How to Use

Enter a Unix timestamp (e.g., 1700000000) and click Convert to Date to see the corresponding date.
Click Now to load the current Unix timestamp and its date breakdown.
Enter a date string (e.g., 2024-01-15T12:00:00Z) and click Convert to Timestamp to get the Unix timestamp.

How It Works

A Unix timestamp (also called Epoch time) is the number of seconds that have elapsed since January 1, 1970 00:00:00 UTC. It is widely used in programming, databases, and APIs to represent points in time in a timezone-independent way.

This converter supports both directions: timestamp to human-readable date and date string to timestamp. The output includes UTC, local time, ISO 8601, and relative time for convenience.

Frequently Asked Questions

A Unix timestamp is the number of seconds elapsed since the Unix epoch (January 1, 1970 00:00:00 UTC). It provides a simple, timezone-independent way to represent a point in time.

This tool uses seconds, which is the traditional Unix timestamp format. JavaScript's Date.now() returns milliseconds, so divide by 1000 to get the seconds-based timestamp.

The tool accepts any date string that JavaScript's Date constructor can parse, including ISO 8601 (e.g., 2024-01-15T12:00:00Z), RFC 2822, and common date formats.
