js實現公曆(陽曆)和農曆(陰曆)的換算
阿新 • • 發佈:2022-04-15
1. 引入轉換js檔案:
import calendarFormatter from '@/common/dateChange.js'
2. 公曆轉農曆:
let nongli = calendarFormatter.solar2lunar(2020,5,26); console.log(nongli); // 結果如下: // {Animal: "鼠",IDayCn: "初四",IMonthCn: "閏四月",Term: null, //24節氣的中文名 astro: "雙子座",cDay: 26,cMonth: 5,cYear: 2020,gzDay: "己巳",gzMonth: "辛巳",gzYear: "庚子",isLeap: true, // 是否是農曆的閏月 isTerm: false, //是否是24節氣 isToday: false, //是否是今天 lDay: 4, lMonth: 4, lYear: 2020, nWeek: 2,ncWeek: "星期二"}
3. 農曆轉公曆:
let gongli = calendarFormatter.lunar2solar(2021, 9, 3); console.log(gongli) // 結果如下: // { Animal: "牛", IDayCn: "初三", IMonthCn: "九月",Term: "寒露",astro: "天秤座",cDay: 8,cMonth: 10,cYear: 2021, gzDay: "己丑",gzMonth: "戊戌",gzYear: "辛丑",isLeap: false,isTerm: true,isToday: false lDay: 3,lMonth: 9,lYear: 2021,nWeek: 5,ncWeek: "星期五" }
