What this tool does

Unix timestamps count seconds since January 1, 1970 UTC. Developers encounter them in APIs, databases, analytics exports, and server logs.

How to use it

  1. 1

    Choose Unix → Date or Date → Unix mode.

  2. 2

    Enter a timestamp or date string.

  3. 3

    Copy the converted result.

Common pitfalls

JavaScript uses milliseconds — divide by 1000 when converting from Date.now(). Python and most APIs use seconds.

Always confirm timezone when comparing timestamps — UTC vs local time causes off-by-hours bugs.

Tips

  • Use "current time" button for live debugging.
  • Store timestamps in UTC; convert to local only for display.
