Event 1
How this works — and why it's private
- Each event becomes a standard VEVENT block in an .ics file — the same format Google Calendar, Apple Calendar and Outlook already import.
- Times you enter are converted to UTC so the event lands at the correct local time for whoever opens it.
- Reminders are saved as VALARM blocks. Repeating events use RRULE so calendars can extend them automatically.
