About this tool

Generate a single-event .ics calendar file that any major calendar app - Google Calendar, Outlook, Apple Calendar, Fastmail, Proton - can import in one click. Useful for sending event invites, embedding RSVP links, or backing up a one-off appointment.

Times are encoded in UTC so the recipient's calendar will display the event correctly in their own time zone.

Features

  • iCalendar (RFC 5545) compliant
  • Title, start, end, location and description
  • UTC time encoding for cross-timezone reliability
  • Live preview of the .ics source

How to use it

  1. Enter the event title and start/end times.
  2. Optionally add a location and description.
  3. Click Download .ics and attach it to an email or host it on a page.

Will the time be correct for my recipient?
