Timestamp Converter

Convert Unix timestamps to human-readable dates and turn dates back into Unix time.

About this tool

Convert between Unix timestamps and readable dates for logging, APIs, analytics, and debugging.

Timestamp Converter is a debugging utility for logs, APIs, databases, and analytics tools that surface Unix time values. It removes the need to mentally parse seconds versus milliseconds every time a raw timestamp appears.

  • Supports seconds or milliseconds input.
  • Convert readable date values back into Unix time.
  • Useful for API debugging, event tracking, and database inspection.

How to use Timestamp Converter

Enter the Unix timestamp or the readable date, then use the paired conversion panels to move between formats. Check whether the input is in seconds or milliseconds first, because that is the most common source of incorrect results.

When this tool is useful

  • Convert Unix timestamps from logs or APIs into readable dates quickly.
  • Turn readable dates back into Unix time for testing, analytics, or database work.
  • Check whether a value is in seconds or milliseconds before debugging a broken time field.

Practical tips

  • Compare the magnitude first: millisecond timestamps are much longer than second-based values.
  • Use UTC-aware outputs when you are comparing logs across systems.
  • Copy both the readable date and raw timestamp when documenting a bug to avoid time-zone confusion.

Why people use this tool

People search for timestamp converters when they are already in the middle of a debugging task. The page works best when it gives a fast answer, clearly shows direction of conversion, and reduces unit confusion.

Frequently asked questions

Does the converter handle milliseconds?

Yes. The tool detects common 10-digit second values and 13-digit millisecond values.

Which timezone is used?

The readable preview includes both local browser time and UTC-based ISO output.

Does the converter handle millisecond-precision Unix timestamps?

Yes. If you paste a 13-digit timestamp the tool automatically detects it as milliseconds and converts it correctly, so you do not need to manually divide by 1,000 first.

Which time zone is used for the human-readable date output?

The output defaults to your browser's local time zone, but you can switch to UTC or any named IANA time zone to see the converted date in a different region.

How far back in time can the converter handle?

The tool supports the full range of signed 32-bit and 64-bit Unix timestamps, so you can convert dates from before 1970 (negative timestamps) as well as dates far into the future.
