About Unix Timestamps

What is Unix time? Unix time (also known as Epoch time) is a system for describing points in time. It's the number of seconds that have elapsed since January 1, 1970 (UTC).

Seconds vs Milliseconds: Most systems use seconds (10 digits), but JavaScript uses milliseconds (13 digits). This tool handles both automatically.

Use cases: Databases, APIs, scheduling, logging, date calculations, and time-based operations in programming.

What is Epoch Time?

Epoch time (also called Unix timestamp) is a system for representing points in time as a single number. It's the number of seconds (or milliseconds) that have elapsed since January 1, 1970, 00:00:00 UTC, also known as the Unix epoch.

Epoch timestamps are widely used in computer systems, databases, APIs, and programming because they're timezone-independent, easy to store and compare, and efficient for calculations. Converting between epoch timestamps and human-readable dates is essential for developers working with time-based data.

How to Convert Epoch Timestamps

  1. 1

    Enter Epoch Timestamp

    Enter your epoch timestamp (in seconds or milliseconds) in the epoch input field. The tool automatically detects the format and converts it.

  2. 2

    Or Enter a Date

    Enter a date in the date input field to convert it to epoch timestamp. The tool will show both seconds and milliseconds formats.

  3. 3

    View Results

    See the converted date in multiple formats: ISO, UTC, local time, date only, time only, and relative time. Choose the format you need.

  4. 4

    Use Current Time

    Click 'Use Current Time' to see the current date and time converted to epoch format. Useful for testing and quick reference.

Frequently Asked Questions

What is an epoch timestamp?

An epoch timestamp (also called Unix timestamp) is the number of seconds (or milliseconds) that have elapsed since January 1, 1970, 00:00:00 UTC. It's a standard way to represent time in computer systems, databases, and APIs.

Is this epoch converter free?

Yes, our epoch converter is 100% free to use. There are no limits on conversions, and no registration is required. All conversion happens in your browser.

What's the difference between seconds and milliseconds?

Epoch timestamps can be in seconds (10 digits, e.g., 1704067200) or milliseconds (13 digits, e.g., 1704067200000). Most Unix systems use seconds, while JavaScript uses milliseconds. Our tool automatically detects and handles both formats.

Can I convert dates to epoch timestamps?

Yes! Enter a date in the date input field, and the tool will convert it to epoch timestamp in both seconds and milliseconds. You can use various date formats, and the tool will parse them automatically.

What date formats are supported?

The tool displays dates in multiple formats: ISO 8601, UTC string, local string, date only, time only, and relative time (e.g., '2 hours ago'). This helps you see the date in the format you need.

Why do I need an epoch converter?

Epoch timestamps are commonly used in databases, APIs, logs, and programming. Converting between timestamps and human-readable dates is essential for debugging, data analysis, and understanding time-based data. This tool makes conversion quick and easy.
