Das Standarduhrformat jedes Landes auf Telefonen und Betriebssystemen, basierend auf Unicode CLDR (der Datensatz, den jedes große Betriebssystem verwendet, um zu entscheiden, ob Ihr Sperrbildschirm 15:00 Uhr oder 15:00 Uhr anzeigt). Zwei Länder sind intern aufgeteilt: Kanada (Englisch ist standardmäßig 12 Stunden, Französisch ist 24 Stunden) und Syrien (Arabisch 12 Stunden, Kurdisch 24 Stunden).

Source: Unicode CLDR v48, supplemental/timeData.json. The reference iOS, Android, Windows, and macOS use to pick a default clock format per locale. Country shapes from Natural Earth.
Tools: Python, geopandas (Robinson projection), matplotlib, Claude Code for ideation and debugging.
UTC is the only true time
Always interesting when you can see the shadow of colonialism haunt a map like this
It would be interesting to see another division, what’s actually spoken about 14:30. 14:30, half three, half fifteen, half two or half fourteen?
This is just wrong. Argentina uses 24hs for literally everything but maybe casual speak. But no oficial document, appointment of any kind, official clock etc will use 12hs ever. It feels like Unicode did not care to cater to some regions
And certain apps, e.g. Discord, don’t follow the system settings, and only follow this. I always change Windows to 12 hour, but have to still put up with 24hr with Discord.
Well in Portugal we have a sort of mixed system. In writing it’s always a 24h system but colloquially we say „3 of the afternoon“, or „10 of the night“ (literal translations) as opposed to 15h or 22h. Might be due to analog clocks. Digital clocks are always in 24h mode.
i suppose this post is correct about Greece (?), but the vast majority of people/media/train stations, and basically anywhere you’d see the time digitally use the 24h format
Thank you! This is a nice way to find the data and a nice way to visualize it.
Canada is also split on whether on not we write MM/DD/YYYY or DD/MM/YYYY, and it’s goddamn annoying as hell.
Please tell me what 04/05/2026 is, reliably.
Canada is interesting that its split by language, when each country the language originates from is 24h anyway
would be interesting to see the population size for each group
Not sure the map’s correct. Japanese trains may be 24-hour clock, but Japanese uses a 12-hour clock when spoken.
Why is it that in any of these „world standard“ questions the US has the wrong format?
In Canada is officially 24h, but by USA influence, English people have a had time to count pass 12
Thid is not true. Chile uses both systems.
Weird, never saw 12 hours format used in Argentina.
I use 24h time on all my devices, but my brain translates it to 12h time automatically due to childhood in the USA. I will never say „1700 hours“, but I prefer seeing „17:00“ over „5:00 PM“. If someone asks me what time it is, though, I will automatically respond „5 PM“.
isn’t the uk 12 hours too?
Guy doesn’t get Thai time, which apart from being a little bit rubbery, is based on a 6 hour clock.
depends on your occupation. Australia uses 12hr time but i use 24hr time as a nurse in Australia so
It also is highly dependent on industry within Canada as well. So the default is generally 12h for English (Canada) locale, but work in a hospital for example and it’s 24h. Pretty much every country would be mixed if you also considered the industry.
