Compare time zones across the world, free. World Time is a visual time-zone comparison tool: add cities or zones and see their local times side by side as hour tiles, so you can instantly spot the overlap for a meeting across continents. It uses the IANA time-zone database for accurate offsets and DST, and runs entirely in your browser.
It shows each location's day as a row of hour tiles with column highlighting, so the working-hours overlap across zones is obvious at a glance. 100% free, no registration, and complete privacy — everything runs locally in your browser, so your data never touches a server.
Each location is a row of hour tiles, making it easy to scan day, night, and overlapping hours.
Add multiple cities/zones and arrange them to compare the times you care about.
Offsets and daylight-saving transitions follow the IANA database, so comparisons stay correct year-round.
Everything runs in your browser; nothing is uploaded.
Add each participant's city, then look for the column where every row falls within working hours. The hour-tile layout makes the shared daytime window easy to spot without doing offset math.

No. The tool runs entirely in your browser; the cities you add and the times are never sent to a server.
