## What it is
Schedule-X is a modern JavaScript event calendar library for web apps, offering responsive views, internationalization, and an extensible plugin system. It provides official components for React, Vue, Angular, Svelte, and Preact, and positions itself as a modern alternative to FullCalendar and react-big-calendar.

## Use cases
- add an event calendar to a react app
- modern alternative to fullcalendar
- display and manage calendar events in vue
- build a responsive scheduling ui in angular or svelte
- support drag and drop event rescheduling
- render icalendar events in a web calendar
- internationalized calendar with multiple languages

## When to choose
- you need a modern, actively maintained event calendar for a JS framework app
- you want responsive calendar views with i18n and theming out of the box
- you want to extend calendar behavior via a plugin system or custom framework components

## When to avoid
- you need drag-and-drop, resize, or resource scheduling without paying for the premium plugins
- you need a non-JavaScript or server-rendered-only calendar
- you require fullcalendar-compatible APIs or its exact plugin ecosystem
