## What it is
Recurr is a PHP library for parsing, building, and transforming recurrence rules (RRULE from RFC 5545) into DateTime objects. It is designed to power calendars with recurring events and is inspired by rrule.js.

## Use cases
- parse RRULE strings into recurring event dates in PHP
- generate DateTime objects from recurrence rules for a calendar
- build RRULE strings programmatically with a fluent API
- compute occurrences of monthly or weekly recurring events
- limit or constrain generated recurrence dates
- implement recurring events in a scheduling application

## When to choose
- you need RFC 5545 RRULE support in a PHP project
- you are building a calendar or scheduling feature with recurring events
- you want a small focused library rather than a full iCalendar suite

## When to avoid
- you need full iCalendar file parsing or generation, not just RRULEs
- you are not working in PHP
- you need recurrence handling in JavaScript (use rrule.js instead)

## Facets
- artifact type: library
- maturity: active
- function: date-time, parser
- domain: developer-tools, web-development
- platform: php
- tags: rrule, recurrence-rules, calendar-events, rfc5545, icalendar
