Timezone Meeting Planner

This timezone meeting planner finds the hour that works for everyone. Your own time zone is already on the board — add the people you want to meet from a searchable list of about 78 cities, and a single draggable marker shows each person's local time side by side. Slide it across the day and watch every row update instantly.

Each timeline is colour-coded into three bands so a good slot is obvious at a glance: green Working hours (09:00–18:00), amber Stretch hours (07:00–09:00 and 18:00–22:00) and dark Asleep hours (22:00–07:00). An overlap meter shows what share of participants are inside working hours at the marker, and "Jump to best time" snaps to the slot that puts the most people in their working day while waking the fewest.

All of the maths runs in your browser using your device's built-in IANA time-zone database via the Intl API, so daylight-saving changes and awkward offsets — India's +5:30, Nepal's +5:45, Adelaide's +9:30 — are always exact, with no server and nothing sent anywhere. When you have picked a time you can copy a clean summary list or download a standard .ics calendar invite to drop straight into Google Calendar, Outlook or Apple Calendar.
