The lighting of the Christmas tree is a festive tradition that takes place at the beginning of the holiday season. It usually happens in early December, after the Thanksgiving holiday and before the start of Hanukkah and Christmas. The lighting ceremony is a way to kick off the holiday season and bring people together to celebrate. It often includes carolers, hot cocoa and cider, and Santa Claus himself. It's a special time for families to gather and share the joy of the season.
