when do the twelve days of christmas start and end

The twelve days of Christmas are traditionally the twelve days from Christmas Day, December 25th, through January 5th, the eve of the Epiphany, also known as Three Kings' Day. The twelve days of Christmas are a celebration of the birth of Jesus Christ and the arrival of the Wise Men to visit the baby Jesus. Each day is marked with special customs and traditions, including gift-giving, feasting, and caroling. It is also a time of spiritual reflection, prayer, and contemplation.
