Preview an ICS calendar file

Open an .ics calendar file in the web app to read its events. The preview is read-only. It does not subscribe you to a live calendar, send an RSVP or add events to another calendar just by opening the file.

Steps: browse the calendar

1. In Files, open the calendar’s filename or choose View from its menu.
2. For a calendar with several events, use Agenda to read the event list or Month to see a calendar grid. A file containing one non-repeating event opens a Details card instead.
3. Use Today, the previous and next month buttons, or Show earlier events and Show more events to move through the dates.
4. Enter a word in Search events to find matching event titles, places or descriptions. Clear the search to return to the full list.
5. Select an event to inspect its time, place, repeat pattern, description, organizer and guests when those details exist in the file.
6. Select Source if you need to inspect the original calendar text.

Timed events use your browser’s timezone. When an event’s original timezone gives a different time, the details also show that original time. All-day events are shown as dates. Check the timezone before comparing the preview with an invitation or another calendar app.

Use an event outside dosya

Download event saves an ICS file for the selected event. Add to Google Calendar opens Google Calendar to prepare an event there. Review the details in Google Calendar before saving. Use the file viewer’s download control to get the original whole calendar.

Guest response labels and reminders describe information already in the file. The viewer does not send a new response or schedule a reminder on your device. Join call and location links open the external addresses provided by the event.

Missing events or a text fallback

The web calendar preview accepts files up to 40 MiB. Larger files offer a download fallback. An unreadable file or one with no usable events can open as text instead.

The preview limits how far recurring events are expanded and how many search results are shown. Unusual repeat rules may not display every occurrence. If a far-future event is missing, or an important date looks wrong, download the original and check it in your calendar application. Renaming another file to .ics does not turn it into a calendar.

For other formats, see previewing files. For the original calendar file, follow downloading files.

Expected result

A readable calendar displays events and their available details. Browsing leaves the original file unchanged and does not add events to an external calendar.
