What Is Hispanic Heritage Month and When Is It Observed in the United States?

Hispanic Heritage Month in the United States runs every year from September 15 to October 15. It is a month-long observance dedicated to celebrating the histories, cultures, and contributions of Hispanic and Latino communities in the U.S. The mid-month start date is deliberate: September 15 is the independence anniversary of several Latin American countries, so the period links a U.S. cultural observance to Latin American history—including Mexico's own independence, which falls on September 16.

When and why it starts on September 15

The observance begins on September 15 rather than the first of the month because that date marks the independence day of Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua. Mexico celebrates its independence on September 16, and Chile on September 18. By starting on the 15th, the month covers these anniversaries within a single commemorative window.

How it began

Hispanic Heritage Month grew out of a shorter observance. It started as Hispanic Heritage Week, proclaimed by President Lyndon B. Johnson in 1968, and was later expanded to a full month. President Ronald Reagan extended it in 1988, and it became law that same year, establishing the September 15 to October 15 period that is still observed today.

What it celebrates

The month recognizes the culture and contributions of Americans whose ancestry traces to Spain, Mexico, the Caribbean, and Central and South America. It is observed across the U.S. through:

• Educational programs and school lessons on Hispanic and Latino history
• Cultural events featuring music, food, and traditions
• Public recognition of Hispanic and Latino figures in arts, science, business, and public life
• Library and museum exhibitions

How it connects to Mexican history

Because the observance overlaps with Mexico's Independence Day on September 16, the month is a natural entry point for learning about Mexican history and traditions. Topics often explored during this period include:

• Mexican Independence Day (16 de Septiembre) and the "El Grito" ceremony
• Cinco de Mayo, which commemorates the Battle of Puebla and is not Mexico's Independence Day
• Mexican heroes such as Miguel Hidalgo, known as the Father of Mexican Independence, and General Ignacio Zaragoza, a Cinco de Mayo hero
• Mexican food traditions, including dishes like Tres Leches Cake (Pastel de las Tres Leches)

Common points of confusion

• Hispanic Heritage Month is not a single-country holiday. It covers many countries and communities, not just Mexico.
• Cinco de Mayo and Mexico's Independence Day are different events. Cinco de Mayo marks the 1862 Battle of Puebla; Independence Day marks the start of the independence movement in 1810.
• The month starts mid-September, not on September 1. This is tied directly to the independence anniversaries it overlaps.
