A nativity scene is a depiction of the birth of Jesus as described in the gospels of Matthew and Luke. While the term "nativity scene" typically includes two dimensional depictions in film, painting, printmaking, and other media, the term popularly refers to static, three dimensional, commercial or folk art dioramas, or pantomimes called "living nativity scenes" in which real humans and animals participate. Nativity scenes exhibit (at the minimum) figures representing the infant Jesus, his mother Mary, and Mary's husband, Joseph.
The Twelve Days of Christmas, and the associated evenings of those twelve days (Twelve-tide), are the festive days beginning on Christmas Day (December 25) through to the evening of the Twelfth Day of Christmas, (January 5). Thus, the first night of Christmas is December 25–26 and Twelfth Night is January 5-6. This period is also known as Christmastide. The day after Twelfth Night is Epiphany on January 6.
Christmastide (also Christmas or the Christmas season) is one of the seasons of the liturgical year of most Christian churches. It tends to be defined (with slight variations) as the period from Christmas Day to the evening of 5 January, the day before Epiphany.
This period is also commonly known as the Twelve Days of Christmas, as referred to in the Christmas carol of the same name, or Yuletide, as in "Deck the Halls".
