Frequently Asked Questions
Does the clock update automatically?
Yes. The time on each card refreshes every second using JavaScript's setInterval. There is no need to reload the page.
Does it handle Daylight Saving Time?
Yes. The tool uses the browser's built-in Intl.DateTimeFormat API with IANA timezone identifiers (e.g. America/New_York), which automatically accounts for DST transitions.
Why does a card appear dark?
Cards with a dark background indicate the local time in that city is between 20:00 (8 PM) and 06:00 (6 AM) — considered night-time hours.
