Frequently Asked Questions

What is an IANA timezone?

Named timezone identifiers like America/New_York or Europe/Paris. Unlike UTC offsets (e.g. -05:00), they automatically account for DST changes.

Does it handle daylight saving time?

Yes. DST rules are built into your browser's Intl.DateTimeFormat implementation and update with each OS/browser update.

Why 'now' slightly different from my clock?

Your system clock may drift by a few seconds. The 'now' button uses your device time, so accuracy matches your OS clock sync.
