25 Leap Days That Made the News

Every four years we add an extra day to February called leap day to keep our calendar aligned with the Earth’s revolutions around the sun. It takes 365 days, 5 hours, 48 minutes, and 45 seconds for our planet to travel around the sun.

If we didn’t add the extra day in February every four years, we would lose nearly six hours every year. That can add up — our calendar would be off by about 24 days after just 100 years if we didn’t make the adjustment.

Even though a leap day occurs every four years, significant news events have happened on Feb. 29 throughout history, among them one of the most notorious in colonial America. On Feb . 29, 1692, the first three women were accused of witchcraft in Salem, Massachusetts — a city founded before the American Revolution (here are 100 towns founded before the American Revolution). This led to the infamous Salem Witch Trials.

247 Wall St. compiled a list of the most notable events that have occurred on leap days throughout history.
