shamsi_date's Issues

The problem of 2124/03/20

Problem:
The Gregorian date 2124/03/20 must be 1503/01/01 in the Jalali calendar but this lib returns 1502/12/30.

Checks:
The Gregorian date 2025/03/20 must be 1403/12/30 in the Jalali calendar which currently is correct but must be rechecked after fixing the reported problem.

@roozbehp typed in the leap year data from the Iranian calendar authority and put it at: https://github.com/roozbehp/persiancalendar/blob/main/kabise.txt

It would be great if automatic tests could be added based on that data to this project.

is it possible get holidays

Hi, i wanna get holidays in week. is it possible calculate holidays?
thank you

Make dates comparable

It would be nice to be able to compare Jalali dates without converting them to DateTime objects or comparing their fields.

bug in addMonths method

shamsi_date/lib/src/jalali/jalali_date.dart

Line 258 in 218ef76

return Jalali(year + deltaYear, mod + 1, day);

این متد روز رو تغییر نمیده ، و مثلا اگر 31 شهریور باشیم میره به 31 مهر و خطا میخوره . ممنون میشم بررسی کنید

Why screenshots of calendar is not included in this package?

when i add shamsi_date package to dependencies and run pub get i get this error Package not available (authorization failed)

Suppose I have 2 Jalali instances, how do I diff them in months? I suppose converting them back to DateTime and using difference method won't work, because there's no correlation between Jalali and Gregorian month diffs.

Convert To Jalali directly from '2021-02-10T17:42:01'

Hi
To get Gregorian from DateTime I have to use DateTime date = DateTime.parse(dateString); first and then use Jalali.fromDateTime(dateTime);

It will be easier to have a shortcut for that.

How to access time data?

I want to show time next to date, e.g.: 1399/06/15 23:55

How can I do it with this library?

I using MillisecondsEpoch.

Month checking Issue

There was an error in Jalali formatter file which was an if statement checking if received month is treater than ml or not(ml being month length). months are 31 or 30 but it just accepted lower than this number meaning greatest month length was 30 so I got an error and check you code and found it out. I committed my change so it would be great if you accepted it ASAP because Im using it inside my project. Thanks in advance :)

error when i add the package to dependencies

When I add shamsi_date package to dependencies and run pub get I get this error ---> Package not available (authorization failed)

Jalali day is out of valid range.

Hi, I am trying to get session by this command:
Jalali.now().copy(month: 12).formatter.mN

But I got This error :

 Jalali.now().copy(month: 12).formatter.mN
Unhandled exception:
DateException: Jalali day is out of valid range.
#0      new Jalali (package:shamsi_date/src/jalali/jalali_date.dart:129:9)
#1      Jalali.copy (package:shamsi_date/src/jalali/jalali_date.dart:222:14)
#2      MonthPickerModel.Eval ()

I expect that I get اسفند .

month range error

there is a problem on
(dateProvider as Jalali).withDay(30).addMonths(-1)
when month is 1 and day is 30 or 31.

Jalali day is out of valid range

Hi
I have the same problem here
The point is this is ONLY happening today at 1400/05/31 (8/2/2021) and was working fine the other days

code where this is happening

Jalali date;
var initDate = '1400/05/31';
var splitDate = initDate.split("/");
var date1 = Jalali(int.parse(splitDate[0]), int.parse(splitDate[1]), int.parse(splitDate[2]));
date = date1.addMonths(3);      -------------> The line that exception happens

the Exception:

Even by changing the date (e.g. 1400/05/31 -> 1400/05/20 Or even 1400/04/20), the Exception still occurs

The method distanceTo isn't defined for type Jalali

I have this jalali instance :

    jStartDate = jStartDate.withDay(1);
    jEndDate = jEndDate.withDay(1);

I want to find out how many days are between jStartDate and jEndDate ?
So in order to find out days I am using :
int distance = jStartDate.distanceTo(jEndDate);

But I got: 'The method distanceTo isn't defined for type 'Jalali`

addMonth() make invalid date in some cases

addMonth() method just go to the next month on same day but in some cases there are no such a date, like next month of 31/6 which is 31/7 or previous month of 31/1 which is 31/12

.toIso8601String() extension support

please add .toIso8601String() extension to the package

copy(), withDay(), ... not exist

hello
I want to use copy(...) method or withYear, withMonth and withDay methods on an existing object but these methods don't exist in Jalaali objects.

Jalali day is out of range

Hello and thanks for the great work... there is a problem with the package... there are months in the gregorian calendar that are 29 days and those months are 30 days or 31 in Shamsi calendar... in this kind of months, the calendar would not work because ml => month length would be less than days of months.
