Jalaali (Jalali, Persian, Khorshidi, Shamsi) calendar system plugin for moment.js.
npm install moment-jalaaliA Jalaali (Jalali, Persian, Khorshidi, Shamsi) calendar system plugin for moment.js.
Jalali calendar is a solar calendar that was used in Persia, variants of which today are still in use in Iran as well as Afghanistan. Read more on Wikipedia or see Calendar Converter.
This plugin adds Jalaali calendar support to momentjs library.
Calendar conversion is based on the algorithm provided by Kazimierz M. Borkowski and has a very good performance.
If you just need to display date and time in Persian calendar, you may use Intl which is ECMAScript Internationalization API with a very good browser support. For example:
``js
const d = new Date(2022,2,21)
// Simple format
console.log(new Intl.DateTimeFormat('fa-IR').format(d));
// => ۱۴۰۱/۱/۱
// Full long format
console.log(new Intl.DateTimeFormat('fa-IR', {dateStyle: 'full', timeStyle: 'long'}).format(d));
// => ۱۴۰۱ فروردین ۱, دوشنبه، ساعت ۰:۰۰:۰۰ (+۳:۳۰ گرینویچ)
// Latin numbers
console.log(new Intl.DateTimeFormat('fa-IR-u-nu-latn', {dateStyle: 'full', timeStyle: 'long'}).format(d));
// => 1401 فروردین 1, دوشنبه، ساعت 0:00:00 (+3:30 گرینویچ)
// English US locale with Persian calendar
console.log(new Intl.DateTimeFormat('en-US-u-ca-persian', {dateStyle: 'full', timeStyle: 'long'}).format(d));
// => Monday, Farvardin 1, 1401 AP at 12:00:00 AM GMT+3:30
// Just year
console.log(new Intl.DateTimeFormat('en-US-u-ca-persian', {year: 'numeric'}).format(d));
// => 1401 AP
// Just month
console.log(new Intl.DateTimeFormat('en-US-u-ca-persian', {month: 'short'}).format(d));
// Farvardin
// Just day
console.log(new Intl.DateTimeFormat('en-US-u-ca-persian', {day: 'numeric'}).format(d));
// => 1
`
Like momentjs, moment-jalaali works in browser and in Node.js.
`shell`
npm install moment-jalaali
`js`
var moment = require('moment-jalaali')
moment().format('jYYYY/jM/jD')
You may use the node_modules/build/moment-jalaali.js file.
`html`
If you need type definitions for typescript, you need to install them separately.
`shell`
npm install @types/moment-jalaali
This plugin tries to mimic momentjs api. Basically, when you want to format or parse a string, just add a j to the format token like 'jYYYY' or 'jM'. For example:
`js
m = moment('1360/5/26', 'jYYYY/jM/jD') // Parse a Jalaali date
m.format('jYYYY/jM/jD [is] YYYY/M/D') // 1360/5/26 is 1981/8/17
m.jYear() // 1360
m.jMonth() // 4
m.jDate() // 26
m.jDayOfYear() // 150
m.jWeek() // 22
m.jWeekYear() // 1360
m.add(1, 'jYear')
m.add(2, 'jMonth')
m.add(3, 'day')
m.format('jYYYY/jM/jD') // 1361/7/29
m.jMonth(11)
m.startOf('jMonth')
m.format('jYYYY/jM/jD') // 1361/12/1
m.jYear(1392)
m.startOf('jYear')
m.format('jYYYY/jM/jD') // 1392/1/1
m.subtract(1, 'jYear')
m.subtract(1, 'jMonth')
m.format('jYYYY/jM/jD') // 1390/12/1
moment('1391/12/30', 'jYYYY/jMM/jDD').isValid() // true (leap year)
moment('1392/12/30', 'jYYYY/jMM/jDD').isValid() // false (common year)
moment.jIsLeapYear(1391) // true
moment.jIsLeapYear(1392) // false
moment.jDaysInMonth(1395, 11) // 30
moment.jDaysInMonth(1394, 11) // 29
moment('1392/6/3 16:40', 'jYYYY/jM/jD HH:mm').format('YYYY-M-D HH:mm:ss') // 2013-8-25 16:40:00
moment('2013-8-25 16:40:00', 'YYYY-M-D HH:mm:ss').endOf('jMonth').format('jYYYY/jM/jD HH:mm:ss') // 1392/6/31 23:59:59
// Complex parse:
moment('1981 5 17', 'YYYY jM D').format('YYYY/MM/DD') // 1981/07/17
`
To add Persian language, use loadPersian method:
`js`
moment.loadPersian([options])
| Param | Type | Default | Description | Example |
| ---------------- | ------- | ------- | ---------------------------------------- | -------------------------------------------- |
| usePersianDigits | Boolean | false | Use persian digits (Use at your own risk) | moment.loadPersian({usePersianDigits: true}) |persian
| dialect * | String | | Available values = persian, persian-modern | moment.loadPersian({dialect: 'persian-modern'}) |
*use dialect option to change usePersian dialect, available options are:
* persian: default dialect(امرداد، آدینه، ...)
* persian-modern: modern dialect(مرداد، جمعه، ...)
#### in case getting error 'humanize' of undefined
you should also require locale fa
`js`
require('moment/locale/fa')
To use fromNow() in React Native projects:
`js`
import moment from "moment-jalaali";
import fa from "moment/src/locale/fa";
moment.locale("fa", fa);
moment.loadPersian();
