Frequently Asked Questions
How many cities does the world clock cover?
The clock displays 66 cities in total: 16 major global hubs shown as individual cards at the top, and 50 additional cities listed in a scrollable table below. Together they cover every major time zone and business center across all inhabited continents.
What do the time-of-day icons mean?
Each city card shows a contextual icon based on the local hour. A sunrise icon (🌅) appears from 6:00 to 11:59, a sun (☀️) from 12:00 to 17:59, a city at dusk (🌆) from 18:00 to 21:59, and a moon (🌙) from 22:00 to 5:59. The icons give you an instant sense of whether it is business hours or the middle of the night without reading the exact time.
What do +1 day and -1 day mean?
+1 day means the city is on the next calendar date relative to your local date, and -1 day means it is on the previous one. This happens when a city is on the other side of the International Date Line from you or when the time difference pushes the date forward or back.
Does the clock handle Daylight Saving Time automatically?
Yes. The clock uses Luxon with full IANA timezone data, so DST transitions are applied automatically for every region that observes them. You do not need to adjust anything when clocks change in spring or autumn.
How often do the times update?
All city clocks refresh every second. You do not need to reload the page — the times advance continuously as long as the tab is open.
Can I use this to schedule an international meeting?
Yes. Find the cities where your participants are located, read their current local time and the time-of-day icon, and check whether the date is the same as yours. This tells you at a glance whether a time slot falls within business hours, in the evening, or overnight for each location.
What time format does the clock use?
All times are displayed in 24-hour (HH:mm:ss) format. This avoids AM/PM ambiguity and is the standard used in aviation, international business, and scientific contexts.
