A Flutter package for using Jalali (Shamsi, Solar or Persian) date. You can convert Jalali and Georgian dates to each other. #

Converted from the popular Javascript library jalaali-js.

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

Usage #

Add it to your pubspec.yaml file:

    shamsi_date: ^0.3.0

Jalali class is used for Shamsi (Jalali or Persian) date and Gregorian class is used for Gregorian date. They can be instantiated by using their constructor:

Jalali(year, month, day)
Gregorian(year, month, day)

month and day default to 1

You can convert Jalali date to Gregorian by using toGregorian() method and convert Gregorian to Jalali date by using toJalali() method.

You can check Jalali date validity by isValid() method. And find month length by monthLength getter. And check if the year is a leap year by isLeapYear() method.

You can also convert DateTime object directly to Jalali or Gregorian date by using


Here is an example:

import 'package:shamsi_date/shamsi_date.dart';

main() {
  final g1 = Gregorian(2013, 1, 10);
  final j1 = g1.toJalali();
  print('$g1 in Gregorian is $j1 in Jalali');

  final j2 = Jalali(1391, 10, 21);
  final g2 = j1.toGregorian();
  print('$j2 in Jalali is $g2  in Gregorian');

  // check validity
  print('$j1 is valid? ${j1.isValid()}');

  // check leap year
  print('1390 is leap year? ${Jalali(1390).isLeapYear()}');

  // find month length
  print('1390/12 month length? ${Jalali(1390, 12).monthLength}');
  final now =;
  print('now is ${Gregorian.fromDate(now)} in Gregorian');
  print('now is ${Jalali.fromDate(now)} in Jalali');
