Time Zone Converter — Compare Times Across Cities

Time Zone Converter & Meeting Planner

Planning a meeting across time zones? Each city has its own timeline strip showing all 24 hours in local time. Click any hour on any strip — all other strips instantly highlight the same moment. Green cells are business hours (9 AM – 5 PM).

The business hour overlap calculator tells you exactly how many shared working hours exist. All calculations use daylight saving time from the browser's Intl API.
