[ MANUAL ]
>> Epoch to Date — Enter a Unix timestamp in seconds (10 digits) or milliseconds (13 digits). Use quick adjustments to shift forward or backward in time.
> Date to Epoch — Pick a date/time from the calendar or type it manually. Choose Local or GMT, then convert to get epoch in seconds and milliseconds.
> Seconds to Human — Enter any number of seconds to see a plain-English duration, detailed breakdown, and equivalent unit conversions.
[ FAQ ]
>> Seconds vs. milliseconds? — Milliseconds are 1,000× more precise. JavaScript's Date.now() returns milliseconds; most Unix tools use seconds.
> Why 1970? — Unix time starts at January 1, 1970 00:00:00 UTC — a shared baseline adopted across operating systems.
> Does epoch include timezone? — No. Epoch values are absolute UTC counts. Timezone only affects how they are displayed to humans.
