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:

const m = moment('1367/11/4', 'jYYYY/jM/jD');
m.format('jYYYY/jM/jD [is] YYYY/M/D'); //1367/11/4 is 1989/1/24
m.jYear(); //1367
m.jMonth(); //10
m.jDate(); //4
m.jDayOfYear(); //310
m.jWeek(); //45
m.jWeekYear(); //1367
moment.jIsLeapYear(m.jYear()); //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

moment('1981 5 17', 'YYYY jM D').format('YYYY/MM/DD'); // 1981/07/17

To add Persian language, use loadPersian method:

moment.loadPersian()

A highly configurable date picker built for Angular 2 applications using jalali-moment is fingerpich/jalali-angular-datepicker created by @Fingerpich. In this I needed a plugin on moment.js to have Jalali date so at first I had been using moment-jalaali but I can't so I forked it and add some new feature to it.
