Compare a meeting in several cities, catch daylight-saving clock changes, and download a calendar file with one unambiguous UTC start and end.

Your files, pasted data and meeting details are processed in this browser. No account or upload is needed. Downloaded results can contain your input; review them before sharing.

One meeting, 5–480 minutes, dates from 1970 to 2100, 16 available time zones. Uses your browser’s time-zone rules. No recurring events, attendee availability, holiday calendar or invitations.

Choose the date and the organiser’s time zone. Nonexistent spring-forward times are rejected. Repeated fall-back times require an explicit earlier/later choice. Work-hour hints assume weekdays 09:00–18:00, not local holidays or personal schedules.

A 60-minute meeting on 15 October 2026 at 09:00 in New York starts at 13:00 UTC, 14:00 in London, 15:00 in Berlin and 21:00 in Shanghai.

Does the calendar download send invitations?

No. It creates an .ics file on your device. You choose whether to import or share it; the tool contacts no attendees or calendar accounts.

Why can a local time be invalid or occur twice?

Daylight-saving changes can skip a clock interval or repeat it. The tool rejects skipped times and asks you to choose the earlier or later occurrence for repeated times.
