About Timestamp Converter
Understanding Unix Timestamps
A Unix timestamp is the number of seconds since January 1, 1970 (UTC). It's how most systems store
time internally — databases, APIs, log files, and JWT tokens all use timestamps. The problem is
that 1711108800 doesn't mean anything to a human at a glance.
What This Tool Does
- Convert a Unix timestamp (seconds or milliseconds) to a human-readable date and time
- Convert a date and time back to a Unix timestamp
- See the current time as a live-updating timestamp
Seconds vs. Milliseconds
Classic Unix timestamps are in seconds. JavaScript's Date.now() returns milliseconds
(13 digits instead of 10). This tool handles both — if your timestamp has 13 digits, it's treated
as milliseconds automatically. For time zone conversions, use the
Timezone Converter.
