Time across UTC offsets Calculator

Convert a dated local time between explicit UTC offsets. This free time across utc offsets calculator shows the calculation and its assumptions so you can compare your own figures.

How the time across utc offsets calculation works

Subtract the source offset to get UTC, then add the destination offset.

Enter the offsets applicable to the chosen date. Named-zone daylight-saving rules and ambiguous local times are not inferred.

Using this calculator

  1. Enter your own figures in the labelled inputs. Keep the currencies, units and time periods consistent.
  2. Choose any applicable rate profile, pattern or assumption shown for this tool. Open additional inputs when relevant.
  3. Review destination date and destination time, then read the stated assumptions and eligibility conditions before using the result.
