UTC-first overlap finder

Find a humane half hour.

All 30-minute starts within this UTC date are checked. Results show local dates, including next-day boundaries. Uses your browser’s IANA timezone data.

Same-day work windows only; overnight windows rejected. Weekends, holidays and calendar conflicts are NOT excluded. This never books a meeting.

The downloadable skill is a detailed conversational workflow for ChatGPT or Claude, not a native installation guarantee. This browser demo implements only the limited workflow described above.
