About This Tool

Epoch Converter is a free online tool that converts Unix timestamps (also known as Epoch time) to human-readable dates and vice versa. Unix timestamps represent the number of seconds (or milliseconds) that have elapsed since January 1, 1970, 00:00:00 UTC. This format is the standard way computers and servers represent time, making it fundamental to programming, database management, and API development. Developers encounter Unix timestamps constantly when working with REST APIs, log file analysis, database queries, and authentication token expiration. Debugging time-related bugs often requires converting between timestamps and readable dates. Our converter supports both seconds and milliseconds formats, and can convert in both directions — from timestamp to date, or from date to timestamp. All processing happens in your browser — your data is never sent to any server.

How to Use

  1. Enter a Unix timestamp (in seconds or milliseconds) to convert it to a human-readable date.
  2. Or select a date and time to convert it to a Unix timestamp.
  3. The tool automatically detects whether your input is in seconds or milliseconds.
  4. Click 'Now' to get the current timestamp instantly.
  5. Use 'Copy' to copy the result to your clipboard.

Frequently Asked Questions

A Unix timestamp (also known as Epoch time) is the number of seconds or milliseconds that have elapsed since January 1, 1970, 00:00:00 UTC. It is a standardized way to represent time across different systems, programming languages, and databases.
The tool automatically detects your input format. If the number is greater than 10 digits, it is treated as milliseconds; otherwise, it is treated as seconds. You can also manually switch between seconds and milliseconds using the toggle option.
For 32-bit systems, the maximum representable timestamp is January 19, 2038 (known as the Year 2038 problem). For 64-bit systems, the maximum is much larger and can represent dates billions of years into the future, effectively eliminating any practical limit.
Yes. All processing happens entirely in your browser using client-side JavaScript. No data is sent to any server, stored anywhere, or shared with third parties. Your timestamp conversions remain completely private at all times.
