How it works
Enter a Unix timestamp in the input field. The converter automatically detects whether you're using seconds (10 digits) or milliseconds (13 digits) and displays the equivalent date and time.
Alternatively, enter a human-readable date to convert it to Unix timestamp format. The converter accepts various date formats including ISO 8601, US format, European format, and natural language dates.
Results display in multiple formats: Unix seconds, Unix milliseconds, ISO 8601, RFC 2822, and human-readable date with timezone. Copy any format with a single click.

What to Know Before Using
Unix epoch: Unix time counts seconds since January 1, 1970 00:00:00 UTC. This is the reference point for all Unix timestamps.
Format detection: 10-digit numbers are treated as seconds. 13-digit numbers as milliseconds. Dates are parsed automatically.
Timezone: Unix timestamps are UTC. Human-readable output shows your local timezone for convenience.
Negative timestamps: Dates before 1970 produce negative Unix timestamps. These are valid and handled correctly.
Year 2038: 32-bit Unix timestamps overflow in 2038. 64-bit systems and millisecond timestamps avoid this issue.
Common Questions
What is Unix timestamp?
Unix timestamp is the number of seconds since January 1, 1970 00:00:00 UTC. It's a universal way to represent points in time.
How do I convert timestamp to date?
Enter the Unix timestamp and read the human-readable date output. The converter handles the calculation automatically.
What's the difference between seconds and milliseconds?
Seconds (10 digits) is standard Unix time. Milliseconds (13 digits) is used by JavaScript. Milliseconds = seconds × 1000.
What timestamp is January 1, 2000?
January 1, 2000 00:00:00 UTC is timestamp 946684800 (seconds) or 946684800000 (milliseconds).
Can I convert future dates?
Yes. Unix timestamps work for any date from 1970 to 2038+ (depending on system). Future dates produce larger positive numbers.
How do I get current Unix time?
Use the current timestamp tool, or command line: date +%s (Unix/Linux/Mac). JavaScript: Math.floor(Date.now()/1000).
Why is my timestamp negative?
Negative timestamps represent dates before January 1, 1970. For example, December 31, 1969 is -86400 seconds.
