Timestamp Converter

This free online timestamp converter helps developers work with Unix timestamps and dates. Unix timestamps represent the number of seconds (or milliseconds) that have elapsed since January 1, 1970 00:00:00 UTC (the Unix epoch), and are commonly used in programming, databases, and APIs.

The tool provides three essential features: view the current time in multiple formats with live updates, convert Unix timestamps to human-readable dates with timezone support, and convert dates back to Unix timestamps. The timestamp converter automatically detects whether your input is in seconds or milliseconds, and displays relative time (like "2 hours ago" or "in 3 days") for better context.

Perfect for debugging API responses, testing timestamp-based logic, converting between different date formats, or simply understanding what a timestamp represents. All conversions happen entirely in your browser using native JavaScript Date APIs and the Intl.DateTimeFormat API for timezone-aware formatting. No data is sent to any server.
