New York CNN —Leap Day might seem like fun and games — until you consider Wall Street. To account for that gap, Julius Caesar in 45 BC decreed that an extra day be added every four years, leading to the Julian calendar. Pope Gregory XIII in 1582 AD created the Gregorian calendar, coined the term “leap year” and established February 29 as the official leap day. He adds that a leap day can also help marginally raise corporate earnings, since companies get an extra day in a fiscal quarter to operate. History shows that stocks tend to perform worse when an additional day is added to the calendar.
