  • Includes full support for the Umm Al-Qura calendar.

• Custom Calendar Adjustments:

  • Supports saving and restoring calendar adjustments, allowing customization to reflect specific events like Ramadan and Eid declarations.

• Hijri and Gregorian Integration:

  • Combines both calendars seamlessly in a single programming operation.
  • Uses date-style format characters prefixed with _ for Hijri date formatting.

• Language Support:

  • Includes 20 global languages for Hijri month names.
  • Displays Gregorian dates in Arabic when the language is set to Arabic.

• Integration with PHP DateTime:

  • Fully compatible with PHP's DateTime class, with additional methods for Hijri-specific functionalities.
  • Automatically handles timezone differences.

Installation

You can install the package via Composer:

composer require kindy/hijridate

Namespace and Class Structure

The package follows a modular approach with the following structure:

• Namespace: Kindy\HijriDate
• Classes:
  • HijriDateTime: Handles Hijri date and time functionalities.
  • Calendar: Provides core conversion and calculation utilities.
  • CalendarAdjustment: Enables custom calendar adjustments.

Usage

Basic Example: Display Current Hijri Date

HijriDateTime Class

Constructor

public HijriDateTime::__construct(
    string $time = "now",
    DateTimeZone $timezone = null,
    string $langcode = null,
    Kindy\HijriDate\Calendar $calendar = null
)

• time : String in a format accepted by strtotime() default is 'now'
• $timezone : Time zone of the time default is ini timezone
• langcode: Default language (ar for Arabic, others default to English).
• calendar: Calendar object which used for calendar converting, if not set the class will create Calendar object with default settings.

Format Hijri Dates

public function format(string $format): string

Format Hijri Dates

public function format(string $format): string

Hijri Dates Static Method

HijriDateTime::Date('_Y-_m-_d','2024-12-3');

Hijri Dates objet by new instance

use Kindy\HijriDate\HijriDateTime;

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)

Convert Specific Gregorian Date to Hijri

echo (new HijriDateTime("2015-5-22"))->format('D _j _M _Yهـ (j-m-Yم)');
// 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:

Adjusted Gregorian Date Formatting in Arabic Language

When selecting the Arabic language, some Gregorian date formatting characters are adjusted as follows:

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);
}
