About Multi Timezone Planner

Multi Timezone Planner helps you compare schedules across several cities using live clocks, running seconds, and a shared 24-hour planning strip. Select the correct IANA timezone identifier (for example, America/New_York), not a city name, because city names may not be in the supported list.

Pick overlap windows between North America, Europe, and Asia quickly.
Validate launch and handoff times with timezone-aware hour mapping.

FAQ

Does Multi Timezone Planner fetch timezone data from a server?

Time conversion and clock updates run locally using your browser Intl timezone database. Layout and timezone rows are saved in your browser.

Can I add more than two timezones?

Yes. You can add and remove multiple IANA timezone rows and compare them in one timeline.
