Unix Timestamp Converter

See the current Unix timestamp update live, convert any timestamp to a readable date, or turn a date back into a timestamp — in seconds or milliseconds.

How to use this timestamp converter

The panel at the top shows the current Unix timestamp updating every second, handy when you need a value to paste into a script or database query right now. To convert an existing timestamp, paste it into the second box — the tool automatically detects whether it's in seconds or milliseconds based on its length — and click Convert to see it as a local and UTC date. To go the other way, pick a date and time in the third box and convert it into both second and millisecond timestamps.

Why Unix timestamps matter

Unix time counts the seconds (or milliseconds) elapsed since January 1, 1970 UTC, and it's the backbone of how most systems store and compare dates internally — logs, databases, APIs and JWTs all lean on it. Because it's just a number with no timezone baked in, developers constantly need to translate it into something readable, or vice versa, when debugging or writing test data.
