National Doctors’ Day is observed in Iran every year on August 23, coinciding with the 1st day of the month of Shahrivar in the Persian calendar. This date commemorates the birthday of Avicenna, a renowned Persian polymath who significantly advanced the field of medicine. Born in 980, Avicenna is best known for his influential work, The Canon of Medicine, completed in 1025, which became a standard medical textbook in Medieval Europe. On this day, Iranian physicians and medical professionals celebrate their contributions to healthcare, reflecting on the legacy of Avicenna, who began his medical career at the age of 16. Iran boasts a robust healthcare system, with a notable proportion of its physicians being women.
