I’d say Germany is about 50:50 verbally, but also depending on use. If using the 12h clock, one wouldn’t say “2:17”, rather round to “quarter past 2”. The other half of people would use “14:17”. But also if talking about timetables or other occurrences where the rounding would be detrimental, 24h will be u.sed.

Writing, I would say is about 90% 24h clock, because it’s just faster. Here, the divide would be between digital time (“14:17”) and military time (“1417”).

they’re used to it. my mother forbid me from setting up ad protection on her phone, because she’s used to them and didn’t want to learn how to switch it off when necessary (e.g. when it breaks a site she needs)
