action to encourage more people to become regular, unpaid blood donors, thereby contributing to a sustainable blood supply for those in need.
