Telling Time

German runs two clocks side by side. There is the official, 24-hour clock you hear at train stations, on the radio, and in any formal context — clean, unambiguous, built straight out of the cardinal numbers you already know. And there is the colloquial, 12-hour clock of everyday speech, which is mostly easy except for one feature that quietly sabotages English speakers: the word halb. In German, halb drei is 2:30, not 3:30. Get that one fact wrong and you will arrive an hour late. This page covers both systems, the halb/Viertel logic, the regional southern quarter-system, and how to ask for the time.

Asking for the Time

Two questions, both completely standard:

Entschuldigung, wie spät ist es?

Excuse me, what time is it? (literally 'how late is it?')

Wie viel Uhr ist es?

What time is it? (literally 'how many o'clock is it?')

To answer, German uses es ist + the time. The word for "o'clock" is Uhr (also the word for "clock" and "watch"), and it stays singular and uncapitalized-in-meaning but capitalized as a noun. Note the irregular "one o'clock": you say es ist ein Uhr (with ein, not eins), but standing alone the hour "one" is eins.

Es ist ein Uhr.

It's one o'clock.

Es ist eins.

It's one. (just the bare hour, e.g. answering 'when?')

The Official 24-Hour Clock

This is the system used for schedules, broadcasts, official announcements, business, and anything written. (formal) You simply read the hour, the word Uhr, then the minutes — exactly as the digits appear. No tricks at all.

Time	German	Literal
14:30	vierzehn Uhr dreißig	fourteen o'clock thirty
08:05	acht Uhr fünf	eight o'clock five
20:15	zwanzig Uhr fünfzehn	twenty o'clock fifteen
00:45	null Uhr fünfundvierzig	zero o'clock forty-five
23:59	dreiundzwanzig Uhr neunundfünfzig	twenty-three o'clock fifty-nine

Der Zug nach Hamburg fährt um vierzehn Uhr dreißig.

The train to Hamburg leaves at 2:30 p.m.

Die Sitzung beginnt um neun Uhr und endet um zwölf Uhr.

The meeting starts at nine and ends at twelve.

💡

The 24-hour clock is your safety net. If you are ever unsure how to phrase a colloquial time — or if being misunderstood would matter, like booking a doctor's appointment — fall back on vierzehn Uhr dreißig. It is always correct, always unambiguous, and no native speaker will think it odd in a scheduling context.

"um" for Clock Time

To say something happens at a certain time, use the preposition um. This is the one preposition you need for the clock; it takes no thinking about case here because Uhr is the fixed partner.

Wir treffen uns um acht Uhr vor dem Kino.

We're meeting at eight o'clock in front of the cinema.

Um wie viel Uhr fängt der Film an?

At what time does the film start?

Note that English "at half past" or "at quarter to" all collapse into the same um: um halb drei, um Viertel nach vier.

The Colloquial 12-Hour Clock — and the halb Trap

In casual speech (informal) Germans drop Uhr and use a 12-hour reckoning. The full hour is simple:

Es ist drei.

It's three (o'clock).

The minutes are where English speakers must rewire their intuition. German does not measure the half hour as "half past" the hour you have already reached. It measures it as half of the way toward the next hour. So:

halb drei = 2:30 — literally "half [toward] three," i.e. the third hour is half complete.
halb vier = 3:30
halb eins = 12:30

Clock	German	Logic
2:30	halb drei	halfway INTO the 3rd hour
3:30	halb vier	halfway INTO the 4th hour
7:30	halb acht	halfway INTO the 8th hour
12:30	halb eins	halfway INTO the 1st hour

Der Bus kommt um halb drei, also in zehn Minuten.

The bus comes at 2:30, so in ten minutes.

Ich gehe meistens um halb sieben ins Bett — ich bin ein Morgenmensch.

I usually go to bed at 6:30 — I'm a morning person.

💡

This is the single most dangerous time error for English speakers. halb drei is 2:30, the exact opposite of what English "half three" (3:30) trains you to expect. The German clock looks forward to the hour being completed; English looks backward to the hour just passed. Whenever you hear halb [X], subtract one from X and add :30. halb fünf = (5 − 1):30 = 4:30.

Quarters: Viertel nach and Viertel vor

The standard, nationwide way to handle quarter-hours uses nach (after/past) and vor (before/to), which behave exactly like their English equivalents — a relief after halb.

Es ist Viertel nach zwei.

It's quarter past two (2:15).

Wir sehen uns Viertel vor drei vor der Bibliothek.

We'll meet at quarter to three (2:45) in front of the library.

The same nach/vor logic handles other minute counts:

Es ist zehn nach acht.

It's ten past eight (8:10).

Es ist fünf vor zwölf.

It's five to twelve (11:55).

A common refinement: you can hang minutes off halb too. fünf vor halb drei = five minutes before 2:30 = 2:25; fünf nach halb drei = 2:35. This is fully idiomatic but optional — many speakers just say zwei Uhr fünfundzwanzig.

The Regional Southern/Eastern Quarter System

In southern Germany, Austria, Saxony, and parts of the east (regional: South/East), the quarters work like halb — counting toward the coming hour — and Viertel alone is enough:

Viertel drei = 2:15 (literally "a quarter [of the way to] three")
dreiviertel drei = 2:45 (literally "three-quarters [of the way to] three")

So dreiviertel vier is 3:45, and Viertel vier is 3:15. A speaker from Munich, Dresden, or Vienna will use these naturally; a speaker from Hamburg may not even understand them. This is a genuine north-south divide that has caused confusion between Germans themselves.

Komm doch um dreiviertel vier vorbei, dann ist der Kuchen fertig.

Come by at 3:45, the cake will be ready then. (regional: South/East)

💡

If you are learning standard German for nationwide use, master Viertel nach / Viertel vor as your active system — it is understood everywhere. Learn Viertel drei and dreiviertel vier only passively, so you recognise them when a Bavarian or Austrian says them. Mixing the two systems is how you end up at the bakery half an hour wrong.

a.m. / p.m. and Time of Day

German has no a.m./p.m. In the 12-hour system you disambiguate with a time-of-day word, used adverbially and lowercased: morgens (in the morning), vormittags (late morning), mittags (at midday), nachmittags (in the afternoon), abends (in the evening), nachts (at night).

Ich rufe dich um sechs an — abends, nicht morgens!

I'll call you at six — in the evening, not the morning!

Common Mistakes

❌ halb drei = 3:30

Incorrect — reading halb drei as English 'half three'.

✅ halb drei = 2:30

Correct — 'halfway toward three' counts forward, so it's 2:30.

The meaning-reversing halb error is in a class of its own; it does not just sound foreign, it sends you to the wrong place at the wrong time.

❌ Es ist eins Uhr.

Incorrect — the hour 'one' before Uhr must be ein, not eins.

✅ Es ist ein Uhr.

It's one o'clock.

❌ Wir treffen uns an acht Uhr.

Incorrect — clock time takes um, not an.

✅ Wir treffen uns um acht Uhr.

We're meeting at eight o'clock.

❌ vierzehn dreißig Uhr

Incorrect — Uhr goes between the hour and the minutes, not at the end.

✅ vierzehn Uhr dreißig

14:30 — the hour, then Uhr, then the minutes.

❌ Es ist Viertel nach halb drei.

Incorrect — German doesn't stack Viertel onto halb; this is not idiomatic.

✅ Es ist Viertel vor drei.

It's quarter to three (2:45).

Key Takeaways

Two clocks: the 24-hour clock (read straight: vierzehn Uhr dreißig) for anything formal, and the 12-hour colloquial clock for casual speech.
um is the preposition for clock time: um acht Uhr.
halb [X] = (X − 1):30 — halb drei is 2:30. This counts toward the next hour, the opposite of English.
Viertel nach (past) and Viertel vor (to) are the safe, nationwide quarter-hour words.
The southern/eastern Viertel drei (2:15) and dreiviertel vier (3:45) are regional — recognise them, but don't rely on them outside the South.
