How the Time Difference Calculator Works
Select any two cities from the dropdowns above and the calculator instantly shows the exact hour difference between them. All results are DST-aware — when either city is observing daylight saving time, the offset adjusts automatically so you always get the correct current difference, not a static UTC comparison.
Why Time Differences Matter for Remote Teams
Knowing the exact time gap between two cities helps you schedule calls during overlapping business hours, set accurate deadlines, and avoid the common mistake of booking a meeting at 3 AM for a colleague. Use the meeting tip shown after each calculation to find the best shared window for both locations.
