National Christmas Tree Day is observed in the United States every December 8 and is an unofficial holiday created by Jace Shoemaker-Galloway. The day encourages people to select and decorate their Christmas trees, marking the beginning of the Christmas season for those who prefer to wait until after Thanksgiving. The tradition of decorating evergreen trees can be traced back to 15th-century Germany, Estonia, and Latvia, evolving over the centuries from religious practices to a more secular celebration. In Canada, National Christmas Tree Day is celebrated on the first Saturday of December, initiated by the Canadian Christmas Tree Growers Association to promote the purchase and decoration of Christmas trees while highlighting the environmental benefits of tree farms. Common customs include setting up trees adorned with ornaments, tinsel, and lights, and sharing photos on social media using hashtags like #ChristmasTreeDay.
