Immutable date-time operations, timezone conversion, strict parsing, ICU formatting, business calendars, and PSR-20 clocks for PHP applications.

Requirements
------------

[](#requirements)

- PHP 8.2 or newer
- `psr/clock` 1.0
- `ext-intl` with the required ICU locale data for localized and human-readable formatting

Installation
------------

[](#installation)

```
composer require codemonster-ru/datetime:^1.0
```

Quick start
-----------

[](#quick-start)

```
use Codemonster\DateTime\DateTime;
use Codemonster\DateTime\FrozenClock;

$clock = new FrozenClock(new \DateTimeImmutable('2026-07-31 05:30:00 UTC'));

$publishedAt = DateTime::now($clock, 'Asia/Novokuznetsk')
    ->addDays(2)
    ->subtractHours(3)
    ->toTimezone('UTC');

echo $publishedAt->toIso8601String();
```

All value operations are immutable. Calendar units such as days and months preserve local calendar semantics, while hours, minutes, and seconds represent elapsed time.
