## What it is
A dependency-free Web Component that renders configurable 'Add to Calendar' buttons for websites and web apps. It generates links for Google, Apple, Yahoo, Microsoft 365/Outlook/Teams, and generic iCal calendars and works with any HTML page or JS framework.

## Use cases
- add an add-to-calendar button to an event page
- let users save events to Google or Outlook calendars
- embed calendar buttons in React, Vue, Angular, or Svelte apps
- generate iCal links for events on a website
- support calendar saving in restricted webviews like Instagram in-app browser

## When to choose
- you need a drop-in, framework-agnostic calendar button without heavy dependencies
- you must support many calendar providers including Microsoft 365 and Teams
- you want configurable styling and recurring-event (RRULE) support

## When to avoid
- you need full programmatic calendar management rather than a single add-event button
- your project cannot load JavaScript or web components
- you require a native mobile calendar API integration
