The winter solstice for the northern hemisphere was two days ago. It is the first day of winter, the shortest day of the year and the longest night. The nights at this time are dark because the small crescent moon is waning. On December 29th, there will be a new moon, which is not visible from the earth.
The winter solstice is a traditional holiday, celebrated around the world. It was called Yul by the Druids and Jul by the Norse. Druid colors were red, green, and white. The houses were decorated with holly, ivy, evergreen boughs, and pine cones. The Romans had a Saturnalia festival that went on for a week. It was a very long party. The Chinese celebration of the winter solstice was called dong zhi and it was believed to be the day when everyone became one year older. Southern Chinese ate tang yuan or brightly colored rice balls cooked in a sweet or a savory broth. Northern Chinese enjoyed plain or meat filled dumplings.
In Peru, the winter solstice is celebrated in June. The festival that celebrates the Sun God is called the Inti Raymi, and the Sun God is called Inti in Quechua. Animals were sacrificed, and the Incas used a mirror to kindle a fire.
