 DESCRIPTION
      easter displays date of Easter of the given year, in the format day
      month.

      The Gregorian reform is assumed to have ocurred in October 1582. That
      is, the days within 5 and 13 October 1582 didn't never exist.
      Nowadays, virtually all countries have adopted the Gregorian Calendar.

      Note this program calculates Easter as the Catholic Church does. This
      date is different from the Greek or Ortodox Church Easter.

      Ash Wednesday is 46 days before Easter. Palm Sunday is Sunday before
      Easter.  Lent is the period between Ash and Palm Sunday. Each Sunday
      in Lent is given a number (I, II, III, IV, V).

 BUGS
      Easter is calculated with present day (Gregorian) method, even for
      pre-1582 years. This is not really a bug, but a feature, because
      easter was designed for future prevision, and not for past analysis.
