Irish culture has many superstitions that originated from a mix of Christianity, folklore, and stories passed down through generations. Some of the more common Irish superstitions include beliefs that a person's luck is determined at birth, finding a horseshoe can bring lifelong luck if discovered on the way home, and black cats crossing one's path can signify either good or bad luck depending on whether the cat makes eye contact. Reciting a poem about the days of the week is also thought to bring marital luck.
