About Unix Timestamp
Convert between Unix timestamps (seconds or milliseconds) and human-readable dates in any timezone. Handy for log parsing, debugging cron jobs, and reading database timestamp columns.
Frequently asked questions
Seconds or milliseconds?
Unix timestamps are traditionally seconds since 1970. JavaScript and many APIs use milliseconds. The tool auto-detects from the number of digits.
Why is my timezone off by an hour twice a year?
Daylight saving. Unix timestamps are always UTC; the converter applies your selected timezone's DST rules when displaying.
