Updates every second. This is the current Unix timestamp (seconds since 1970-01-01T00:00:00Z UTC).
Values ≥ 1012 are treated as milliseconds; smaller values as seconds.
Convert Unix epoch timestamps to dates online, free. A Unix timestamp (epoch time) is the number of seconds since 1970-01-01 00:00:00 UTC — the time representation used across databases, logs, APIs, and programming languages. This converter turns a Unix timestamp into a human-readable date (and back), handling both seconds and milliseconds, entirely in your browser.
It converts both ways — timestamp to date and date to timestamp — and auto-detects seconds vs milliseconds, so you don't misread a value by a factor of 1000. 100% free, no registration, and complete privacy — everything runs locally in your browser, so your data never touches a server.
Convert a Unix timestamp to a readable date, or a date to a Unix timestamp.
Handles 10-digit (seconds) and 13-digit (milliseconds) timestamps so JS Date.now() values work too.
Shows the result in both UTC and your local time zone to avoid off-by-hours mistakes.
Conversion runs locally; nothing is uploaded, logged, or stored.
A Unix timestamp is the number of seconds elapsed since the Unix epoch — 00:00:00 UTC on 1 January 1970. It's a compact, time-zone-independent way to store an instant in time, used widely in programming, databases, and APIs.
Both are common: classic Unix time is in seconds (a 10-digit number around 1.7 billion today), while JavaScript's Date.now() returns milliseconds (13 digits). This tool detects the magnitude so you don't misread a value by 1000×.
A Unix timestamp encodes an instant in UTC with no time-zone offset. This converter shows both the UTC date and your local equivalent so you can use whichever you need.
Systems that store Unix time in a signed 32-bit integer overflow on 19 January 2038, wrapping to a negative number. Modern systems use 64-bit timestamps, which avoid the issue for billions of years.
No. The conversion runs entirely in your browser — nothing is sent to a server.
