"Labor Day was first observed in the country on May 1, 1903, when some 100,000 workers marched to Malaca\u00F1ang. The country&amp;#039;s first official celebration of Labor Day, however, was 10 years later, on May 1, 1913, when 36 labor unions convened a labor congress at Cine Oriente on CM Recto Street, then known as Azcarraga, in Manila.
