About the Time Zone Converter

This simplified time zone converter shifts a clock time by the difference in hours between two fixed UTC offsets. It does not account for daylight saving time changes, so double-check whether either zone is currently observing DST.

Formula: New time = Original time + (To Offset − From Offset), wrapped within a 24-hour clock, with any overflow reported as a day change

Useful for quickly figuring out a meeting time or flight arrival across two time zones expressed as UTC offsets, such as UTC-5 to UTC+9.
