Overview

月日の配当パターンの種類が限定されている暦の抽象基底クラス

Calendar which has some fixed arrangement rules for under year

新年の日付が専用メソッドで与えられ、月日の配当が1年の日数等
で決まる暦。いわゆる Rule-Based な暦はほとんど該当します。

def _coordinates_to_number(y, m, d)
  sdn  = _sdn([+y])
  rule = _rule(_key([+y]))
  sdn += d + rule['Offset'][m]
  return sdn if d >= 0
  return sdn + rule['Length'][m % rule['Length'].length]
end

#_length(date) ⇒ Integer #_length(date) ⇒ Integer
