When the clock strikes 12:00am, all the radio stations here in Mexico are required to play the national anthem. Every station has to do this. If you are in your car and station flipping, you will only be able to find the national anthem. Also on Sunday night around 10:00 or 11:00 pm, all radio stations in the nation are required to feature a program called “La hora nacional” (The national hour). It is a government program that plays only classical music from Mexican composers, reads stories from Mexican authors and features positive news from the Mexican government. The program lasts until 12:00am when the national anthem is played. After, the stations play music and their regular features and announcements.
