Frequently asked questions
How do I find the time difference between two cities?
Enter the names of both cities in the form above and click "Check Time Zones". We look up the UTC offset for each city's IANA timezone and subtract them to give you the exact hour difference, accounting for Daylight Saving Time where applicable.
Does the calculator account for Daylight Saving Time?
Yes. We use each city's full IANA timezone identifier (for example "America/New_York" or "Europe/London"), which includes DST rules. The result always reflects the current offset at the time you run the query.
Why can two cities in the same country have different UTC offsets?
Large countries such as the United States, Russia, or Brazil span multiple geographic timezones. A city in California (UTC−8/−7) and a city in New York (UTC−5/−4) are in the same country but differ by 3 hours. Some countries also choose non-standard offsets like UTC+5:30 (India) or UTC+5:45 (Nepal).
What is the best time to schedule a call between two cities in different timezones?
Once you know the hour difference, aim for an overlap during normal working hours (09:00–18:00) in both locations. For example, if London is 5 hours ahead of New York, a 14:00 London call lands at 09:00 in New York — acceptable for both parties. Use the result page to see the current local time in each city before booking.
