🌍World Time Buddy — Time Zone Converter & Meeting Planner

Compare time zones around the world

This free world time zone converter helps you find the best overlapping hours across cities so you can schedule meetings, calls, webinars, and gaming sessions without confusion. Pick any date and time in your home zone, then read every other city's local time in the aligned columns. Daytime and night-time hours are color-coded so working hours are easy to spot at a glance.

Click any hour cell to move the reference point forward or backward in time — perfect for planning a future meeting or checking what time a past event happened elsewhere. Add cities by searching or by clicking dots on the interactive world map. Your selected zones are saved in your browser, and everything runs locally with no sign-up and no data leaving your device. Daylight saving time transitions are handled automatically.
