World clocks & live time
Analog & digital multi-city clocks
A wall of classic dials for the cities you care about, each with a crisp digital readout and a glow that tells day from night. Build your own set and watch them run.
How to use the analog & digital multi-city clocks
Pick your cities
Add the zones you want on the wall. Each gets its own dial with a sweeping second hand and a digital readout underneath.
Compare hand positions
Analog dials make offsets spatial. Two cities four hours apart show their hour hands a fixed angle apart, which is faster to read across six clocks than six sets of digits.
Check the day phase
Each clock is tinted by whether it is currently day, twilight or night there, so a dial reading 10 is never ambiguous between morning and evening.
Leave it running
The second hand runs on a CSS animation seeded once at load, so it glides smoothly and costs almost nothing — safe to leave on a spare monitor all day.
Analog and digital, and when each one wins
A digital readout is precise and a dial is comparative. When you need to know whether it is 14:05 or 14:06, digits win. When you need to take in six cities at once and judge which are in the same part of their day, the dial wins, because the eye reads angle far faster than it parses numerals.
This is why airport and newsroom walls have used rows of analog clocks for a century. The information they carry best is not the exact minute but the shape of the day — a wall where three hands point roughly up and three point roughly down tells you the state of your organisation in one glance.
The ambiguity in a twelve-hour dial is real: a hand at 10 could be morning or evening. Rather than force a 24-hour face, which most people read slowly, each clock here carries a day-phase tint computed from the city's real solar elevation. You get the readability of the familiar dial without the ambiguity.
Every clock is driven by the same tick and the same IANA zone database, so all the dials agree with each other and with the digital readouts, daylight saving included.
When you'd reach for it
Office wall display
The newsroom pattern — a row of city clocks on a spare screen so the whole floor can see the offices at once.
Streaming overlays
Show your audience's zones alongside your own during a live broadcast.
Teaching clock reading
The dial and the digits move together, which is exactly the pairing a learner needs.
Reception areas
A hotel or agency lobby showing the cities its guests and clients come from.
Trading desks
Session-relative time is easier to judge from hand position than from a column of numbers.
Home office
A calm second-screen clock for the two or three zones you actually work across.
Questions & answers
- Do the clocks update in real time?
- Yes. Each dial's hands and digital readout tick live, and the sweeping second hand runs continuously for a smooth, fine-watch feel.
- How many cities can I show?
- Up to twelve at once — enough for a proper world-clock wall while keeping every dial readable.
- What is the coloured glow around each dial?
- It reflects that city's current light: warm at golden hour, cool at twilight, and dim at night, so you can read day or night at a glance.
