Convert between Unix timestamps and human-readable dates in either direction, in seconds or milliseconds. All conversions use your browser's local timezone and run entirely on your device.
How it works
Unix timestamp is the number of seconds elapsed since January 1, 1970, 00:00:00 UTC (the "epoch"). Many systems use milliseconds instead; pick the matching unit.
Timestamp → date. Type a number; the readable local date and time appear instantly.
Date → timestamp. Type a date like
2026-08-07 12:00:00; the timestamp appears instantly.Ambiguity. A date you enter is read as your local time. To force UTC, enable the "Show UTC" option or append a
Z to an ISO value.
