Introduction

jalali(Persian) calendar is a solar calendar system. It gains approximately 1 day on the Julian calendar every 128 years. Read more on Wikipedia.

Calendar conversion is based on the algorithm provided by Kazimierz M. Borkowski and has a very good performance.

This plugin adds Jalali (Persian, Khorshidi, Shamsi) calendar system to moment.js library.

API

This plugin tries to mimic moment.js 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:

now = moment(); //get the current date and time,

Parse

Create a instance of moment from a Jalali (Persian) or Miladi date and time as string.more

m = moment('1367/11/4', 'jYYYY/jM/jD');// parse a jalali (persian) date
m = moment('1989/1/24', 'YYYY/M/D');// parse a gregorian (miladi) date

Display jalali or miladi date

Display moment instance as a string.more

m.format('jYYYY/jM/jD');// 1367/11/4 
m.format('jMM'); // 11 display jalali month
m.format('M'); // 1 display miladi month
m.format('MM'); // 01 display month by two digit
m.format('MMMM'); // January
m.format('jMMMM'); // Bahman
m.format('jDD'); // 04 display day by two digit
m.format('jYYYY/jM/jD [is] YYYY/M/D'); // 1367/11/4 is 1989/1/24
m.jDayOfYear(); // 310
m.jWeek(); // 45
m.jWeekYear(); // 1367

Manipulate

There are a number of methods to modify date and time.more

m.jYear(1368); // set jalali year
//  If the range is exceeded, it will bubble up to the year.
m.jMonth(3); // month will be 4 and m.format("M")=='4' , jMonth Accepts numbers from 0 to 11.
m.jDate(10); // set a date
m.format("jYYYY/jMM/jD"); // 1368/4/10
m.subtract(1, "jyear"); // add a Jalali Year
m.format("jYYYY/jMM/jD"); // 1367/4/10
m.add(2, "jmonth"); // add Jalali Month
m.format("jYYYY/jMM/jD"); // 1367/6/10
m.endOf('jMonth').format("jYYYY/jMM/jD"); // 1367/6/31
m.startOf('jYear').format("jYYYY/jMM/jD"); // 1367/1/1

Validate

Check a date and time.more

m = moment('1367/11/4', 'jYYYY/jM/jD');
m.jIsLeapYear(); // false
m.isLeapYear(); // false
m.isSame('1989-01-01', 'year'); // true
m.isSame(moment('1367-01-01','jYYYY-MM-DD'), 'jyear'); // true
m.isBefore(moment('1367-01-01','jYYYY-MM-DD'), 'jyear'); // false
m.isAfter(moment('1367-01-01','jYYYY-MM-DD'), 'jyear'); // false

Convert persian(Jalali , Shamsi, khorshidi) to gregorian (miladi) calendar system

moment('1392/6/3 16:40', 'jYYYY/jM/jD HH:mm')
    .format('YYYY-M-D HH:mm:ss'); // 2013-8-25 16:40:00

Convert gregorian (miladi) to jalali (Shamsi, persian)

moment('2013-8-25 16:40:00', 'YYYY-M-D HH:mm:ss')
    .format('jYYYY/jM/jD HH:mm:ss'); // 1392/6/31 23:59:59

Load Persian

To add Persian language, use loadPersian method:

moment().format('jYYYY/jMMMM/jD'); // 1367/Bahman/4
moment.loadPersian();
moment().format('jYYYY/jMMMM/jD'); // 1367/بهمن/4
moment.loadPersian(true); //use persian digits
moment().format('jYYYY/jMMMM/jD'); // ۱۳۶۷/بهمن/۴
moment.unloadPersian();
moment().format('jYYYY/jMMMM/jD'); // 1367/Bahman/4

Use jalali calendar system primarily

This plugin adds Jalali calendar system to moment.js which is using gregorian calendar system so we could use both calendar system concurrently but you could use Jalali calendar as default system like the following code:

moment().format('YYYY/MMMM/D'); // 1989/January/24
moment.useJalaliSystemPrimarily();
 
moment().format('YYYY/MMMM/D'); // 1367/Bahman/4
moment().subtract(1,'year').format('YYYY/MMMM/D'); // 1366/bahman/4
moment().subtract(1,'month').format('YYYY/MMMM/D'); // 1367/dey/4
 
moment.useJalaliSystemSecondary();
moment().format('YYYY/MMMM/D'); // 1989/January/24

For example: to make a datepicker work with jalali calendar system you could use this feature.
