About this tool
Generate a single-event .ics calendar file that any major calendar app - Google Calendar, Outlook, Apple Calendar, Fastmail, Proton, Thunderbird - can import in one click. Useful for sending event invites without needing to be in the same calendar ecosystem as the recipient, embedding RSVP links on a webpage, or backing up a one-off appointment as a portable file.
Times are encoded in UTC so the recipient's calendar will display the event correctly in their own time zone, with daylight saving handled automatically by their device. If you schedule a meeting at 14:00 Copenhagen time and send the .ics to someone in New York, their calendar will show it at 08:00 local time without anyone doing the math.
The .ics format follows RFC 5545, the same standard every serious calendar tool implements. Files generated here import cleanly across all major platforms - nothing proprietary, nothing locked to a single vendor, nothing that will stop working in three years.

Frequently asked questions
Not yet. This tool focuses on single events because the recurrence rules in RFC 5545 are surprisingly intricate ("second Tuesday of every other month, except December") and easier to set up in a real calendar app. For one-off events the .ics format is the right tool.
Yes. Times are stored in UTC; the recipient's calendar converts them to their local zone automatically, including daylight saving adjustments.
Yes. Attach the .ics with the MIME type text/calendar (most mail clients set this automatically based on the .ics extension). Recipients will see an Add to Calendar button when they open the message.
No. .ics files are self-contained - they describe the event in plain text and import into any calendar app on the recipient's device. No login, no third-party service, no tracking pixel.
