How do I calculate the time difference between two cities?
Quick Answer: To find the time difference between two cities, check each city’s current UTC offset, then subtract one from the other. The result tells you how many hours apart they are.
Each city’s local time is set by its offset from Coordinated Universal Time (UTC). This offset can change with daylight saving time, so use the current offset for accuracy.
For example, if City A is UTC+3 and City B is UTC-5, subtract -5 from 3, giving 8 hours difference. That means City A is 8 hours ahead of City B.
