How does the time zone difference calculator work?
Select two cities or time zones from the dropdown lists, and the calculator instantly shows the current time in each location plus the exact time difference between them. It uses standard UTC offsets to compute the hours and minutes ahead or behind. Perfect for scheduling international calls, planning travel, or coordinating remote teams across different parts of the world.
