getZuoYouIndex function

Map<String, int> getZuoYouIndex(
  1. int lunarMonth
)

获取左辅右弼的索引（按生月）

  • 辰上顺正寻左辅
  • 戌上逆正右弼当

解释：

  • 从辰顺数农历月份数是左辅的索引
  • 从戌逆数农历月份数是右弼的索引

@param lunarMonth 农历月份 @returns 左辅、右弼索引

  );
  final youIndex = fixIndex(
    fixEarthlyBranchIndex(EarthlyBranchName.xuEarthly) - (lunarMonth - 1),
  );
  return {"zuoIndex": zuoIndex, "youIndex": youIndex};
