Unix Timestamp Converter
Convert between Unix time and local date & time.
Unix time = seconds since 1970-01-01 00:00:00 UTC. Milliseconds are auto-detected (values above 10¹¹).
- Seconds or milliseconds?
- The calculator auto-detects: timestamps above 10¹¹ are treated as milliseconds, everything else as seconds.
- Is the result in my timezone?
- Local time is shown in your browser timezone; UTC and ISO 8601 values are also displayed.
- What is the Unix epoch?
- The Unix epoch is 1970-01-01 00:00:00 UTC. All Unix timestamps count seconds from that instant.
