About this tool
Convert Unix timestamps in seconds, milliseconds or microseconds to ISO 8601, local time and relative time, or turn any date string back into a timestamp.
How to use it
- Paste a Unix timestamp in seconds, milliseconds or microseconds, or any date string.

Questions
- What is a Unix timestamp?
- The number of seconds since 1 January 1970 00:00:00 UTC, known as the Unix epoch. It is the same everywhere in the world, which makes it ideal for storing moments in time.
- Seconds or milliseconds?
- A current timestamp in seconds has 10 digits, in milliseconds 13. Unix tools and most APIs use seconds; JavaScript’s Date.now() returns milliseconds.
- What is the year 2038 problem?
- Systems that store timestamps as signed 32-bit integers overflow on 19 January 2038. Modern systems use 64-bit values and are not affected.
