Scope, formats and limitations
Time-zone rules come from your browser’s Intl database and may lag political changes. Invalid daylight-saving gap times are rejected; repeated times require an explicit choice. Working-hour labels use Monday–Friday 09:00–18:00 across the entire meeting, not holidays or real attendee availability. Durations are 5–480 minutes. Calendar export is a single UTC event without attendees, invitations, recurrence or reminders. No invite is sent automatically. Dates supported: 1900–2100.
