Cinco de Marcho is celebrated annually on March 5, just 12 days before St. Patrick’s Day. This made-up holiday, inspired by the Mexican holiday Cinco de Mayo, serves as a lighthearted occasion for those who are not regular drinkers to prepare for the drinking festivities associated with St. Patrick’s Day. The holiday encourages participants to drink safely and in moderation, emphasizing the importance of finding one's limits rather than excessive drinking. The concept was created by an individual known as Carlos Fantastico, who envisioned a celebration that blends elements of both Mexican and Irish cultures. Celebrators often use this day as a way to gradually build their alcohol tolerance in anticipation of the upcoming holiday parties.
