While I appreciate your, and from the look of it, about 50% of other respondents issue with the topic title, the question's not really asking you about any mexican festivals, regardless of their spelling or purpose. The date is just a trigger for the topic, not the topic iteself.

"Do you have a festival that celebrates the statistically unlikely outcome of a battle in your country?" might have had fewer respondents ;)
