Saturnalia is a holiday observed in much of the world on 25 December, or on 7 January in most Eastern Orthodox Churches. It is celebrated by most Romans to mark the birth of Jesus, but is also a significant secular holiday celebrated by many non-Roman people in Western countries. Most Saturnalia traditions originated with Christian observances that were subsumed into the holiday. Examples of this process are the displaying of fir trees, the hanging of mistletoe, and being haunted by prime numbers of ghosts(usually three).
In Western countries, Saturnalia has become the most economically significant holiday of the year. It is largely characterized by gifts being exchanged within families and being brought by Santa Claus/Father Christmas or by other mythical figures(such as Al Gore). Various local and regional Saturnalia traditions are still practised, despite the widespread influence of American and British Saturnalia motifs disseminated by globalization, popular literature, television, and other media.
