How It Works

This tool runs entirely in your browser using vanilla JavaScript. No data is sent to any server. All conversions and calculations happen locally on your device, ensuring complete privacy.

EpochPilot uses the browser's built-in Intl.DateTimeFormat API and the IANA timezone database provided by your operating system. This means timezone conversions are always accurate, including Daylight Saving Time transitions.
