## What it is
ice_cube is a Ruby library for defining and querying recurring event schedules using an iCalendar-inspired rule syntax. It lets you build recurrence rules and quickly check occurrences, such as whether a schedule falls on a given date or when its next occurrence is.

## Use cases
- create recurring event schedules in ruby
- check if an event occurs on a specific date
- list all occurrences of a repeating schedule
- find the next occurrence of a recurring event
- model iCalendar-style recurrence rules in ruby
- exclude specific dates from a recurring schedule

## When to choose
- you need flexible recurrence rules (daily, weekly, yearly, complex patterns) in a Ruby app
- you want fast queries like occurs_on?, next_occurrence, or occurrences between dates
- you're building calendar or scheduling features in Rails or another Ruby project

## When to avoid
- you need a full calendar UI or event storage solution rather than schedule computation
- you're not working in Ruby
- you need timezone-heavy or collaborative calendar sync features out of the box

## Facets
- artifact type: library
- maturity: stable
- function: scheduling, date-time, developer-tools
- domain: developer-tools, web-development
- platform: ruby
- tags: recurrence-rules, icalendar, schedules, recurring-events
