About Timezone Converter
Timezone Converter is a free, browser-based tool that compares the current time across multiple cities and helps you find overlapping working hours for meetings. The time conversion and share-link creation run in your browser, while city search uses the site's timezone API.
It shows several timezones side by side on a 24-hour timeline so you can see, at a glance, when people in different regions are awake or at work. It is useful for remote teams, scheduling international calls, or checking the gap between two locations.
By default it runs in live mode and updates every second. You can drag the timeline or pick a specific time to preview a future meeting slot, add or remove cities, reorder them, and adjust each city's working hours. The current setup can be encoded into a shareable URL so others open the exact same view.
Working-hour highlights use a general 9-to-18 schedule and do not account for public holidays or team-specific policies, so treat them as a guide. Time math and the share URL stay on your device; only the city and timezone search sends a query to the server.
Frequently asked questions
- Does this work offline or send my data anywhere?
- Time conversion and the shareable URL are computed entirely in your browser. The only network request is the city and timezone search, which queries the site's API for matching timezone records.
- How do I share a meeting time with others?
- Set the cities and a time, then copy the generated share URL. It encodes your timezone list and selected time, so anyone who opens the link sees the same configuration.
- Why are the highlighted working hours wrong for my team?
- The highlights default to a 9-to-18 schedule that you can adjust per city, but they do not know about local holidays or your team's specific hours, so verify against your own calendar.
