World Blood Donor Day: 14 June

World Blood Donor Day is day dedicated to "thanking and celebrating voluntary non-remunerated blood donors". It occurs on June 14, the birthday of Karl Landsteiner, the creator of the ABO blood group system, for which he won the Nobel Prize. The first day was held in 2005.

The theme of 2012 world blood donor day campaign-"every blood donor is a hero" focuses on the idea that every one of us can become a hero by giving blood.

One of the main goals of the World Blood Donor Day is to ensure the availability of 'safe blood' for transfusion.
