Convert between Unix timestamp and readable date
The timestamp converter is an indispensable tool for developers, system administrators, data analysts, and IT professionals for converting between Unix timestamp (seconds since January 1, 1970) and readable dates in ISO 8601 and local format. Essential for web application debugging, server log analysis, database synchronization, API development, automated task scheduling, and any work involving date and time management in computer systems.
The tool converts bidirectionally between numerical and readable time representations:
Select the conversion mode: timestamp to date or date to timestamp.
Enter the timestamp value (number) or date in readable format depending on the selected mode.
Click 'Convert' or use the 'Use current date' button to get the current timestamp.
Copy any of the resulting formats (Unix, ISO 8601, formatted date) to use in your application.
This tool is fundamental in development and system administration:
Developers debugging APIs who need to understand timestamps in logs or JSON responses.
System administrators analyzing server logs with Unix timestamps who need readable dates.
Data analysts working with datasets that include timestamps and need to convert them for analysis.
Application developers implementing calendar functions who need to convert between formats.
Unix timestamp is UTC (no timezone). Always consider timezone when displaying dates to users.
Timestamp 0 represents January 1, 1970 00:00:00 UTC, known as 'Unix Epoch' or Unix epoch.
JavaScript uses milliseconds (13 digits), many systems use seconds (10 digits). Divide JS timestamps by 1000.
It's the number of seconds elapsed since January 1, 1970 00:00:00 UTC (Unix Epoch). It's universal and doesn't depend on timezone, which is why it's used in distributed systems.
That means it's in milliseconds (JavaScript). Divide by 1000 to get the standard Unix timestamp in seconds (10 digits). Multiply by 1000 for the reverse conversion.
32-bit systems can't represent timestamps after January 19, 2038 (2,147,483,647 seconds). 64-bit systems solve this until the year 292 billion.
