About Timezone Converter
The Timezone Converter is a visual meeting planner designed for remote teams. It allows you to cross-reference multiple time zones simultaneously and calculate the UTC offset, making it easy to schedule across borders.
Coordinate global collaboration without the headache of mental math. Finding a slot that works for London, New York, and Tokyo is complex; this scheduler visualizes the overlap so you can pick a reasonable hour for everyone.
Add cities or zones to your list. Drag the time slider to see how the hour shifts for every location. The tool highlights business hours to help you avoid scheduling meetings in the middle of the night.
Under the Hood
Timezone calculations use `date-fns-tz` to handle IANA timezone identifiers accurately. When a source time is selected, it is normalized to UTC. Then, this UTC timestamp is projected into target timezones, accounting for Daylight Saving Time (DST) shifts specific to each region's historical and future rules (via the bundled timezone database).
