About World Blood Donor Day
World Blood Donor Day is observed on 14 June to thank voluntary, unpaid blood donors and to raise awareness of the need for safe blood and blood products.
The day sits at the intersection of donor recognition and health-system preparedness: reliable blood services depend on safe collection, testing, processing, storage and appropriate clinical use.
Why World Blood Donor Day matters
The observance celebrates donors, but it should not pressure people to donate or imply that everyone is eligible. Blood-donation criteria differ by jurisdiction and can depend on health, medications, travel and other factors.
A responsible page points prospective donors to their official blood service for current eligibility rules and appointment information.

The first World Blood Donor Day was observed on 14 June 2004. WHO records that the event was celebrated internationally before the observance had been established as an annual World Health Assembly day.
