Christmas time, holiday season, Yuletide, festivities, winter or summer holidays... Depending on where you are in the world, the period between late November and early January can be known by various names.
Throughout history, multiple celebrations have taken place during this time of the year. Layouts of late Neolithic archaeological sites indicate that the winter solstice in the Northern Hemisphere was a special moment for some cultures. In ancient Rome, the Saturnalia festival honored the god of time with celebrations that lasted multiple days in December.
Since the 19th and 20th centuries, as the economic impact involving the lead-up to Christmas Day grew in North America and Europe, the term "Christmas season" became known as a peak season for the retail sector and began to also encompass the days right before and after 25 December.
Today, this holiday season begins in late November and runs until early January, including Advent, Christmas, New Year's Day, Hannukah, Yule, Kwanzaa, and more celebrations. In some traditions, Candlemas is the official end of the festivities, taking place on 2 February.
