Convert timestamp

Enter a Unix timestamp in seconds or milliseconds, or pick a local date & time.

10 digits = seconds · 13 digits = milliseconds

Epochs & time reference

Unix epoch — January 1, 1970 00:00:00 UTC. Standard for most programming languages and APIs.

Milliseconds (ms) — Unix time × 1000. Used by JavaScript Date.now(), Java System.currentTimeMillis(), and PHP microtime(true).

Windows FILETIME / LDAP — 100-nanosecond ticks since January 1, 1601 UTC. Used by .NET and Active Directory.

NTP epoch — Seconds or milliseconds since January 1, 1900 00:00:00 UTC.

.NET DateTime ticks — 100-nanosecond ticks since January 1, 0001 00:00:00 UTC.

GPS time — Seconds since January 6, 1980 00:00:00 UTC (approximate; GPS-UTC offset not applied).

Julian day — Continuous day count used in astronomy. JD 2440587.5 = Unix epoch.

UTC vs GMT — For software and APIs they are effectively identical. UTC is the modern atomic-time standard; GMT is the legacy solar-time name still used in HTTP headers.

Leap seconds — UTC occasionally adds a leap second to stay aligned with Earth's rotation (e.g. 23:59:60). Most Unix timestamps ignore leap seconds and count fixed 86400-second days.
