National Hispanic Heritage Month honors the culture, heritage, and contributions of Hispanic Americans each year.
The day of September 15 is significant because it is the anniversary of independence for Central American countries Costa Rica, El Salvador, Guatemala, Honduras and Nicaragua. In addition, Mexico and Chile celebrate their independence days on September 16 and September 18, respectively.

The independence of Central America is called the emancipatory process by the current countries of Guatemala, Honduras, El Salvador, Nicaragua and Costa Rica, which, through the signing of the Central American Independence Act on September 15, 1821, break ties with the Spanish Empire. Unlike the other American countries, this was a relatively peaceful process.

Another celebration is the Independence of Mexico. The question of many people is when is the independence of Mexico?
Well a lot of Americans are confused about it. Every year Americans celebrate 5 de Mayo thinking that’s the day of the independence of Mexico, but the real date is September 16th.
The Independence of Mexico was a political and social process that took place over eleven years. It began on September 16, 1810 and ended on September 27, 1821 by liberating Mexico, formerly the Viceroyalty of New Spain, from Spanish rule.

The process of Mexican independence began with the Grito de Dolores, a call made by the priest Miguel Hidalgo y Costilla to his parishioners to rebel against the Viceroyalty of New Spain, and ended with the signing of the Treaties of Córdoba, a document in the which Mexico was recognized as an independent nation.
Anyone can celebrate National Hispanic Heritage Month and show their appreciation for the Hispanic and Latin Americans by doing things like supporting Hispanic/Latino owned businesses, reading books by authors of Hispanic/Latino origin, watching movies about the culture, going to local events that celebrate the contributions of Hispanic and Latino people have made to U.S. society.
