'Convert date and time to Jalali in Laravel

I want to change the time and date calendar to Jalali (Shamsi calendar used in Iran) in my system. How can I do this?

	"language_title" => "English",
	"dir" => "ltr", // ltr = left to right, rtl = right to left
	"language_code" => "en",
	"intl_locale" => "en_US",
	"dec_point" => ".",
	"thousands_sep" => ",",
	"dateformat_full" => "D, M j Y  g:i A", // http://php.net/manual/en/function.date.php
	"dateformat_date_long" => "D, M j Y", // http://php.net/manual/en/function.date.php
	"intl_dateformat_full" => "E, d MMM yy  h:m a", // http://userguide.icu-project.org/formatparse/datetime
	"intl_dateformat_date_long" => "E, d MMMM yyyy", // http://userguide.icu-project.org/formatparse/datetime

Solution 1:^[1]

You can use Jalali/Morilog.

To Convert Jalali Date To Georgian Carbon Date:

$jalaliDate = "1399/08/06";
$georgianCarbonDate=\Morilog\Jalali\Jalalian::fromFormat('Y/m/d', $jalaliDate)->toCarbon();

and to Convert Georgian Carbon Date to Jalali Date:

$jalaliDate=\Morilog\Jalali\Jalalian::fromCarbon($carbonDate)->format('Y/m/d'); // output is a jalali date string like 1399/08/06

Many years ago, I made a third party calendar helper to convert a Gregorian date to Jalali. I use it inside a Laravel service. The main methods are jNow and jdate

<?php

namespace Infrastructure\Services\Calendar;

class CalendarHelper
{

    public function jDisplay($timestamp)
    {
        list($hour, $minute, $second) = explode( ':', date( 'H:i:s', time() ) );
        $today = time() - ( $hour*3600+$minute*60+$second );
        if ( $timestamp > $today ) return '?????';
        elseif ( $timestamp > $today-86400 ) return '?????';
        else return $this->jdate( $timestamp, false, true );
    }

    public function yearList($end=1970)
    {
        $year = (int)date('Y', time());
        return $this->_yearList($year, $end);
    }

    private function _yearList($year, $end)
    {
        if ( $year < $end ) return array();

        $years[] = $year;
        while ( $year > $end ) {
            $year--;
            $years[] = $year;
        }
        return $years;
    }

    public function jYearList($end=1340)
    {
        $list = explode(' ', $this->jdate( date('Y-m-d-D H:i:s', time()), true, false ) );
        $year = (int)$list[3];
        return $this->_yearList($year, $end);
    }

    public function jNow()
    {
        $list = explode(' ', $this->jdate( date('Y-m-d-D H:i:s', time()), true, false ) );
        return array(
            'year' => $list[3],
            'month' => $list[2],
            'day' => $list[1],

            'time' => $list[4]
        );
    }

        list($g_y, $g_m, $g_d) = $this->jalali_to_gregorian($j_y,$j_m,$j_d);
        $hour = str_pad( $hour, 2, '0', STR_PAD_LEFT );
        $minute = str_pad( $minute, 2, '0', STR_PAD_LEFT );
        $time_str = $g_y.'-'.$g_m.'-'.$g_d.' '.$hour.':'.$minute.':00';
        $time = strtotime($time_str);
        $time -= 12600;
        return $time;
    }

Converting from the western (Gregorian) calendar to another calendar is going to be difficult. A quick Google search came up with one item:

persian_date - a PHP library for converting dates between Gregorian and Persian calendars.

Note that I have not tried to use this library, nor am I even sure it's going to do what you want.

Solution 4:^[4]

in config/app.php set timezone to 'Asia/Tehran' but it saves only time based on iran for converting Gregorian to Shamsi Date you can use Miladr Package

Solution 5:^[5]

In your config/app.php file, you've to change the following setting :

/*
|--------------------------------------------------------------------------
| Application Timezone
|--------------------------------------------------------------------------
|
| Here you may specify the default timezone for your application, which
| will be used by the PHP date and date-time functions. We have gone
| ahead and set this to a sensible default for you out of the box.
|
*/

'timezone' => 'IST',

Assuming that your timezone is IST :)

Solution 6:^[6]

$wrongFormat = 1360-1-1;
$correctFormat = 1360-01-01;

You can use like this:

$correctDate = date('Y-m-d',strtotime($wrongFormat));
$miladiDate = \Morilog\Jalali\CalendarUtils::createCarbonFromFormat('Y-m-d',$correctDate);

Solution 7:^[7]

you can use morilog/jalali package.

1- Run the Composer update command

    composer require morilog/jalali:3.*

2- Add name space

 use Morilog\Jalali\Jalalian;

3- Basic Usage

Convert Jalali to Carbon

 $jDate = "1400/07/05";
 $date = Jalalian::fromFormat('Y-m-d', $date)->toCarbon();

Convert Carbon to Jalali

 $date = '2020/09/27';
 $jDate = Jalalian::fromCarbon($date)->format('Y-m-d');
 // or
 $jDate = jdate($date)->format('Y-m-d');

also u can use Y-m-d H:i:s or H:i:s as format.
