WizCalendar（巫师万年历）

巫师万年历是一款采用天文算法实现的高精度万年历模块。提供了简便易用的API，清晰易读的面向对像代码设计，可以很容易地开发一个万年历和进行历法研究。 主要参考了寿星万年历。

如何使用：

同时支持javascript和typescript两种语言。

1. 通过npm安装

   > npm i wiz-calendar

2. 导入模块

   javascript导入方式：

   const {WizCalendar, SolarDate, LunarDate, JulianDate, MoonPhase,MoonPhaseName} = require("wiz-calendar");

   typescript导入方式：

   import {WizCalendar, SolarDate, LunarDate, JulianDate, MoonPhase,MoonPhaseName} from 'wiz-calendar';

基本用法：

1. 阳历转阴历

   //let solar = new SolarDate(1977, 5, 18);
   let solar = WizCalendar.solarDate(1977, 5, 18);
   let lunar: LunarDate = solar.getLunarDate();
   lunar.format('date'); //1977-04-01+0

2. 阴历转阳历

   //let lunar = new LunarDate(1977,4,1);
   let lunar = WizCalendar.lunarDate(1977,4,1);
   let solar: SolarDate = lunar.getSolarDate(); 
   solar.format('date'); //1977-05-18

3. 阳历转儒略日

   //let solar = new SolarDate(1977, 5, 18);
   let solar = WizCalendar.solarDate(1977, 5, 18);
   let julian: JulianDate = solar.getJulianDate(); 
   julian.getJD(); //2443282

4. 阴历转儒略日

   //let lunar = new LunarDate(1977, 4, 1, 12);
   let lunar = WizCalendar.lunarDate(1977,4,1);
   let julian: JulianDate = lunar.getJulianDate(); 
   julian.getJD(); //2443282

5. 儒略日转阳历

   let mjd = 5225.942824074067; //J2000算起的儒略日
   //let julian = new JulianDate(mjd);
   let julian = WizCalendar.julianDate(mjd);
   let solar: SolarDate = julian.getSolarDate();
   solar.format('datetime'); //2014-04-23 10:37:40

6. 儒略日转阴历

   let mjd = -8263; //J2000算起的儒略日
   //let julian = new JulianDate(mjd);
   let julian = WizCalendar.julianDate(mjd);
   let lunar: LunarDate = julian.getLunarDate();
   lunar.format('datetime'); //1977-04-01+0 12:00:00

7. 获取二十四节气

   //let lunar = new LunarDate(1977,4,1);
   let lunar = WizCalendar.lunarDate(1977,4,1);
   let julian: JulianDate = lunar.getSolarTerm(SolarTermName.WinterSolstice);

8. 阴历干支纪历

   //let lunar = new LunarDate(1977,4,1);
   let lunar = WizCalendar.lunarDate(1977,4,1);
   lunar.getYearStem() + lunar.getYearBranch(); //丁巳
   lunar.getMonthStem() + lunar.getMonthBranch(); //乙巳
   lunar.getDayStem() + lunar.getDayBranch(); //乙亥

9. 获取命理八字

   //2014-4-23 10:37:40   
   //甲午年 戊辰月 甲子日 己巳时 真太阳 10:24:48
   //let eight = new EightChar(5225.942824074067);
   let eight = WizCalendar.eightChar(5225.942824074067);
   eight.getYear(); //甲午
   eight.getMonth(); //戊辰
   eight.getDay(); //甲子
   eight.getHour(); //己巳
   

10. 获取月相(朔望)

    let lunar = WizCalendar.lunarDate(1977,4,1);
    let phase = lunar.getMoonPhase(MoonPhaseName.NewMoon);
    phase.getJulianDate().getMJDN(); //-8263

11. 获取24节气

    let lunar = WizCalendar.lunarDate(1977,4,1);
    let term = lunar.getSolarTerm(SolarTermName.WinterSolstice);
    term.getJulianDate().getMJDN(); //-8045
