Your next Add to Calendar Button

The convenient JavaScript Web Component, which lets you reliably create beautiful buttons, where people can add events to their calendars.

For everybody, who wants to include a button at their website or app, which enables users to easily add a specific event to their calendars. It's main goal is to keep this process as easy as possible at maximum compatibility. Simply define your button configuration and everything else is automatically generated by the script. Supporting calendars at Apple, Google, Microsoft (365, Outlook, Teams), Yahoo, and generic iCal.

The script, since it is a web component, integrates easily with any usual HTML webpage (VanillaJS way) as well as popular JavaScript frameworks and libraries like Angular, React, Vue, Svelte, and more.

Works with all modern browsers (Chrome, Edge, Firefox, Safari) on Windows, Mac, Android, and iOS as well as rather restricted webview environments like the Instagram in-app browser.

<add-to-calendar-button
  name="Add the title of your event"
  startDate="2022-02-21"
  options="['Google']"
  timeZone="America/Los_Angeles"
/>

  endDate="2022-03-24"
  startTime="10:13"
  endTime="17:57"
