The Christmas tree is a symbol of the holiday season, and it is typically put up at the beginning of December. Many people choose to put up their tree on the first weekend of December, so that they can enjoy it for the entire month leading up to Christmas. However, the exact timing can vary depending on personal preferences and the activities surrounding the holiday season. Some people prefer to put up their tree early, while others wait until the week before Christmas. Ultimately, the decision is up to you and what works best for your schedule and holiday traditions.
