echo (new HijriDateTime())->format('_j _M _Yهـ');
// Output: 8 شعبان 1436هـ

Hijri and Gregorian Dates Together

echo (new HijriDateTime())->format('D _j _M _Yهـ (j-m-Yم)');
// Output: الثلاثاء 8 شعبان 1436هـ (26-05-2015م)

// Output: الجمعة 4 شعبان 1436هـ (22-05-2015م)

Create Hijri Date Object from Hijri Date

use Kindy\HijriDate\HijriDateTime;

$hijirDate = HijriDateTime::createFromHijri(1436, 9, 1);
echo $hijirDate->format('D _j _M _Yهـ (j-m-Yم)');
// Output: الخميس 1 رمضان 1436هـ (18-06-2015م)

Formatting Time and Date in the Hijri Calendar

The function formats time and date using specific characters, with no differences in parameters but varying outputs depending on the characters used. Below is a table explaining the functionality of each character:

Character	Description	Example Output
_j	Day without leading zeros	1-30
_d	Day with leading zeros	01-30
S	Ordinal suffix (English only, new in version 2.3)	st-nd-th
_z	Day of the year (starting from zero)	0-354
_M, _F	Month name	محرم, صفر, ...
_m	Month number with leading zeros	01-12
_n	Month number without leading zeros	1-12
_t	Number of days in the month	29-30
_L	Leap year indicator (1 = Leap Year, 0 = Not Leap Year)	1 or 0
_Y	Full year number	1436
_y	Two-digit year	36

Adjusted Gregorian Date Formatting in Arabic Language

Extended Features

Additional Methods

The HijriDateTime class includes custom methods for Hijri-specific functionalities:

• HijriDateTime::createFromHijri(year, month, day): Creates a HijriDateTime object from a specific Hijri date.

• HijriDateTime::setDateHijri(year, month, day): Sets the Hijri date for an existing HijriDateTime object.

Calendar Class

The Calendar class provides low-level utilities such as:

• Conversion between Julian and Hijri calendars.
• Determining leap years.
• Validating Hijri dates.

Example: Days in Hijri Month

use Kindy\HijriDate\Calendar;

echo (new Calendar())->days_in_month(9, 1436);
// Output: 29

Using the Package with Legacy Code

If you want to use this library without changing existing DateTime-dependent code, alias HijriDateTime as DateTime:

use Kindy\HijriDate\HijriDateTime as DateTime;

Alternatively, create a custom hdate() function to replace PHP's date():

function hdate($format, $timestamp = null)
{
    if (!isset($timestamp)) {
        $timestamp = time();
    }
    $d = new HijriDateTime('@' . $timestamp);
    return $d->format($format);
}
