Unix Timestamp Converter

Unix Timestamp Converter Free Online Tool

Our unix timestamp converter free online tool turns epoch numbers into dates and dates back into epoch numbers in one click.

Unix Timestamp to Readable Date Converter

A unix timestamp to readable date converter saves you from reading long strings of digits like 1700000000. Enter the number and the tool shows a clear date and time, such as 2023-11-14 22:13:20 UTC. It is handy for logs, API responses, database rows and spreadsheet exports. If you are also building a design for the same project, pick matching colors with our Color Palette Generator.

Convert Unix Epoch to Human Readable Time

To convert unix epoch to human readable time, you only need the number of seconds (or milliseconds) since January 1, 1970, 00:00:00 UTC. That starting point is called the Unix epoch. This tool reads the value, detects whether it is in seconds or milliseconds, and prints the time in a format people can understand.

Epoch Time to UTC Converter Online

Need a reliable epoch time to UTC converter online? UTC is the standard reference time, so it never changes with daylight saving or time zones. The result is shown in UTC first, followed by your browser's local time, which makes it easy to compare server logs with what you see on your own clock.

Convert Timestamp to Date and Time Free

You can convert timestamp to date and time free, with no limits, no account and no watermark. Use it as many times as you like for personal or commercial work. The reverse direction also works: choose a date and time, and the tool gives you the matching unix timestamp in seconds and milliseconds.

Unix Timestamp to Date Calculator Online

As a unix timestamp to date calculator online, the page updates the answer as soon as you change the input, so you do not need to press a generate button. It is useful for checking token expiry times, scheduled jobs, cache lifetimes and file modification dates. Working with unique record IDs as well? Create them with the UUID Generator.

How to Use the Unix Timestamp Converter

The tool takes only a few steps:

1. Paste your timestamp into the input box, or press Now to load the current time.
2. Check the detected unit: Seconds (10 digits) or Milliseconds (13 digits).
3. Read the result in UTC and in your Local time.
4. To go the other way, pick a date and time and read the generated timestamp.
5. Press Copy and paste the value into your code, spreadsheet or document.

Common Timestamp Examples

Here are a few values you can test with the converter:

0              = 1970-01-01 00:00:00 UTC
1700000000     = 2023-11-14 22:13:20 UTC
1700000000000  = same moment, in milliseconds

Tips for working with timestamps

• A 10-digit number is usually in seconds, and a 13-digit number is usually in milliseconds.
• Store and send timestamps in UTC, and convert to local time only when displaying them.
• Remember that JavaScript uses milliseconds, while many Unix tools and databases use seconds.
• Check the time zone before comparing two dates, because the same timestamp looks different in each zone.
