The Epiphany, or "Little Christmas", is observed on January 6th in many Christian churches. This day has come to be known as the "King's Day".
Since the 300's, the day has honored the meeting of the three wise men with the infant Jesus. King Cakes became part of the celebration to symbolize the finding of the baby Jesus.
Traditionally King Cakes are oval to symbolize the unity of all Christians. The Mardi Gras Season begins on "Twelfth Night" (January 6th) and is expressed on King Cakes by using the carnival colors of green, yellow and purple. King Cake Season ends on Mardi Gras ("Fat Tuesday") which is the day before the Lenten season begins.
After a King Cake is cut and served, the guest whose slice contains the "baby" which has been hidden in the cake is then obligated to bring a King Cake to the next celebration.
