The second day of Christmas is December 26th. It marks the first day after Christmas and is traditionally a day of rest and relaxation. It's a time to reflect on the holiday season and enjoy the gifts that were received. Some families may choose to spend time together playing board games, watching movies, or simply spending quality time with one another. It's also a day when many people return to work or school after the holiday break. For those who celebrate the Twelve Days of Christmas, it's the second day in a sequence of twelve days of celebration and festivities.
