moment-jalali

moment-jalaali

A Jalaali (Jalali, Persian, Khorshidi, Shamsi) calendar system plugin for moment.js.

About

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.

Where to use it

Like momentjs, moment-jalaali works in browser and in Node.js.

Node.js

npm install moment-jalaali

var moment = require('moment-jalaali')
moment().format('jYYYY/jM/jD')

Browser

It is recommended to use component. Otherwise, you may use the build/moment-jalaali.js file.

<script src="moment.js"></script>
<script src="moment-jalaali.js"></script>
<script>
  moment().format('jYYYY/jM/jD')
</script>

API

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:

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('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:

moment.loadPersian()
