How to convert Unix timestamps

1

Timestamp to Date

Paste any Unix timestamp into the left pane. We'll instantly show you the local time, UTC, and relative time (e.g., "5 hours ago").

2

Date to Timestamp

Select any date and time using the browser's native picker on the right. We provide the epoch value in both seconds and milliseconds.

Live Epoch

The hero clock at the top shows the current Unix timestamp in real-time. Simply click it to copy the current epoch instantly.

The 1970 Zero Hour

The Unix timestamp (Epoch time) is the number of seconds that have elapsed since 00:00:00 UTC on January 1, 1970. It is the universal standard for storing time in databases and systems across the globe, independent of time zones.

Built for developer productivity

Bidirectional Precision

Whether you're starting with a number or a date, our tool handles the conversion with zero configuration needed. Seamlessly switch between seconds and milliseconds.

Privacy First

Your timestamps and dates are never sent to a server. Everything is calculated in your browser using local resources, ensuring your data is 100% private.

Relative Time Analysis

Instantly see how far in the past or future a timestamp is. We provide a human-friendly "time ago" string for every conversion.

DST Aware

Conversions automatically account for your local system's Daylight Saving Time settings, providing accurate local time based on your browser's locale.

Epoch FAQ

What is the "Year 2038 Problem"?
On January 19, 2038, Unix timestamps stored as 32-bit signed integers will overflow. Modern systems have mostly moved to 64-bit integers, which can store dates for billions of years into the future, effectively solving the problem.
Seconds vs Milliseconds?
Standard Unix timestamps are in seconds (10 digits). JavaScript and many modern APIs use milliseconds (13 digits). Our tool supports both formats and detects them automatically when possible.
