Time Zone Converter

Convert a clock time between two fixed UTC offsets.

Inputs

Adjust your data

Live
Key resultReview needed
20:00

Instant result based on your current inputs.

Interpretation

Review this scenario carefully. Fixed offsets do not identify daylight-saving transitions; confirm the correct offset for the place and date.

FormulaTarget time = source time − source UTC offset + target UTC offset, wrapped to 24 hours.
