Epoch time made readable

A Unix timestamp counts the seconds since January 1, 1970, 00:00 UTC. Paste one and the converter shows the date in ISO 8601, UTC, your local time and any time zone you pick — Eastern, Central, Mountain, Pacific, London, Tokyo and more — plus a friendly relative time like “in 3 days” or “2 years ago”.

It auto-detects the unit from the number of digits: 10 digits for seconds, 13 for milliseconds (JavaScript's Date.now()), 16 for microseconds and 19 for nanoseconds. Going the other way, pick a date and time, choose the time zone it's in, and get the timestamp in seconds and milliseconds. A live clock shows the current Unix time.

How to convert a Unix timestamp

  1. 1

    Paste the timestamp

    Seconds, milliseconds or smaller units.

  2. 2

    Choose a time zone

    Your own, UTC or a major city.

  3. 3

    Read the date

    ISO, UTC, local and relative formats.

  4. 4

    Or convert a date

    Pick a date and time to get its timestamp.

Key features

  • Unit auto-detection

    s, ms, µs and ns by digit count.

  • US and world time zones

    Daylight saving handled automatically.

  • Both directions

    Timestamp to date and date to timestamp.

  • Code snippets

    Current timestamp in 12 languages and databases.

Common uses

  • Reading logs: Convert epoch times in server and app logs.
  • Debugging APIs: Check exp and iat claims or created_at fields.
  • Scheduling: Find the timestamp for a launch or deadline in another time zone.

Tips and good to know

  • Timestamps are the same everywhere; only their display changes with the time zone.
  • Decoding a token? The JWT Decoder converts its exp and iat claims automatically.

Frequently asked questions

What is the current Unix timestamp?

It's shown live at the top of the page and updates every second, in both seconds and milliseconds.

Seconds or milliseconds?

Unix time is traditionally in seconds (10 digits today). JavaScript and many APIs use milliseconds (13 digits). The converter detects which one you pasted.

What is the Year 2038 problem?

Systems that store Unix time in a signed 32-bit integer overflow on January 19, 2038. Modern systems use 64-bit time and aren't affected.

Does Unix time include leap seconds?

No. Every day is treated as exactly 86,400 seconds.
