Installation

You can install the package via composer:

composer require asorasoft/chhankitek

Usage

// In your Laravel controller, use this trait
use HasChhankitek;

// Convert a date to lunar format
$toLunarDate = $this->chhankiteck(Carbon\CarbonImmutable::now()->setTimezone('Asia/Phnom_Penh'));
$toLunarDate->toString(); // ថ្ងៃច័ន្ទ ៤ រោច ខែបឋមាសាឍ ឆ្នាំឆ្លូវ ត្រីស័ក ពុទ្ធសករាជ ២៥៦៥

Available Methods

// In your Laravel controller, use this trait
use HasChhankitek;

$toLunarDate = $this->chhankiteck(Carbon\CarbonImmutable::now()->setTimezone('Asia/Phnom_Penh'));

// Get specific lunar date components
$toLunarDate->getDayOfWeek(); // អាទិត្យ, ច័ន្ទ...
$toLunarDate->getLunarDay(); // ១កើត, ២កើត...
$toLunarDate->getLunarMonth(); // ចេត្រ...
$toLunarDate->getLunarZodiac(); // ជូត, ឆ្លូវ...
$toLunarDate->getLunarEra(); // ត្រីស័ក...
$toLunarDate->getLunarYear(); // ២៥៦៥, ២៥៦៦..

Alternatively, you can use the toLunarDate helper function:

toLunarDate(Carbon\CarbonImmutable::now()->setTimezone('Asia/Phnom_Penh')); // ថ្ងៃច័ន្ទ ៤ រោច ខែបឋមាសាឍ ឆ្នាំឆ្លូវ ត្រីស័ក ពុទ្ធសករាជ ២៥៦៥

Caching

The Chhankitek package implements caching to improve performance when converting dates to lunar format. When you convert a date using the package, the result is cached for one year (365 days) to minimize computational overhead for frequently accessed dates.

How caching works

• Each converted date is cached
• Cache duration: 365 days (60 * 60 * 24 * 365 seconds)
• The package leverages Laravel's cache system, so it will use whatever cache driver you've configured for your application
