What is a Unix Epoch?

      
Unix epoch time is the number of seconds elapsed since January 1, 1970 00:00:00 UTC. Also called Unix time, POSIX time, or Unix timestamp, it is the universal standard for storing time in software systems. Every operating system, database, and programming language has built-in support for it.

    

    

      
How to convert epoch to date

      
Paste any Unix timestamp into the converter above and click Convert. Timestamps are automatically detected as seconds (10 digits), milliseconds (13 digits), microseconds (16 digits), or nanoseconds (19 digits). Results are shown in your local time, UTC, ISO 8601, and relative format.

Developer notes for timestamp conversion

    

      
Choosing the right timestamp unit
Most Unix tools, database exports, and backend APIs use epoch seconds. Browser APIs such as JavaScript Date use milliseconds. A current Unix seconds value is usually 10 digits, while a current JavaScript timestamp is usually 13 digits. This converter detects common units, but production APIs should still name fields clearly, such as created_at_unix_seconds or expires_at_ms.

      
UTC first, local display second
A Unix timestamp identifies one instant on the UTC timeline. Timezones only change how that instant is displayed to a person. Store the instant once, then format it for New York, London, Tokyo, or any other IANA timezone at the presentation boundary.

      
Debugging wrong dates
If a converted date is near 1970, seconds were probably passed into a millisecond API. If it is thousands of years ahead, milliseconds may have been treated as seconds. If it is off by several hours, compare the UTC value before checking local timezone formatting.

Timestamp converter FAQ

    

      
Should I store Unix time or ISO 8601?
Use Unix time when you need compact numeric comparison, queue delays, TTL values, or log sorting. Use ISO 8601 when humans inspect the value or when an API benefits from an explicit UTC suffix or offset.

      
Why does timezone conversion not change the epoch?
The epoch value is the same moment everywhere. Only the calendar representation changes. Midnight in one region may be the previous or next day somewhere else, but the underlying timestamp stays stable.

      
Where can I learn the details?
Start with the Unix timestamp guide, then compare milliseconds vs seconds and Unix time vs ISO 8601.
