Traditions and festivities in Aguascalientes are an important and pervasive part of the city’s identity.  

The most popular and important celebration is the San Marcos Fair held every April 25th and considered the "La Feria De Mexico" (the Mexican Fair). This is because of its large size,  number of shows, and activities that take place. The fair commemorates San Marcos Evangelista (St. Mark the Evangelist), the patron saint of the Aguascalientes neighborhood with that name.

In August, the city celebrates the Pilgrimage to Our Lady of the Assumption. On September 15, the Independence Day parade is held. From the end of October to November 2, the Festival of Skulls pays homage to José Guadalupe Posada. And the Guava Fair, held in December, is dedicated to the fruit that grows so well here because of the warm weather.

Each of these occasions lets the city display its pride in its rich cultural, culinary, and craft heritage to visitors.
