Why was May 12 chosen as International Nurses Day?

Florence Nightingale was born.

This is the most obvious reason why May 12 was chosen as International Nurses Day. Florence Nightingale is considered the founder of modern nursing, and her work during the Crimean War showed the world the importance of nursing care. She was born in Florence, Italy on May 12, 1820. Her birthday was chosen as the day to celebrate International Nurses Day as a tribute to her lifelong contributions to the nursing profession and her role in developing it.
