How the calendar button works

The calendar button detects the visitor's OS and preferred calendar app and routes to:

• Google Calendar (web)
• Apple Calendar (macOS, iOS, iPadOS — via .ics)
• Microsoft Outlook (desktop or web)
• Office 365 Calendar
• Yahoo Calendar

Behind the scenes we generate an iCalendar (.ics) entry or a deep link with all event data: title, description, location/URL, start, end, time zone, reminder offset.

What the visitor sees

Depending on embed style:

• Button — click opens a calendar chooser
• Dropdown — direct choice, no extra step
• Link — plain text link
• Email link — compatible with all email clients

No sign-up required

Visitors do not need a SpreadEvent account. The button works without RSVP — in that case only the calendar entry is created.
