This holiday is observed nationally on the fourth Tuesday in November by Act of Congress in 1941. Most Americans believe that the holiday dates back to the day of thanks ordered by Governor Bradford of Plymouth Colony in New England in 1621, but scholars say that the day of thanks is celebrated from ancient times.
Christmas
The most widely celebrated holiday of the Christian year, Christmas is observed as the anniversary of the birth of Jesus. Christmas customs are centuries old. Use of such plant as a holly comes from the ancient belief that such plants blossomed at Christmas. Comparatively recent is the Christmas tree, first set up in Germany in the 17th century and the use of candles on trees developed from the belief that candles appeared by miracle on the trees at Christmas.
