Día de los Inocentes, celebrated on December 28th, is a day in many Spanish-speaking countries that commemorates the Holy Innocents, honoring the biblical story of King Herod's decree to kill all male infants in Bethlehem. This day is often marked by playful pranks and jokes, similar to April Fool's Day in the United States. The connection to family customs and values is significant as families come together to share laughter, partake in traditions, and reflect on the importance of innocence and childhood.
