How To Use & FAQ

Q: Which unit should I use for Unix timestamps?

A: Most APIs use seconds, while many JavaScript systems use milliseconds.

Q: Why is my converted date wrong?

A: Usually the wrong unit was selected or the input date string is not timezone-aware.

Q: Why can Date -> Unix results differ across devices?

A: Non-ISO date strings may be interpreted by browser locale rules. Use ISO 8601 with timezone (for example, 2026-02-14T17:30:00+09:00) for consistent results.
