Unix Timestamp Converter
Convert Unix timestamps to readable dates and convert dates back to timestamps.
Unix timestamps and how they work
A Unix timestamp (also called Epoch time) is the number of seconds elapsed since January 1, 1970, 00:00:00 UTC — the Unix epoch. This timezone-independent integer is used in databases, APIs, log files, and file systems because it is compact and trivially sortable.
When you see a timestamp like 1700000000, that corresponds to November 14, 2023. Most programming languages provide built-in functions to get the current timestamp: Date.now() in JavaScript returns milliseconds, so divide by 1000 to get seconds.
The Year 2038 problem: 32-bit signed integers overflow at 2,147,483,647 seconds — January 19, 2038. Modern 64-bit systems push this limit to the year 292 billion, making it irrelevant for new software, though legacy embedded systems may still be affected.
