Two Mexican September-ish dates
Cinco de Mayo vs Mexican Independence Day - what the US thinks Mexico celebrates, vs what Mexico actually celebrates
Cinco de Mayo (May 5) and Mexican Independence Day (September 16) are very different holidays, in very different months, with very different histories, and the US celebration of Cinco de Mayo is much larger than the Mexican one. Side-by-side comparison of the two dates, their actual observance, and the surprising commercial footprint of the US Cinco de Mayo.
Cinco de Mayo and Mexican Independence Day are very different holidays, in very different months, with very different histories, and the US celebration of Cinco de Mayo is much larger than the Mexican one. Many Americans conflate the two; they are unrelated.

Different wars, different holidays
The two holidays commemorate wars against two different foreign powers in two different centuries. Cinco de Mayo (May 5, 1862) commemorates the Mexican militia's unexpected defeat of a larger French Imperial force at the Battle of Puebla during the French intervention in Mexico (1861-1867). The French eventually won the war and installed Maximilian I as Emperor of Mexico; he was deposed and executed in 1867. Cinco de Mayo is a minor date in Mexican history. Mexican Independence Day (September 16, 1810) commemorates Father Miguel Hidalgo's Grito de Dolores, which started the 11-year Mexican War of Independence from Spain. The war ended in 1821 with Mexican independence. This is the foundational national holiday.
Mexican observance vs US observance
The two holidays have completely different observance footprints in Mexico vs the US. In Mexico, Cinco de Mayo is a normal working day; only the state of Puebla commemorates it officially. In the US, Cinco de Mayo is the major Mexican-themed commercial event, with annual beer sales estimated at $1+ billion and large events in cities with significant Mexican-American populations. Mexican Independence Day is the inverse: the major Mexican federal holiday with a national military parade and the Grito reenactment on the night of September 15; in the US, it has a smaller observance among Mexican-American communities. The US celebration of Cinco de Mayo and the Mexican celebration of Independence Day both reflect local cultural priorities, not a shared calendar.
Date logic
Both holidays are on fixed Gregorian dates. Cinco de Mayo is always May 5. Mexican Independence Day is always September 16, with the night-before (September 15) being the Grito de Dolores reenactment. In 2026, Cinco de Mayo is on Tuesday, May 5; Mexican Independence Day is on Wednesday, September 16, with the eve celebration on Tuesday, September 15. The two holidays are 134 days apart on the calendar.
Cultural weight
In Mexico, Mexican Independence Day is the larger commercial and social event. The Mexican government spends several hundred million pesos on the national celebration, including the military parade on the morning of September 16 and the Grito reenactment on the night of September 15 (led by the President from the balcony of the National Palace). In the US, Cinco de Mayo is the larger commercial event; the National Restaurant Association estimates it's one of the top 10 bar-and-restaurant days of the US calendar year, with particularly large volumes of beer and tequila sales.
Contestation
Cinco de Mayo in the US faces ongoing debate over cultural appropriation, with critics arguing that the holiday has been reduced to a beer-and-margarita commercial event disconnected from its original Mexican context. Some Mexican community organizations have promoted "Cinco de Mayo, not Cervaza de Mayo" events emphasizing the holiday's anti-colonial history. Mexican Independence Day faces a different contestation: a reframing of the Grito narrative to include the role of Indigenous and Afro-Mexican communities in the independence movement, with a more critical reading of Hidalgo and his legacy.
What you can do with this
For a 2026 calendar: Cinco de Mayo is Tuesday, May 5; Mexican Independence Day is Wednesday, September 16. For a Mexican cultural-awareness program, the two holidays offer paired opportunities: Cinco de Mayo in May as a community event, and Independence Day in September as a heritage-education event. For a school unit on the difference between commemoration and celebration, the two holidays are an ideal case study.
