Quick answers to common questions
A Unix timestamp counts seconds (or milliseconds, microseconds, or nanoseconds) since 00:00:00 UTC on 1 January 1970 — the Unix epoch. It is timezone-independent and widely used in APIs, logs, and databases.
Unix timestamps are usually in seconds (10 digits). JavaScript uses milliseconds (13 digits). High-precision systems may use microseconds or nanoseconds — pick the input unit or use auto-detect.
Systems storing Unix time as a 32-bit signed integer will overflow on January 19, 2038 at 03:14:07 UTC. Modern 64-bit systems are not affected, but legacy embedded systems may be.
Yes. All conversion runs in your browser with the native Date object. No network requests are made.
ISO 8601 is a standard datetime format like 2024-05-20T14:30:00.000Z. It is common in JSON APIs and configuration files.
