Unix timestamp is the number of seconds since January 1, 1970 (UTC). This tool converts between Unix timestamps and human-readable date formats. Auto-detect treats values above 10,000,000,000 as milliseconds and everything else as seconds — or pick an explicit unit (seconds, milliseconds, microseconds, nanoseconds) for full control.
The Timestamp Converter turns Unix timestamps (the number of seconds since January 1, 1970 UTC) into human-readable dates and back again, right in your browser. Reach for it when you're staring at a raw epoch value in a log file, database row, API response, or JWT and need to know what date and time it actually represents. It runs entirely client-side, so the values you paste never leave your machine.
A Unix timestamp (also called epoch or POSIX time) is the number of seconds that have elapsed since 00:00:00 UTC on January 1, 1970, ignoring leap seconds. It's a compact, timezone-independent way for systems to store and compare points in time.
Yes, it's completely free with no sign-up, account, or usage limits. Convert as many timestamps as you need.
Yes. The converter runs 100% in your browser — the timestamps and dates you enter are never uploaded, stored, or tracked. This makes it safe for values pulled from internal logs or private systems.
That's almost always a seconds-vs-milliseconds mismatch. Unix time is measured in seconds, but many languages (like JavaScript's Date.now()) return milliseconds — a 13-digit value. Divide a millisecond value by 1000 to get the correct seconds-based timestamp.
Yes, it works in both directions: paste an epoch number to see the date, or enter a calendar date and time to get its Unix timestamp.
