National Donor Day is observed in Russia every April 20 to commemorate the first successful blood transfusion in the country, which occurred on April 20, 1832, performed by obstetrician Andrey Wolf. The day primarily honors blood donors who voluntarily contribute to community blood supplies, as well as the medical professionals involved in blood collection and transfusions. In Russia, blood donors receive paid time off from work and a free meal after donating. Those who donate whole blood 40 times or plasma 60 times are awarded the title of Honorary Donor of Russia, granting them certain privileges. The observance highlights the importance of blood donation and recognizes the contributions of healthcare workers in this vital process.
