1 January

1 January was New Year's Day and the first day of the year on Earth. The year began with this day because, in 46 BC, Julius Caesar decided he'd start it on the shortest of all days — but when the priests complained, he made a compromise and used the first new moon after the shortest day of the year. This ended up being 1 January. (PROSE: The Doctor's Cross Word)
