Convert a Unix timestamp (epoch time) into a readable date, or turn any date into its Unix timestamp. Unix time counts the seconds since January 1, 1970 UTC, and it is the format most APIs, databases and log files use internally because it is compact and timezone-independent. This converter handles both seconds and millisecond timestamps automatically, and shows you the result in both your local time and UTC so there is no ambiguity. Enter a number to decode it, or pick a date to encode it. The current live timestamp ticks at the top for quick reference. All conversion happens in your browser.
