Unix Timestamp Converter

Convert Unix timestamps to UTC dates and ISO dates back to Unix timestamps.

Runs entirely in your browser — nothing uploaded to servers

Seconds since the Unix epoch

Unix timestamps represent seconds since January 1, 1970 UTC. This converter also accepts millisecond timestamps when the value is large enough.

Unix Timestamp Converter: complete online guide

Quick answer: translate epoch timestamps into human-readable dates or back again. Makes numeric time values much easier to interpret during debugging.

This free browser tool is built for developers, API testers, database users and technical students. It is designed to give you the useful result first, while the guide below explains the underlying idea, practical workflow and common mistakes. You can use FameOrbit from a modern phone, tablet or desktop browser, making the same workflow available to users and teams worldwide.

What is the unix timestamp converter?

Unix Timestamp Converter is a focused utility for a specific digital task. The important part is not only producing an output but understanding what that output represents and whether it matches the requirements of the next step. For professional, academic or production work, keep your source data, check units and constraints, and verify the final result after it reaches its destination.

How to use it

  1. Enter a Unix timestamp or date.
  2. Select the expected seconds or milliseconds format when needed.
  3. Convert the value.
  4. Use the result to inspect logs, API responses or data records.

Practical examples

Example

Convert a 10-digit epoch timestamp from an API response into a date.

Example

Convert a JavaScript date into an epoch value for a request or test fixture.

Best practices and common mistakes

Start with the actual requirement instead of choosing a number, format or setting just because it is a common default. Confirm the units used by your destination, avoid unnecessary conversions, and inspect the output before publishing, printing, importing or sharing it. When the task involves private information, review the privacy and security implications before submitting sensitive content to any online service.

Frequently asked questions

What is a Unix timestamp?

It is a numeric representation of time measured from the Unix epoch, commonly stored in seconds or milliseconds.

Why are some timestamps 13 digits?

Milliseconds use a larger number than seconds for the same instant, so JavaScript-style epoch values are commonly 13 digits.

Are timestamps affected by time zones?

Epoch time represents an instant; the displayed local date and time depends on the time zone used for presentation.
