Flag-flying days in Mexico

In Article 18 of the Law on the National Arms, Flag, and Anthem (Ley Sobre El Escudo, la Bandera y el Himno Nacionales) there is a listing of dates that the Mexican flag is flown by all branches of government. Civilians are also encouraged to display the national flag on these days.
