The odd six hours, by accumulating for 4 years, make one day, so that every fourth year contains 366 days. This is called the Bissextile, or Leap year. When the Leap year occurs, the number of years up to that time is exactly divisible by 4. Thus 1800, 1804, 1808, 1812, 1816, 1820, 1824, 1828, and 1832 were all leap years. The year is also divided into 12 calendar months, which contain an unequal number of days. The additional day, when it occurs, is added to the month of February, so that this month has 29 days in the Leap year. Thirty days hath September, Excepting February, twenty-eight alone.
