What is a UNIX Timestamp?

UNIX time (or epoch time) is the number of seconds that have elapsed since January 1, 1970 at 00:00:00 UTC. It’s used widely in computing systems for date and time representation. Timestamps may be in seconds (10 digits) or milliseconds (13 digits).

How to Use This Tool

1. Enter a UNIX Timestamp: Input a timestamp in seconds (e.g., 1652905200) or milliseconds (e.g., 1652905200123).

2. Choose a Timezone: Select from key timezones like UTC, Local, New York, Berlin, Tokyo, and more.

3. Convert to Date: Click “Convert to Date” to view the human-readable version based on your selected timezone.

4. Enter a Date & Time: Use the calendar and clock fields to input a specific date and time.

UNIX Timestamp to Date: FAQ

A UNIX timestamp is the number of seconds (or milliseconds) that have elapsed since January 1, 1970, at 00:00:00 UTC. It’s widely used in systems to represent time in a consistent, machine-readable format.

Timestamps in seconds are 10 digits long (e.g., 1652905200), while milliseconds are 13 digits (e.g., 1652905200123). Our tool supports both and adjusts automatically.

Yes. You can convert any valid UNIX timestamp—past or future—into a human-readable date, and vice versa.

The tool includes key global timezones like UTC, Local (auto-detected), New York, London, Berlin, Tokyo, and more. You can view and convert times across regions without guessing offsets.

The tool uses the browser's built-in time handling via JavaScript and the IANA timezone database. It’s accurate to the second and reflects daylight saving changes where applicable.

Absolutely. It’s ideal for parsing log files, debugging events, interpreting API timestamps, and any workflow where raw UNIX time needs context.

These are standard formats for displaying date/time:

ISO 8601: A modern, sortable format like 2025-07-01T12:34:56Z.
RFC 2822: A human-readable format like Tue, 01 Jul 2025 12:34:56 GMT.
Our tool shows both for convenience.
