What is Three Kings Day?
Here's the answer:

Three Kings Day is a holiday celebrating the Magi’s visit to Jesus. This holiday is also known as Epiphany.
Three Kings Day occurs on January 6. It is thought to be the day that the Magi visited Jesus. This holiday is celebrated by Orthodox, Catholic, Anglican, and liturgical churches. This means that not every church celebrates Three Kings Day.
The word “epiphany” means “revelation.” It is called Epiphany because this holiday celebrates the revealing of Jesus to the Gentiles. Since the Magi were Gentiles, it represented that the Messiah had come to die for all people, not just the Jews. Some churches also view Epiphany as the celebration of Jesus’ baptism and how He turned water into wine. This is because these events were, yet again, revealing His divinity to all people.
Whether or not you choose to celebrate Three Kings Day is up to you. There is nothing wrong with celebrating this holiday. However, if you do choose to celebrate it, make sure you stay away from any superstitious aspects of this holiday. Some cultures have brought a few not-so biblical ideas into this holiday, and we would be wise to stay away from them.
If you celebrate Three Kings Day in a holy way, then there is nothing to stress about. Worship the Lord and praise His coming into the world. It is good to continue to celebrate the Lord, even after Christmas. Three Kings Day is the perfect time to do this.

Bible Truth
"When they saw the star, they were filled with joy. The Wise Men went to the house. There they saw the child with his mother Mary. They bowed down and worshiped him. Then they opened their treasures. They gave him gold, frankincense and myrrh. But God warned them in a dream not to go back to Herod. So they returned to their country on a different road" (Matthew 2:10–12).
"One person considers one day to be more holy than another. Another person thinks all days are the same. Each of them should be absolutely sure in their own mind" (Romans 14:5).
"So eat and drink and do everything else for the glory of God" (1 Corinthians 10:31).
