José Yulo Day is observed in Calamba, Laguna, on September 24 each year, commemorating the birth of José Yulo, a prominent Philippine lawyer and politician born in 1894. The day highlights Yulo's significant contributions, including his roles as Chief Justice of the Supreme Court and Speaker of the National Assembly. Yulo began his legal career after studying law at the University of the Philippines and later became known as one of the best corporate lawyers in the country. His political journey included serving as Secretary of Justice and participating in the establishment of the unicameral National Assembly. Despite challenges during the Japanese occupation, Yulo maintained judicial integrity and continued to influence Philippine politics after World War II. The holiday serves to honor his legacy and is distinct from Carlos Yulo Day, celebrated in Manila on August 4.
