How to Use the Time Zone Meeting Planner
The Travel Time Zone Planner makes scheduling across multiple time zones visual and fast. Instead of mentally converting time zones for each participant, you see all the business hours bars side by side — the teal overlap zone shows exactly when everyone is available.
Step 1: Add Your Cities
Type a city name in the search box — the planner includes over 100 major cities worldwide. The tool starts with New York and London pre-loaded as an example. You can add up to 8 cities. Remove any city by clicking the × button on its row.
Step 2: Read the Timeline
Each city gets a horizontal bar spanning 24 hours (midnight to midnight in UTC). The light teal zone shows when that city's business hours fall. The darker teal zone on any bar shows the overlap window — the time when all selected cities are simultaneously in their business hours. A red vertical line marks the current time.
Step 3: Adjust Business Hours
The default business hours are 9:00–17:00 local time in each city. If your team works 8:00–18:00 or you're scheduling across a broader window, adjust the Start/End time inputs. The timelines update immediately to reflect the new hours.
Step 4: Check the Overlap Summary
The Overlap Analysis card shows the exact window in UTC when all cities' business hours coincide, plus the local time equivalent for each city. For example, a 14:00–16:00 UTC slot means 9:00–11:00 in New York, 14:00–16:00 in London, and 15:00–17:00 in Berlin — a practical early-afternoon slot for transatlantic teams.
When There Is No Overlap
Locations spanning more than 14 hours of time difference (like San Francisco and Singapore) often have no overlapping business hours within a 9–5 window. In these cases, the planner suggests early morning or late afternoon options where one team member adjusts their working hours by 1–2 hours to find a shared slot.

FAQ
How do I use the time zone meeting planner?
Type a city name in the search box and click 'Add City'. The planner adds it to a visual timeline showing each city's business hours on a 24-hour bar. The overlap zone (where all cities' business hours align) is highlighted in teal.
Is this tool free?
Yes, the Travel Time Zone Planner is completely free with no signup required. All time zone calculations use your browser's built-in Intl API — no external services needed.
Is my data private?
Yes, all calculations run locally in your browser. No city data or preferences are sent to any server. Your schedule information stays completely private.
Does the planner account for daylight saving time?
Yes. The planner uses IANA time zone identifiers (like 'America/New_York') with JavaScript's Intl.DateTimeFormat API, which handles DST transitions automatically for all regions.
How many cities can I add?
You can add up to 8 cities for comparison. With more than 4-5 cities, finding overlapping business hours becomes challenging — the overlap window shrinks with each additional city.
What if there is no business hours overlap?
If no common business hours exist (e.g., New York and Tokyo have a very small or zero overlap during standard 9-5 hours), the tool will show a 'No common business hours' message and suggest early morning or late afternoon alternatives.
Can I change the business hours definition?
Yes, use the Start and End time inputs to set your preferred business hours window. Changing from the 9:00-17:00 default to, say, 8:00-18:00 may reveal additional overlap opportunities.
