• POS: Noun Phrase

CIDE DICTIONARY

leap year, n. 

 Bissextile; a year containing 366 days; every fourth year which leaps over a day more than a common year, giving to February twenty-nine days. See Bissextile.  [1913 Webster]
" Every year whose number is divisible by four without a remainder is a leap year, excepting the full centuries, which, to be leap years, must be divisible by 400 without a remainder. If not so divisible they are common years. 1900, therefore, is not a leap year, but 2000 is."  [1913 Webster]
