Dr. José Gregorio Hernández Day is observed in Venezuela every October 26 to commemorate the birthday of the esteemed physician José Gregorio Hernández Cisneros, who was born on this date in 1864. The holiday celebrates his significant contributions to Venezuelan medicine, including his role in modernizing the healthcare system and his dedication to treating the poor. Hernández studied medicine at the Central University of Venezuela and furthered his education in Europe, where he introduced the microscope to the country. After his death in 1919, he became known for miraculous healings, leading to his beatification by the Catholic Church in 2021. In 2011, the Venezuelan government declared his birthday a national holiday, which is a bank holiday, meaning it is a non-working day for the banking sector. The observance is typically moved to the nearest Monday if it falls on a weekend, creating a three-day weekend for the public.
