About Timestamp Converter
The Timestamp Converter translates between Unix timestamps (seconds elapsed since January 1, 1970 UTC) and human-readable dates in both directions. A live counter shows the current Unix timestamp updating in real time.
Auto-detects whether your input is in seconds or milliseconds format, so you do not need to manually divide by 1000. Dates are displayed in both your local timezone and UTC for easy comparison.
Essential for developers debugging API responses, database records, JWT tokens, log files, and any system that stores dates as Unix epoch integers. All conversion runs locally in your browser with zero external dependencies.
Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp (also called epoch time) is the number of seconds that have elapsed since January 1, 1970 at 00:00:00 UTC. It is the standard way computers store and compare dates internally.
Does it support millisecond timestamps?
Yes. The tool auto-detects whether your input is in seconds (10 digits) or milliseconds (13 digits) and converts accordingly.
What timezone are dates displayed in?
Dates are shown in your local timezone with the UTC equivalent displayed alongside, so you can see both representations at once.
What is epoch 0?
Epoch 0 corresponds to January 1, 1970 00:00:00 UTC — the starting point of Unix time. Negative timestamps represent dates before this point.
Why do APIs and databases use Unix timestamps?
Unix timestamps are timezone-independent, compact (a single integer), easy to compare mathematically, and universally understood across programming languages and platforms.
