What is Time Zone Map?

Time Zone Map shows every world time zone on an interactive map. Click any region to see its current local time, UTC offset, and DST status. Compare several zones side by side and plan meetings that work for everyone.

The map covers every IANA time zone with daylight saving rules built in, so pinned cities reflect their real local time including DST transitions. Your own zone sits at the top as a live local clock, the date picker projects every time to a chosen day, and the 24-hour comparison strip highlights overlapping working hours (adjustable, 09–17 by default). The export TSV is ready to paste into Notion, Google Sheets, or a Slack message.

How to use

1. Explore the map to see time zone boundaries. Hover over or click a region to view its current time.
2. Pin multiple cities or time zones to compare their current times side by side.
3. Use the time slider to set the hour of day, or pick a date to project every pinned zone to a specific future day — then read off the overlapping working hours.

When to use

• Scheduling a recurring all-hands across at least three offices on different continents.
• Booking a remote interview when the candidate is somewhere you've never had to convert from.
• Planning travel that crosses three or more zones to spot the days the calendar shifts under you.

Result

A remote team manager pins New York, London, Tokyo, and Sydney to plan a standup meeting. Using the time slider, they find that 9 AM EST works for all zones within business hours.

FAQ

Does the map handle daylight saving time correctly?

Yes. Each city is anchored to its IANA zone (America/New_York, Europe/Paris, etc.) and the JavaScript Intl APIs resolve the offset for the current date, including DST transitions. Pinned cities in São Paulo, Phoenix, or Sydney all reflect their real wall-clock time.

How do I find a city that isn't in the default list?

Use the search box at the top of the map. Typing a partial name (e.g. 'Belgrade' or 'Casablanca') matches against the city list. If nothing comes up, search the time zone identifier instead (Europe/Belgrade) and pin a representative city from the same zone.

What does the 24-hour comparison strip show?

It plots each pinned zone's hours across a 24-hour band starting at UTC. The shaded cells on each row mark your chosen working window (09:00–17:00 by default, adjustable with the start/end pickers above the grid), and a top row labelled 'Everyone awake' lights up the UTC hours when every pinned city falls inside that window at the same time. Half-hour zones like Mumbai (+5:30) and Kathmandu (+5:45) are scored against their precise local time, so a cell that reads 09 stays correctly shaded as a working hour when the real local clock is 09:30 or 09:45. Hover any cell to see the exact local HH:MM.

Can I export the comparison for a calendar invite?

Download the TSV with one row per pinned city: name, IANA zone, local time at the slider position, and current UTC offset. Most calendar tools accept that pasted into the description, and Google Sheets opens TSV directly.

How far ahead can I plan a meeting?

Two controls work together. The time slider nudges the hour of day a few hours either way for quick standup planning, and the date picker jumps the whole comparison to a specific future calendar day — handy for scheduling next Tuesday or a trip weeks out. Every pinned time, the offsets, and the overlap row recompute for the chosen date, so daylight-saving changes between now and then are accounted for.
