ICS feeds
Owl generates standards-compliant iCalendar (.ics) output so visitors can subscribe to your calendars or add a single event to their own. This is free in Lite — many plugins charge for it.
Calendar feeds
Every calendar exposes a subscribable feed at:
/owl/calendar/.ics
Point Google Calendar, Apple Calendar or Outlook at this URL and the feed stays up to date. Link to it from your templates:
Single-event downloads
Offer an “Add to calendar” link for one event with:
/owl/event/.ics
How recurrence is exported
Owl emits one VEVENT per materialised occurrence, each with a stable unique ID. This keeps feeds unambiguous across calendar clients — every instance, exception and override is represented as its own concrete event, so what subscribers see matches your site exactly.
