Timestamp Converter

Convert Unix timestamps to human-readable dates and vice versa. Supports both seconds (10-digit) and milliseconds (13-digit) epoch timestamps. Instantly converts to UTC and local time. Shows relative time ("3 hours ago") and lets you copy results for use in code.

How to Use Timestamp Converter

1
Paste or type a Unix timestamp (seconds or milliseconds) in the top field — the tool auto-detects whether it is 10-digit (seconds) or 13-digit (milliseconds).
2
The tool instantly shows the date in UTC, your local timezone, and ISO 8601 format.
3
Or pick a date and time using the date picker to get the corresponding Unix timestamp.
4
Toggle between seconds and milliseconds output with one click.
5
Copy the result to use in your code, database query, or API request.

Frequently Asked Questions

What is a Unix timestamp?▾

A Unix timestamp (also called epoch time) is the number of seconds elapsed since January 1, 1970, 00:00:00 UTC — the "Unix epoch". It is a timezone-independent way to represent any moment in time, widely used in databases, APIs, and log files.

Why does my timestamp have 13 digits instead of 10?▾

A 13-digit timestamp is in milliseconds (common in JavaScript: Date.now()). Divide by 1000 to get seconds. Our converter auto-detects the precision: timestamps under 10^12 are treated as seconds, those 10^12 and above as milliseconds.

How do I get the current Unix timestamp?▾

Click "Now" to get the current timestamp. In code: JavaScript: Math.floor(Date.now() / 1000), Python: int(time.time()), SQL: UNIX_TIMESTAMP() (MySQL) or EXTRACT(EPOCH FROM NOW()) (PostgreSQL).

What is the year 2038 problem?▾

32-bit systems store Unix timestamps as signed 32-bit integers, which overflow on January 19, 2038 at 03:14:07 UTC. Modern 64-bit systems are not affected and can represent dates billions of years into the future.

What is the difference between Unix time and ISO 8601?▾

Unix time is a single integer (seconds since 1970), timezone-independent and machine-friendly. ISO 8601 (e.g. 2024-03-15T14:30:00Z) is a human-readable string format. Both represent the same moment — use Unix time for calculations and storage, ISO 8601 for display and APIs.
