How It Works
This tool converts Unix timestamps (seconds since January 1, 1970 UTC) to human-readable date formats and vice versa. Enter a Unix timestamp to see it converted to various date formats (ISO 8601, UTC, local time), or pick a date to get the Unix timestamp. The current timestamp is shown in real-time. You can also see relative time (e.g., '2 hours ago'). All conversions happen instantly in your browser using JavaScript's Date API. Perfect for debugging API responses, database queries, and log analysis.
