German Time Preposition: 'At' (um)
um for pinpointing exact clock times, distinct from am (days) and im (months/seasons).
Grammar Rule in 30 Seconds
Use 'um' exclusively for clock times to say 'at' in German.
- Use 'um' for exact clock hours: 'um 8 Uhr'.
- Do not use 'um' for days or months: use 'am' or 'im'.
- Always place 'um' directly before the time expression.
Overview
Mastering German temporal prepositions is fundamental for precise communication, particularly when discussing schedules and appointments. While English often uses a single preposition, "at," for various temporal expressions (e.g., "at 8 o'clock," "at night," "at the weekend"), German distinguishes these contexts with greater specificity. For designating an exact point in clock time, German employs the preposition um.
This preposition is indispensable for conveying punctuality and clarity, ensuring your German interlocutors understand the precise moment an event occurs. Misusing um can lead to misunderstandings, from missed appointments to confusion about daily routines. Understanding um establishes a critical foundation for navigating time-related conversations in German.
How This Grammar Works
Um functions as a temporal preposition that consistently indicates a specific, fixed point on the clock. Grammatically, um is an accusative preposition. This means that any noun directly following um that can be declined will appear in the accusative case.um refers to clock time, it is typically followed by a cardinal number (the hour) and optionally the noun die Uhr. Since cardinal numbers do not inflect for case, and die Uhr in this construction acts more like a fixed unit of measurement rather than a standalone noun requiring article declension, the accusative case ending is not visibly manifested. Despite this lack of visible inflection, the underlying grammatical principle remains: um governs the accusative.um within the broader system of German prepositions, where prepositions are intrinsically linked to specific cases.um is to answer the question Um wie viel Uhr? (At what time?). It singles out a precise moment, much like an arrow pointing to a specific number on a clock face. For instance, if you say Der Film beginnt um acht Uhr, you are specifying the exact start time of the movie.für, während), general periods (in), and exact moments (um). Um fulfills the latter, marking a singular, non-extended temporal point.Formation Pattern
um for clock time follows a straightforward and consistent pattern. You combine the preposition um directly with the hour, optionally followed by die Uhr. The structure is:
um + [Stunde] + (Uhr)
[Stunde] represents the hour, which can be expressed in either the 12-hour format (informal) or the 24-hour format (formal/official). The inclusion of Uhr is standard in formal contexts and writing, but it is frequently omitted in casual spoken German when the context makes the meaning clear.
um acht Uhr | um acht Uhr | at eight o'clock | Usually clear from context |
um dreizehn Uhr | um eins | at one o'clock | Uhr often omitted informally |
um vierzehn Uhr dreißig| um halb drei | at half past two | halb refers to the next hour |
um sechzehn Uhr fünfzehn| um Viertel nach vier | at quarter past four | Viertel nach for xx:15 |
um siebzehn Uhr fünfundvierzig| um Viertel vor sechs | at quarter to six | Viertel vor for xx:45 |
um neunzehn Uhr | um sieben | at seven o'clock | 24-hour for clarity in evening |
um null Uhr | um Mitternacht | at midnight | Fixed expression for midnight |
um zwölf Uhr | um Mittag | at noon | Fixed expression for noon |
um sieben could mean 7 AM or 7 PM. To avoid ambiguity, particularly for evening times, the 24-hour system (um neunzehn Uhr) is preferred in formal settings and often used in casual speech for absolute clarity.
When To Use It
Um is exclusively used to specify a precise clock time or a singular point in the day that is universally recognized, such as noon or midnight. Its function is to pinpoint the exact moment an action or event is scheduled to occur, making it crucial for scheduling, appointments, and describing daily routines.- 1Exact Clock Times: This is the primary and most frequent use of
um. Whenever you refer to a specific hour and minute,umis the correct preposition.
Der Zug kommt um siebzehn Uhr dreiundvierzig an.(The train arrives at 5:43 PM.) This example highlights the precision required for travel schedules.Wir essen um achtzehn Uhr dreißig zu Abend.(We eat dinner at 6:30 PM.) This clarifies a fixed family routine.Der Online-Kurs beginnt um neunzehn Uhr fünfzehn.(The online course starts at 7:15 PM.) Essential for virtual meeting coordination.
- 1Appointments and Meetings: For any formal or informal gathering with a set start time,
umis mandatory.
Mein Arzttermin ist um zehn Uhr am Dienstag.(My doctor's appointment is at ten o'clock on Tuesday.) Here,umspecifies the hour, whileam(an dem) indicates the day.Kannst du mich um siebzehn Uhr anrufen?(Can you call me at 5 PM?) A direct request for a specific time.
- 1Public Transport and Event Schedules: Timetables for trains, buses, flights, as well as start times for concerts, movies, or sports events, invariably use
um.
Das Konzert fängt um zwanzig Uhr an.(The concert starts at 8 PM.) This is standard event information.Der letzte Bus fährt um null Uhr fünfunddreißig.(The last bus departs at 0:35 AM.) Crucial for late-night travel plans.
- 1Daily Routines and Habits: Describing when regular activities happen also calls for
um.
Ich stehe jeden Morgen um sechs Uhr dreißig auf.(I get up every morning at 6:30.) This details a personal routine.Die Geschäfte schließen um zwanzig Uhr.(The shops close at 8 PM.) This provides practical information about business hours.
- 1Fixed Points in the Day:
Umis also used withMittag(noon) andMitternacht(midnight), as these are precise, universally understood moments.
Lasst uns um Mittag zu Mittag essen.(Let's have lunch at noon.) This offers a clear meeting time.Der Countdown endet um Mitternacht.(The countdown ends at midnight.) This marks a definitive temporal boundary.
um is the only appropriate preposition in German. Its function is unambiguous and contributes significantly to German's reputation for precision.When Not To Use It
um is as crucial as knowing when to use it, as it helps prevent common errors and clarifies its specific domain within German temporal expressions. Um is strictly reserved for exact clock times and specific points like Mittag and Mitternacht. It is incorrect to use um for:- 1Days of the Week: For specific days, you must use
am(a contraction ofan dem).
- Incorrect:
Wir treffen uns um Samstag. - Correct:
Wir treffen uns am Samstag.(We meet on Saturday.)
- 1Parts of the Day (General): For general periods of the day like morning, afternoon, or evening,
amis also used (with the exception ofNacht).
- Incorrect:
Ich arbeite um Morgen. - Correct:
Ich arbeite am Morgen.(I work in the morning.) - Correct:
Ich arbeite am Nachmittag.(I work in the afternoon.) - Correct:
Ich arbeite am Abend.(I work in the evening.)
- 1The Night: The night (
Nacht) is an exception to theamrule for parts of the day. For "at night," usein der Nacht.
- Incorrect:
Ich schlafe um Nacht. - Correct:
Ich schlafe in der Nacht.(I sleep at night.)
- 1Dates: To refer to a specific date,
amis required.
- Incorrect:
Mein Geburtstag ist um der vierte März. - Correct:
Mein Geburtstag ist am vierten März.(My birthday is on March fourth.)
- 1Months, Seasons, and Years: For longer periods such as months, seasons, or years,
im(a contraction ofin dem) is the correct preposition.
- Incorrect:
Ich fahre um Juli in den Urlaub. - Correct:
Ich fahre im Juli in den Urlaub.(I go on holiday in July.) - Incorrect:
Es schneit um Winter. - Correct:
Es schneit im Winter.(It snows in winter.) - Incorrect:
Ich wurde um 2000 geboren. - Correct:
Ich wurde im Jahr 2000 geboren.(I was born in the year 2000.)
- 1Approximations or Durations:
Umsignifies an exact point. For approximations (e.g., "around 8 o'clock") or durations ("for two hours"), other prepositions or constructions are necessary. Usingumalone for an approximation is grammatically imprecise and potentially misleading.
- Incorrect (for approximation):
Ich komme um acht Uhr.(If you mean 'around 8'). - Correct (for approximation):
Ich komme gegen acht Uhr.(I'll arrive around eight o'clock.) - Correct (for duration):
Ich warte zwei Stunden.(I wait for two hours.) (No preposition for duration if accusative, orfür zwei Stunden)
Common Mistakes
um due to interference from English or confusion with other German prepositions. Recognizing these patterns and understanding the underlying reasons is key to avoiding them.- 1Confusing
umwitham: This is perhaps the most widespread error. Learners often mistakenly useam(for days and parts of the day) in place ofumfor clock times, or vice-versa. The fundamental distinction is thatam(an dem) governs a period of a day or a specific day/date, whileumgoverns an exact point in time.
- Example of Error:
✗ Ich komme am acht Uhr.(Incorrect –amis for days/dates, not clock time) - Correction:
✓ Ich komme um acht Uhr.(I'm coming at eight o'clock.) - Example of Error:
✗ Wir sehen uns um Montag.(Incorrect –umis for clock time, not days) - Correction:
✓ Wir sehen uns am Montag.(We'll see each other on Monday.)
- 1Omitting die
Uhrin formal contexts: While common in casual spoken German to sayum acht(at eight), omittingUhrin written communication, official announcements, or when utmost clarity is needed can lead to ambiguity or sound incomplete. Always includeUhrin formal settings.
- Ambiguous in writing:
✗ Das Meeting ist um neun.(Could be 9 AM or 9 PM, lacks formality). - Clear and formal:
✓ Das Meeting ist um neun Uhr.(The meeting is at nine o'clock.)
- 1Incorrect usage with general time expressions: Attempting to use
umwith phrases that denote a general period rather than a precise moment. This stems from not fully grasping the precision required byum.
- Error:
✗ Ich gehe um den Abend spazieren.(Incorrect –Abendis a period, not a specific point). - Correction:
✓ Ich gehe am Abend spazieren.(I go for a walk in the evening.)
- 1Misinterpreting the 24-hour clock: German speakers, especially in formal or public contexts, frequently use the 24-hour clock. Learners sometimes apply the 12-hour logic to a 24-hour context, leading to confusion.
- Potential misunderstanding: If you tell a German friend
Ich komme um acht Uhr.for an evening gathering, they might assume20:00 Uhr(8 PM). If you meant08:00 Uhr(8 AM), a misunderstanding occurs. - Clear usage: For evening times, specify with the 24-hour format:
Ich komme um zwanzig Uhr.(I'll come at 8 PM.) In casual conversation,um acht (am Abend)might also be used to clarify.
