antnavdev/recurrence
====================

[](#antnavdevrecurrence)

Evaluate whether a recurring rule string is due on a given date. Pure PHP 8.2+, no framework dependencies.

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

[](#installation)

```
composer require antnavdev/recurrence
```

Usage
-----

[](#usage)

```
use AntNavDev\Recurrence\Recurrence;
use Carbon\Carbon;

$recurrence = new Recurrence('weekly:mon,wed,fri');
$recurrence->isDueOn(Carbon::parse('2026-04-13')); // Monday → true
$recurrence->isDueOn(Carbon::parse('2026-04-14')); // Tuesday → false
```

For rules that require an anchor date (`biweekly` and `interval`), pass it as the second constructor argument:

```
$recurrence = new Recurrence('biweekly:mon', anchorDate: Carbon::parse('2025-01-06'));
$recurrence->isDueOn(Carbon::parse('2025-01-06')); // week 0 → true
$recurrence->isDueOn(Carbon::parse('2025-01-13')); // week 1 → false
$recurrence->isDueOn(Carbon::parse('2025-01-20')); // week 2 → true

$recurrence = new Recurrence('interval:7', anchorDate: Carbon::parse('2025-01-01'));
$recurrence->isDueOn(Carbon::parse('2025-01-01')); // day 0 → true
$recurrence->isDueOn(Carbon::parse('2025-01-08')); // day 7 → true
$recurrence->isDueOn(Carbon::parse('2025-01-09')); // day 8 → false
```

Rule format
-----------

[](#rule-format)

Rule stringMeaning`null`Every day (same as `daily`)`daily`Every day`weekly:mon,wed,fri`Specific days of the week (lowercase 3-letter codes)`biweekly:mon`Every other week on that day, anchored to `anchorDate``monthly:15`The 15th of each month`monthly:last`The last day of each month`interval:N`Every N days from `anchorDate` (N < 1 is never due)Valid day-of-week codes: `mon`, `tue`, `wed`, `thu`, `fri`, `sat`, `sun`.

Exceptions
----------

[](#exceptions)

- `AntNavDev\Recurrence\InvalidRuleException` (extends `\InvalidArgumentException`) — thrown when the rule string cannot be parsed (e.g. `whenever:tuesday`, `monthly:foo`).
- `\LogicException` — thrown when `isDueOn()` is called with a `biweekly` or `interval` rule but no `anchorDate` was provided.

Running tests
-------------

[](#running-tests)

./vendor/bin/phpunit
