Unix Timestamp Converter
Convert Unix timestamps to human-readable dates and vice versa. Live timestamp display, seconds and milliseconds modes. Free online tool, no signup required.
Why Use a Unix Timestamp Converter?
Unix timestamps (also called epoch time) are widely used in programming, databases, and APIs to represent dates as simple integers. However, they're not human-readable. Our converter bridges the gap, letting you quickly translate between timestamps and readable date formats. The live timestamp display is especially useful for debugging time-sensitive applications.
Key Features
- Live updating current timestamp display
- Seconds and milliseconds modes
- Bidirectional conversion: timestamp to date and date to timestamp
How to Use
- View the current Unix timestamp at the top (updates live)
- Enter a timestamp to convert it to a readable date, or enter a date to get its timestamp
- Toggle between seconds and milliseconds mode as needed
Technical Details
Unix timestamps represent the number of seconds (or milliseconds) elapsed since January 1, 1970 00:00:00 UTC (the Unix epoch). Our tool uses JavaScript's Date object for conversions, which internally stores time as milliseconds since epoch. All conversions happen client-side in your browser.
FAQ
What is a Unix timestamp?
A Unix timestamp is the number of seconds that have elapsed since January 1, 1970 (UTC), excluding leap seconds. It's also called epoch time or POSIX time.
When should I use milliseconds vs seconds?
JavaScript and many modern APIs use milliseconds, while Unix/Linux systems traditionally use seconds. Check the documentation of the system you're working with.
