Frequently asked questions
How does the world clock show public holiday status?
Each city card uses that city’s IANA timezone and local calendar date, then checks it against the official holiday calendars on this site for the linked country. The live board refreshes so you see whether today is a public holiday there.
When does daylight saving time (DST) apply and how does it affect meetings?
DST rules differ by city: London shifts between GMT and BST, while Tokyo, Singapore and Hong Kong stay on fixed offsets year-round. When DST starts or ends, the gap to other hubs changes even if your local clock does not — compare live times here before scheduling.
How can I plan overlapping working hours across time zones?
Open two or more city pages (or compare cards on this index) to see each local time side by side. Pick windows where all cities show business-hour overlap, then confirm none of those dates are public holidays in any participant’s country.
Which major financial and business cities are supported?
This hub covers Tokyo (Japan), Singapore, Hong Kong, and London (United Kingdom) — four Asia–Pacific and European hubs with linked national holiday calendars and dedicated city world-clock pages.
Why check local holidays—not just time zones—before cross-border calls?
A city can show the “right” local time while offices are closed for a public holiday, bridge day, or regional observance. Pairing live clocks with holiday status avoids no-shows and last-minute reschedules.
