What is Solstice?
Winter Solstice, the shortest day of the year in the Northern hemisphere, falls on December 21st and marks the official start of the winter season. On the same day, people living in the Southern hemisphere have their Summer Solstice and mark their longest day of the year! These days flip flop in June, when we have our longest day of the year and our first day of summer in the Northern hemisphere and the Southern countries move into winter.
