Calendar Event Generator
Make a calendar file for an event
Title, time, location, a reminder and an optional recurrence — out comes a valid .ics file to download, plus a Google Calendar link for people who will not.
How this is worked out
- The file is built in your browser and downloaded directly. Nothing about the event is transmitted anywhere.
- Lines are folded at 75 octets as the spec requires, which is what stops a long description failing to import.
Questions people ask
The things that come up about calendar event generators, answered plainly.
What is an .ics file?
The iCalendar format from RFC 5545 — a plain-text file every calendar application can import. Attaching one to an invitation email is how an event gets into someone's calendar without them retyping it.
Why does my event import at the wrong time?
Almost always because the file used a local time with no zone. This generator writes times in UTC with a Z suffix, which is unambiguous everywhere.
