Why do spanish children receive their gifts?

Spanish children receive their gifts primarily on January 6th, during the celebration of Epiphany, known as "Día de Reyes" (Three Kings' Day). This tradition commemorates the arrival of the Three Wise Men who brought gifts to the baby Jesus. On the night of January 5th, children leave their shoes out, often filled with hay or grass for the Kings' camels, and in return, they find presents the next morning. This custom emphasizes the significance of the Three Kings in Spanish culture and is a cherished part of the holiday season.
