What is martes 13?

Martes 13 is the Spanish term for Tuesday the 13th. It is considered an unlucky day in many cultures, similar to Friday the 13th in English-speaking countries. In Latin American and Spanish cultures, it is believed to be particularly unlucky and some people avoid scheduling important events or making big decisions on this day. The origin of this superstition is not clear, but it is believed to have a connection with Christianity, as Judas Iscariot was the 13th person at the Last Supper, which took place on a Thursday. However, the belief in the unluckiness of Tuesday the 13th predates Christianity and can be traced back to ancient civilizations. Some people even believe that accidents and bad luck are more likely to occur on this day.
