What is Timestamp Converter?

Free online timestamp converter to convert Unix timestamps to human-readable dates and back again.

Convert epoch to a date, turn a date into a Unix timestamp, or read a millisecond timestamp from a log file. The tool supports both seconds and milliseconds precision, displays results in your local timezone and UTC, and shows a live-updating current Unix timestamp at the top. It is built for developers working with APIs, databases, JWT expiry fields, and any system that uses epoch time. Quickly understand when an event occurred or generate the exact timestamp you need. Everything runs in your browser, so nothing you enter leaves your device. No signup required.

How to Use Timestamp Converter

1View the current Unix timestamp updating in real time at the top
2Enter a Unix timestamp (seconds or milliseconds) to convert it to a human-readable date
3Or pick a date and time to convert it to a Unix timestamp
4Toggle between your local timezone and UTC for display

Frequently Asked Questions

A Unix timestamp (also called epoch time) is the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC. It is widely used in programming, databases, and APIs as a simple, timezone-independent way to represent a point in time.

A seconds-based timestamp is a 10-digit number (e.g., 1700000000). A milliseconds-based timestamp is a 13-digit number (e.g., 1700000000000) and provides more precision. JavaScript's Date.now() returns milliseconds, while many Unix systems use seconds.

The original 32-bit Unix timestamp will overflow on January 19, 2038 (the 'Year 2038 problem'). However, modern systems use 64-bit timestamps, which will last for over 292 billion years - effectively solving this issue.

Count the digits. A 10-digit number is seconds (for example 1700000000), and a 13-digit number is milliseconds (for example 1700000000000). The tool detects the length automatically, but you can also paste either format and check the resulting date looks right.

Yes. Pick a date and time in the date field and the tool returns the matching Unix timestamp in both seconds and milliseconds. Toggle between your local timezone and UTC so the generated timestamp matches the system you are working with.
