Easily convert between Unix timestamps and human-readable dates. Unix time (also known as POSIX time or Epoch time) is a system for describing points in time, defined as the number of seconds that have elapsed since January 1, 1970 (UTC).
Epoch to Human
Paste any Unix timestamp (seconds or milliseconds) to see it converted instantly into Local Time, UTC, and ISO 8601 formats. The tool automatically detects the precision.
Human to Epoch
Select a date and time using the pickers to generate the corresponding Unix timestamp. This is essential for setting expiration times in tokens or database queries.
Did You Know?
The "Year 2038 problem" (also known as Y2K38) refers to the end of Unix time for 32-bit systems. On January 19, 2038, the signed 32-bit integer used to store the timestamp will overflow, potentially causing system failures. Modern 64-bit systems solve this, extending the limit billions of years into the future.

Understanding Unix Timestamps
Unix timestamps are fundamental to computing and are used extensively in databases, APIs, log files, and programming. Our converter helps developers, system administrators, and anyone working with time data to quickly translate between human-readable dates and Unix time.
Common Use Cases
- Database timestamps - Many databases store dates as Unix timestamps for efficiency
- API responses - REST APIs often return timestamps in epoch format
- Log analysis - Server logs frequently use Unix time for precise timing
- File metadata - File systems track creation and modification times as timestamps
Programming Language Examples
Different programming languages handle Unix timestamps differently. JavaScript uses milliseconds (Date.now()), while Python's time.time() returns seconds. PHP's time() also returns seconds. Our converter handles both formats automatically.
