Unix timestamp basics

A Unix timestamp counts seconds from January 1, 1970 at 00:00:00 UTC. Some systems use milliseconds instead, so 1771177399 and 1771177399000 can represent the same moment at different precision.

Use this converter when moving between human-readable dates and machine-readable timestamps for logs, APIs, subtitles, datasets, automation, analytics, or debugging.

Time zone warning

A timestamp represents a moment in UTC, but a displayed date depends on the time zone used for formatting. If a converted time looks off by several hours, check whether the source expected local time, UTC, or an explicit offset.

Common mistake

Milliseconds are 1,000 times larger than seconds. If a date appears far in the future or near 1970, the input unit is probably wrong.
