If you work with APIs, databases, log files, or backend code, you encounter Unix timestamps constantly — numbers like 1715000000 that represent a specific moment in time. Decoding them by hand is impossible. Our free Unix Timestamp Converter converts epoch timestamps to human-readable dates and dates back to timestamps instantly, with timezone support and multiple output formats.
What Is a Unix Timestamp?
A Unix timestamp (also called epoch time or POSIX time) is the number of seconds that have elapsed since 00:00:00 UTC on 1 January 1970 — a moment known as the Unix epoch. It is the most widely used time representation in computing because it is timezone-independent, compact (a single integer), easy to store, and trivially comparable. The timestamp 1715000000 represents May 6, 2024 at 19:13:20 UTC.
Seconds vs Milliseconds
Unix timestamps traditionally represent seconds, but many modern systems (especially JavaScript, Java, and mobile platforms) use milliseconds. A second-based timestamp has 10 digits (e.g., 1715000000), while a millisecond-based timestamp has 13 digits (e.g., 1715000000000). Our converter supports both — select the unit from the dropdown before converting.
How to Use the Timestamp Converter
- Timestamp to Date — Paste any Unix timestamp, select seconds or milliseconds, choose your timezone, and get the human-readable date in multiple formats instantly
- Date to Timestamp — Pick a date and time using the date picker and get both the second and millisecond Unix timestamps
- Live Clock — The tool shows the current Unix timestamp updating in real time, with a one-click copy button
Supported Output Formats
- Human-readable local format (e.g., May 6, 2024 at 07:13:20 PM)
- ISO 8601 format (e.g., 2024-05-06T19:13:20.000Z)
- UTC string format
