Panamanian Labor Day, or Día del Trabajador, is celebrated annually on May 1st as a national holiday, honoring workers' contributions with parades, events, and a nationwide shutdown of most businesses, government offices, and schools to recognize labor rights and the workforce's importance to the country's development.

This is a mandatory national holiday in Panama. Labor unions organize marches and demonstrations, particularly in Panama City, while smaller towns often focus on family gatherings and rest. This is a day of significance as it celebrates the strength and achievements of the Panamanian working class and advocate for labor rights, stemming from the international May Day movement.
