## What it is
Yasumi is a PHP library for calculating the dates and names of holidays and special celebrations for many countries and states. It is rule-driven rather than database-driven, provider-based per country, and includes translations and timezone awareness.

## Use cases
- calculate holidays for a country and year in PHP
- check whether a given date is a public holiday
- get localized holiday names in multiple languages
- filter holidays by type such as official, bank, or observed
- add business-day logic that skips national holidays
- extend holiday calculations to a new country or region

## When to choose
- you need holiday data in a PHP 8.2+ project without relying on paid or limited external APIs
- you want a framework-agnostic, lightweight, pure-PHP solution
- you need multi-language holiday names and timezone awareness
- you want to add custom country or regional holiday providers

## When to avoid
- your project runs on PHP below 8.2
- you need real-time holiday data updates from an external service rather than rule-based calculation
- you need holidays for a country not covered by an existing provider and cannot write one

## Facets
- artifact type: library
- maturity: active
- function: date-time, internationalization
- domain: developer-tools, web-development
- platform: php, cross-platform
- tags: holidays, calendar, composer, provider-based, timezone-aware, localization
