Happy Leap Day everyone. According to National Geographic, the Egyptians were among the first to implement this whole extra-day-every-four-years trend back during the good ole Ptolemaic dynasty (305 to 30 B.C.).
Cleopatra, the last Ptolemaic ruler, reportedly introduced the idea to Julius Ceasar, who then mandated that Rome honor a 445-day year to accommodate the lost time. The year of 46 BC was later named the Year of Confusion.
In honor of Cleo and Jules, here’s a pretty picture of the Nile river, care of cyanocorax.
