Convert Unix Timestamps to Readable Dates

Unix timestamps are useful for storing dates in applications, APIs and databases, but they are not easy to read at a glance. The DevToolbox Timestamp Converter turns an epoch value into a clear date and time.

Enter a Unix timestamp to view:

  • The corresponding date and time in GMT

  • The date and time in your local time zone

  • A relative value such as “3 hours ago” or “in 2 days”

The result updates as you change the timestamp.

How to Convert a Timestamp to a Date

  1. Enter a Unix timestamp in the “Unix Timestamp” field.

  2. The tool automatically identifies whether the value is in seconds or milliseconds.

  3. Review the converted date in GMT.

  4. Check the same date in your local time zone.

  5. View the relative time to understand how far the date is from the present.

Click “Now” to insert the current Unix timestamp.

Convert a Date to a Unix Timestamp

The converter also works in the opposite direction. Enter a year, month, day, hour, minute and second to generate the corresponding epoch timestamp.

You can interpret the entered date using:

  • UTC/GMT Time

  • Local Time

The generated result is provided as a Unix timestamp in seconds. Use the “Copy” button to copy it to your clipboard.

Current Unix Timestamp

The current Unix timestamp appears at the top of the tool and updates every second. The corresponding GMT date and time are displayed below it.

Use the “Pause” button when you need to stop the live counter and keep a particular value visible. You can resume the counter when you want to see the current time again.

Seconds and Milliseconds Support

Unix timestamps are commonly stored in either seconds or milliseconds. The converter automatically detects the likely format based on the length of the entered value.

A typical timestamp in seconds looks like:

1787656365

The same time in milliseconds looks like:

1787656365000

You do not need to select the format manually before converting the value.

GMT and Local Time Results

The same Unix timestamp represents one exact moment, but its displayed date and time can differ between time zones.

The GMT result shows the time using Greenwich Mean Time. The local result uses the time-zone settings detected by your browser and device.

Viewing both results is helpful when checking API responses, server logs or scheduled events created in a different time zone.

Relative Time Display

Along with the exact date, the converter provides a relative description of the timestamp. Depending on the difference from the current time, the result may be shown in minutes, hours, days, months or years.

Examples include:

  • This minute

  • 3 hours ago

  • In 2 days

  • Last month

  • Next year

This makes it easier to understand a timestamp without manually comparing it with the current date.

What Is a Unix Timestamp?

A Unix timestamp is the number of seconds that have passed since 1 January 1970 at 00:00:00 UTC. This starting point is known as the Unix Epoch.

For example:

0 represents 1 January 1970 at 00:00:00 UTC.

Unix timestamps are widely used because they store a date and time as a single numeric value. The value is independent of a displayed date format, although it must still be converted into a time zone when shown to a user.

Where Are Unix Timestamps Used?

Unix timestamps commonly appear in:

  • API requests and responses

  • Application databases

  • Server and error logs

  • Authentication tokens

  • Scheduled jobs

  • Analytics events

  • Cache expiration values

  • Content publication dates

  • Messaging systems

  • File and record metadata

The converter helps developers read these values and create timestamps for testing without writing a separate script.

Frequently Asked Questions

The Unix Epoch is 1 January 1970 at 00:00:00 UTC. Unix timestamps measure elapsed time from this starting point.

Yes. Enter a Unix timestamp in seconds and the tool will convert it into a readable date and time.

Yes. The converter automatically detects longer millisecond timestamps and processes them accordingly.

The converter checks the length of the entered number. Values containing 11 digits or fewer are treated as seconds, while longer values are treated as milliseconds.

Yes. Every timestamp-to-date conversion includes a GMT result.

Yes. The local-time result uses the time zone configured in your browser and device.

Yes. Enter the year, month, day, hour, minute and second to generate an epoch timestamp in seconds.

Yes. When converting a date to a timestamp, select either “UTC/GMT Time” or “Local Time.”

Yes. The current Unix timestamp updates once per second.

Yes. Click “Pause” to stop the current timestamp display from updating. Use the same control to resume it.

The “Now” button enters the current Unix timestamp into the timestamp-to-date field.

It describes the timestamp in relation to the current time, such as “3 hours ago” or “in 2 days.”

Yes. Use the “Copy” button beside the date-to-timestamp result.

No. A Unix timestamp identifies a particular moment in time. The time zone is applied only when that moment is displayed as a readable date and time.
