🕐 Timestamp Converter
Convert Unix timestamps to readable dates and vice versa, supports seconds and milliseconds.
The Unix Timestamp Converter translates between Unix epoch timestamps and human-readable dates. Unix timestamps, the number of seconds since January 1, 1970 UTC, are used universally in programming, databases, log files, APIs and operating systems. They appear constantly in server logs, Windows Event logs, SQL databases and application debugging, and being able to convert them quickly is a regular need for IT professionals.
The tool auto-detects whether a timestamp is in seconds or milliseconds based on its length, a 13-digit timestamp is treated as milliseconds and automatically divided down to seconds before conversion. This handles the common source of confusion where JavaScript uses milliseconds while most Unix tools and databases use seconds.
The current time display at the top of the page shows the live Unix timestamp, UTC time and local time updating every second, useful as a quick reference when you need to know the current epoch time for a script or API call. The "Use Now" button in both converters populates the input with the current timestamp or date/time for quick calculations relative to the present moment.
