Timestamp Converter

Epoch (Unix) time is the number of seconds (not milliseconds) since 1970-01-01 00:00:00 GMT (UTC). Values update in your browser.

Unix timestamp → human-readable

Enter seconds since the Unix epoch, or a 13-digit (or larger) integer for milliseconds. Fractional values are treated as seconds. Processing stays in your browser.

Human-readable date → Unix timestamp

Paste or type a date your browser understands (for example ISO 2024-06-01T12:00:00Z or 2024-06-01). The result is whole Unix seconds (fractional seconds are truncated).
