插件_日期_lunar-calendar公历农历转换

现在存在某需求，需要将公历、农历日期进行相互转换，在此借助lunar-calendar插件完成。

下载

• [1] 通过npm安装

  npm install lunar-calendar
  

• [2]通过文件方式引入

  <script type="text/javascript" src="lib/LunarCalendar.min.js"></script>
  

  此处我下载了LunarCalendar.min.js文件引入

使用

引入js文件之后，在window全局对象上添加了LunarCalendar对象，公农历转化的方法就是该对象的属性，可以全局作用域直接调用。

将公历转换为农历

语法

/* @param {Number} year 公历年 范围[1891-2100]@param {Number} month 公历月 范围[1-12]@param {Number} day 公历日 范围[1-31]
*/
LunarCalendar.solarToLunar(year,month,day)

返回值

举例说明

const obj = window.LunarCalendar.solarToLunar(2023, 10,1)
console.log(`今天的农历日期是${obj.lunarYear}年${obj.lunarMonthName}${obj.lunarDayName}日` ) // 今天的农历日期是2023年八月十七日
console.log(`今天是${obj.solarFestival}`) // 今天是国庆节 世界音乐日 国际老人节

将农历转换为公历

语法

/*@param {Number} year 农历年 范围[1891-2100]@param {Number} month 农历月 范围[1-13]（有闰月情况，比如当前闰9月，10表示闰9月，11表示10月）@param {Number} day 农历日 范围[1-30]
*/
LunarCalendar.lunarToSolar(year,month,day)

返回值

问题-month参数值

因为农历存在闰月的情况，因此month在传旨时的取值范围是1-13。

在进行转换时需要先知道今年哪月是闰月！month的参数值是否要+1？

举例说明

window.LunarCalendar.lunarToSolar(2023, 8,17)

如上 农历8月17日转化为公历为10月1日，但是结果为9月1日！

原因是在2023年润2月！

正确流程

• [1] 先获取今年润几月
• [2] 确定month传值
• 示例

  function lunarToSolar(year, month, day) {const { lunarLeapMonth } = LunarCalendar.calendar(year,month).monthData[0] // 润几月return window.LunarCalendar.lunarToSolar(year, month > lunarLeapMonth ? month+1 : month  ,day)
  }
  const date = lunarToSolar(2023, 8, 17)
