参考
支持1900-2100年份转换， 如果需要更长时间，请下载 generate.htm 中生成变量即可。

使用示例

  1. Solar solar = new Solar();
  2. solar.solarYear = 2018;
  3. solar.solarMonth = 9;
  4. solar.solarDay = 12;
  5. //阳历转阴历
  6. Lunar lunar = LunarSolarConverter.SolarToLunar(solar);
  7. //阴历转阳历
  8. solar = LunarSolarConverter.LunarToSolar(lunar);
  9. //年份转天干地支
  10. String ganZhi = LunarSolarConverter.lunarYearToGanZhi(lunar.lunarYear);
  11. System.out.println(lunar);
  12. System.out.println(solar);
  13. System.out.println(ganZhi);
  14. 结果：
  15. 阴历：2018年8月初3
  16. 阳历：2018年9月12日
  17. 戊戌年
