How this tool works
Input is explicitly UTC, not the computer’s local wall time. Offsets and daylight saving use the time-zone database bundled with your browser. Update the browser for the latest rule changes.
Inputs and results stay in this page’s memory until you leave or reset it. Downloads remain on your device. Review the result before using it in another application.
