BISSEXTILE
n.[L. bissextilis, leap year, from bissextus, [bis and sextus ] the sixth of the calends of March, or twenty-fourth day of February, which was reckoned twice every fourth year, by the interrelation of a day. ] Leap year; every fourth year, in which a day is added to the month of February, on account of the excess of 6 hours, which the civil year contains, above 365 days. This excess is 11 minutes 3 seconds too much; that is, it exceeds the real year, or annual revolution of the earth. Hence at the end of every century, divisible by 4, it is necessary to retain the bissextile day, and to suppress it at the end of those centuries which are not divisible by 4.

BISSEXTILE
Bis *sex "tile, n. Etym: [L. bissextilis annus, fr. bissextus (bis +sextus sixth, fr. sex six ) the sixth of the calends of March, or twenty-fourth day of February, which was reckoned twice every fourth year, by the intercalation of a day. ]
Defn: Leap year; every fourth year, in which a day is added to the month of February on account of the excess of the tropical year (365 d. 5 h. 48 m. 46 s.) above 365 days. But one day added every four years is equivalent to six hours each year, which is 11 m. 14 s. more than the excess of the real year. Hence, it is necessary to suppress the bissextile day at the end of every century which is not divisible by 4 , while it is retained at the end of those which are divisible by 4 .
