About this tool
Convert a date and time from one city’s time zone to another, including daylight saving time.
Uses the IANA time-zone database built into your browser: the local time is turned into an exact instant, then shown in the target zone with its offset on that date.
Formula: t_to = t_from − offset_from + offset_to
Example: Date = 2026-07-01, Time = 09:00, From time zone = Dubai, To time zone = New York → Time = 01:00, Date = 2026-07-01.
During a daylight-saving change, a local time that does not exist (or occurs twice) is resolved to the nearest valid instant.
