How This Works
This converter uses each city's actual IANA time zone rules — not a fixed offset — so daylight saving time transitions are handled automatically and correctly for today's date.
Formula
Target Time = Source Time + (Target UTC Offset − Source UTC Offset)
Example
9:00 AM in New York (UTC−5) is 2:00 PM in London (UTC+0) — a 5-hour difference. The exact gap shifts slightly through the year as different regions enter and exit daylight saving time.
