A real iCalendar file, made locally

    
This produces a standards-compliant .ics (RFC 5545) with a unique UID, timestamp, proper text escaping and 75-character line folding — the same format Apple Calendar, Outlook and Fantastical expect. Everything is assembled in your browser, so your meeting details never touch a server. Prefer Google? The “Add to Google Calendar” button opens a prefilled event in a new tab.
