ICS Calendar Event Generator
Generate RFC 5545 ICS event files locally, with support for time zones, locations, descriptions, participants, and durations.
How to use the ICS calendar event generator
ICS The calendar event generator processes input only in the current browser; it does not upload, connect to the internet, or save user data.
Input content
Enter a title, start/end times, time zone, location, and description.
Select a processing method
Process escaping, line wrapping, UID, UTC/TZID, and optional attendee fields.
Check and export
Preview and download .ics files in the browser without sending calendar invitations.
Limitations and Notes
- Does not generate a complete VTIMEZONE, nor connect to any calendar service.
- Calendar clients differ in their support for time zones and optional fields; check events after importing.
- The tool only provides locally processed results; important configurations, secrets, documents, and published content must still be reviewed in the target environment.
FAQ
Will the input be uploaded to a server?
No. The page only uses browser memory, the local file API, and local resources already provided with the site.
Will it be added to my calendar automatically after generation?
No. The tool only downloads the local ICS file, which users must open or import themselves.
Why do the results still require manual review?
Edge-case syntax, regional standards, third-party readers, and target runtime environments may differ; the tool does not replace final validation.
