Time Zone Converter & Meeting Planner
Compare time zones and plan meetings across the world. Add any city by search, map click, or your own location, then drag the meeting time to see the local hour everywhere at once, with working hours highlighted.
What is a time zone comparison tool?
A time zone comparison tool shows the current local time in several places at once and lets you plan a meeting time that works across all of them. Add each participant’s city, pick a time, and see the corresponding local hour everywhere, with working hours highlighted so you can spot an overlap that suits everyone. It handles daylight saving automatically using each location’s official IANA time zone.
About timezones and IANA names
A timezone is the offset from Coordinated Universal Time (UTC) that a region uses for local clocks. The IANA timezone database (also called tz or zoneinfo) is the universal naming convention used by every major operating system, programming language, and cloud platform. Names follow Region/City format: Europe/Brussels, America/New_York, Asia/Tokyo. Storing the IANA name (not just the UTC offset) is the only way to handle daylight saving time and historical changes correctly.
How this tool works
Add a place by typing an address, clicking the map or using your location. A typed address goes to the EU-hosted MapAtlas geocoder, which returns its latitude and longitude. The tool then sends those coordinates to timeapi.io, a third-party time zone service, which returns the IANA time zone for that point. For a point you click or your own position, the MapAtlas geocoder also looks up the place name. Your own time zone, shown first, comes from your browser settings and is not sent anywhere. To resolve time zones from coordinates inside your own product, use the MapAtlas location APIs.
When you need this
Booking flows that need to display local check-in times, scheduling tools that compute meeting overlap across cities, IoT pipelines that timestamp events with the correct local zone, AI assistants answering 'what time is it in...', and any travel, logistics, or hospitality product that operates across borders. Every modern stack expects IANA names. Storing only a UTC offset will break the moment a region changes its DST rules, which happens somewhere on Earth almost every year.
