1. The time of the apparent revolution of the sun trough the
   ecliptic; the period occupied by the earth in making its
   revolution around the sun, called the astronomical year;
   also, a period more or less nearly agreeing with this,
   adopted by various nations as a measure of time, and
   called the civil year; as, the common lunar year of 354
   days, still in use among the Mohammedans; the year of 360
   days, etc. In common usage, the year consists of 365 days,
   and every fourth year (called bissextile, or leap year) of
   366 days, a day being added to February on that year, on
   account of the excess above 365 days (see {Bissextile}).
