Teachers' Day is observed in Argentina every September 11 to honor Domingo Faustino Sarmiento, the seventh president of the country and a significant figure in education reform. Sarmiento, who focused on improving education for children and women, implemented the Statutory Law of Public Education while serving as governor of San Juan and later established numerous educational institutions during his presidency. His efforts allowed 100,000 children to attend school and contributed to the development of the educational system in Argentina. The date also marks the anniversary of Sarmiento's death in 1888, which was designated as Teachers' Day in the 1940s to commemorate his contributions to education.
