What is Unix time?
Unix time (also called Epoch time) counts the seconds since January 1, 1970 at 00:00:00 UTC. It's used in virtually every programming language, database, and API to represent moments in time as a single number — timezone-independent and easy to compare.

What is a Unix timestamp?
A Unix timestamp (also called Epoch time or POSIX time) is the number of seconds that have elapsed since January 1, 1970 00:00:00 UTC. It's a universal way to represent a moment in time as a single integer, used widely in programming, databases, APIs, and logs.
What formats can I input?
You can enter a Unix timestamp in seconds (e.g., 1700000000) or milliseconds (e.g., 1700000000000), an ISO 8601 string (e.g., 2023-11-14T22:13:20Z), or any human-readable date string (e.g., 'Nov 14, 2023 10:13 PM'). The tool auto-detects the format.
How does it detect seconds vs milliseconds?
If the number has fewer than 13 digits (less than 10 trillion), it's treated as seconds. Otherwise, it's treated as milliseconds. This covers all dates from 1970 to 2286.
What timezone does it use?
The tool shows both UTC and your local timezone. The live clock runs in your browser's timezone. All conversions correctly handle timezone offsets.
Does it work offline?
Yes. All timestamp math runs 100% in your browser using JavaScript's Date object. No server requests, no data uploaded.
What's the Year 2038 problem?
Systems using 32-bit signed integers for Unix timestamps will overflow on January 19, 2038. This tool uses JavaScript's 64-bit floats, which can represent dates far beyond 2038 without issues.
