Easily convert Unix timestamps into human-readable dates. Decode epoch seconds or milliseconds into Local Time, UTC, and ISO 8601 formats instantly.
If you've ever looked at a database log or an API response and seen a long string of numbers like 1715634000, you've encountered Unix time. While computers love this format because it's just a simple integer, humans find it impossible to read. Our Unix Time to Date converter bridges that gap, allowing you to translate those seconds into a meaningful date and time.
Unix time, also known as Epoch time, represents the number of seconds that have passed since 00:00:00 UTC on January 1, 1970. It is the standard way systems track time without worrying about time zones or daylight savings in the underlying data. Whether you are using our Unix Timestamp Converter Online or debugging a script, understanding this format is essential for modern development.
Converting time shouldn't be a chore. Simply paste your number into the input field. The tool detects changes in real-time and updates the display. You can also click the "Current Time" button to see the live Unix timestamp for right now. This is particularly helpful when you need to generate a timestamp for testing purposes or when using the JavaScript Keycode Checker to debug event timings.
This usually happens if you are using milliseconds in a field expecting seconds. If your timestamp is 13 digits long (e.g., 1678900000000), make sure to select the "Milliseconds" unit in the dropdown menu.
Unix time traditionally ignores leap seconds. Each day is treated as having exactly 86,400 seconds. This tool follows the standard POSIX conversion used by most programming languages.
The "Year 2038 problem" affects 32-bit systems where the timestamp integer overflows. However, modern browsers and this tool use 64-bit floats for numbers, meaning it can accurately convert dates far beyond 2038.
