June 1st – Día de la Marina ( Mexican Navy Day )
This day is celebrated in all coastal towns, with naval parades and fireworks.  Mexican Navy Day is an official Mexican holiday. The date that Navy Day is celebrated was determined by the fact that on 01 June 1917, for the first time a Mexican merchant vessel, the steamer “Tabasco”,  left the port of Veracruz. The entire crew was composed exclusively of native born Mexicans and captained by Captain Don Rafael H. Izaguirre Castanyares. The correct name of the Mexican Navy is Armada de México.
