How it works
Write a VCALENDAR containing one VEVENT, escape text separators and fold long UTF-8 content lines. End time must follow start time.
The default event runs from 12:00 to 13:00 UTC on January 1, 2026: 3600 seconds.
Limits
One UTC event only. Supply your own stable UID and revision timestamp. No recurrence, attendees, invitations, timezone conversion or external calendar access.
