How to use iCal Event Generator (.ics)

Fill in the event title, date, start and end time, location and description, choose a timezone and reminder, then download the .ics file or copy the raw text.

Frequently asked questions

Will the .ics file open in Google Calendar and Outlook?

Yes. The output follows RFC 5545 with the required VCALENDAR and VEVENT blocks, CRLF line endings, a unique UID and a DTSTAMP, which is exactly what those apps validate. Attach it to an email or import it from the calendar's settings.

How are timezones handled?

Choose UTC and the times are written with a trailing Z, which every client interprets identically. Choose a named timezone and the event is written as a floating local time with a TZID, so 10:00 stays 10:00 for attendees in that zone.

Can I add a reminder?

Yes. Pick a reminder interval and a VALARM block is added with a DISPLAY action and a negative trigger, so the calendar app pops a notification that many minutes, hours or days before the event starts.
