    A leap year is a year with 366 days instead of 365. One extra day is added to February every four years to account for the fact that a year doesn't contain 365 days but 365.25 days. Therefore, any year that is divisible by 4 is a leap year, such as 2016, 2020, 2024, and 2028.
    Leap years occur every four years, unless it falls on a century year that cannot be divided by four. The next leap year is in 2028. Leap Day that year will be observed on Tuesday, Feb. 29. After that, the next leap year is 2032, when Leap Day falls on Sunday, Feb. 29.
    The leap year was introduced by Julius Caesar in 45 B.C. during the adoption of the Julian Calendar. Caesar employed a mathematician called Sosigenes of Alexandria to address the problem of the drifting calendar, which the Roman Empire had also noticed.
    The Gregorian calendar has only 365 days in a year, but it takes Earth approximately 365.242189 days, or approximately 1 extra day every 4 years, to circle once around the Sun. Leap days keep our calendar in alignment with Earth's revolutions around the Sun.
