Epiphany, also known as Three Kings' Day, is a significant religious holiday in Slovakia, observed annually on January 6th. It marks the visit of the three Wise Men - Melchior, Caspar, and Balthasar - to the newborn Jesus Christ in Bethlehem. This holiday signals the end of the Christmas season and the Twelve Days of Christmas in the Slovakian tradition.

Slovakians celebrate Epiphany in a special manner. The holiday is marked by attending a Mass, where people are blessed with 'holy water'. This holy water is then taken home to bless their homes, protecting them from evil and misfortune. Additionally, the initials of the Three Kings are traditionally written on the doors of households with a blessed chalk this day, symbolizing the blessing of houses. It's a customary practice for families to leave their Christmas decor until this day, as Epiphany is considered the last day of the Christmas season.

Epiphany is a public holiday in Slovakia, meaning that schools and most businesses are closed. Many cities and towns conduct Epiphany processions, where three young boys dressed as the Wise Men lead the procession, followed by other children dressed as angels and shepherds. This procession, along with traditional songs, represents the journey of the Wise Men to see baby Jesus. This holiday is an important cultural event, showcasing the deep-rooted Christian faith and traditions of Slovakians.
