Timestamp Converter

What is Timestamp Converter?

The Unix Timestamp Converter on AiTechWorlds converts Unix epoch timestamps to human-readable dates and times, and converts dates back to Unix timestamps. Unix timestamps — the number of seconds (or milliseconds) since January 1, 1970 UTC — are the universal time representation used in programming: database records, API responses, JWT tokens, log files, and analytics events all use them. Reading a timestamp like '1717200000' requires conversion to know it means May 31, 2024. This tool handles both directions, supports second-precision and millisecond-precision timestamps, and shows the result in multiple formats (UTC, local time, ISO 8601). All conversion runs in your browser with no server call. AiTechWorlds built this tool for developers who regularly work with timestamps in APIs, databases, and log analysis.
