Did you know?

Unix time is the number of seconds that have elapsed since Jan 1 1970 (UTC). It is widely used in systems to represent points in time independent of timezones.

Secure & Private

Like all our tools, timestamp conversion happens entirely in your browser. No data is sent to any server.

## The Developer's Time Machine Computers track time as a simple count of seconds since January 1, 1970 (the "Unix Epoch"). The **Unix Timestamp Converter** translates this machine-code into human-readable dates for debugging and logging. ### Features - **Bidirectional**: Convert Date ↔ Timestamp instantly. - **Precision Support**: We handle both **Seconds** (10-digit, standard Unix) and **Milliseconds** (13-digit, JavaScript standard). - **Timezone Aware**: See the result in both UTC (GMT+0) and your Local Time. - **Smart Detection**: Input a timestamp, and we guess if it’s seconds or milliseconds based on the length. ### Why use Timestamps? - **Unambiguous**: No confusion about "DD/MM/YYYY" vs "MM/DD/YYYY". - **Timezone Neutral**: A timestamp is the same instant everywhere on Earth. - **Sortable**: It's just a number, making chronological sorting easy for databases. ### Common Epochs - **0**: Jan 1, 1970 (The beginning). - **2147483647**: Jan 19, 2038 (The "Y2k38" problem for 32-bit systems).

Common Questions

QWhy is the date wrong by 3 years?

You likely mixed up seconds and milliseconds. If your timestamp has 13 digits, it's milliseconds. 10 digits is seconds.

QWhat is the Unix Epoch?

It is the arbitrary start date chosen by early Unix engineers (00:00:00 UTC on 1 January 1970). All Unix time counts from there.

QDoes this handle negative timestamps?

Yes. Negative numbers represent dates before 1970 (e.g., -1000 is Dec 31, 1969).

QIs it Y2038 safe?

Yes. Since JavaScript uses 64-bit floating point numbers for math, our tool handles dates well beyond the year 2038.
