Overview
The German preposition am is a fundamental element for expressing specific temporal references, particularly for learners at the A2 CEFR level. It is a highly frequent contraction, crucial for clearly indicating when an event occurs. Understanding am allows you to specify days of the week, parts of the day, and exact dates, thereby anchoring your communication within a precise temporal framework.
This preposition is not merely a linguistic convenience; it reflects a core principle of German grammar regarding fixed points in time. Mastering its usage will significantly enhance the clarity and naturalness of your German expression. You will encounter am ubiquitously in daily conversations, formal scheduling, and written communications like emails or instant messages, making it indispensable for practical fluency.
How This Grammar Works
am is a contracted form, specifically merging the preposition an with the definite dative article dem. This grammatical fusion, known as a "Kontraktion" or "Schmelzwort," streamlines spoken and written German. The underlying preposition an is classified as a two-way preposition (Wechselpräposition).an refers to a point in time, it invariably signifies a fixed position on the timeline, rather than movement through time. Consequently, the dative case is always employed.der Montag, der Dienstag, etc.) and parts of the day (der Morgen, der Abend, etc.) are masculine. This grammatical gender dictates the use of the masculine dative definite article dem. Thus, an + dem Morgen contracts to am Morgen.das Wochenende, which also takes dem in the dative case, resulting in am Wochenende.an dem (e.g., an dem Montag) is highly uncommon and sounds exceptionally formal or antiquated in contemporary German. It would be comparable to an overly literal or legalistic phrasing in English. Native speakers almost exclusively opt for the contracted am in all informal and most formal contexts concerning time.an dem might appear is in very specific legal or poetic contexts, or when dem functions as a demonstrative pronoun (e.g., an dem Tag, der besonders wichtig war – "on that day, which was particularly important"), which is a distinct grammatical construction from the simple time expression. Your goal should always be to use am when referring to days, parts of days, or dates.Formation Pattern
am is straightforward, following a consistent pattern that simplifies its application. You combine the contracted preposition am directly with the noun or date specifying the time. Remember that in German, all nouns are capitalized. When indicating a specific date, the day number is followed by a period (.) which functions as an ordinal indicator (e.g., 12. meaning "twelfth").
am + [Time Noun/Date (Dative)].
am Montag | on Monday | an + der Montag |
am Freitag | on Friday | an + der Freitag |
am Morgen | in the morning | an + der Morgen |
am Nachmittag | in the afternoon | an + der Nachmittag|
am Abend | in the evening | an + der Abend |
am 1. Januar | on January 1st | an + der 1. Januar|
am 24. Dezember | on December 24th | an + der 24. Dezember|
am Wochenende | on the weekend | an + das Wochenende|
am consistently precedes the temporal noun, which implicitly adopts the dative case due to the an preposition. Ensure the noun's initial letter remains capitalized, as is standard for all German nouns. For dates, the ordinal number often clarifies the specific day within the month.
When To Use It
am to specify occurrences tied to distinct, singular periods generally encompassing a 24-hour cycle or a defined segment within it. This preposition acts as the German equivalent of "on" or "at" for these specific temporal contexts. Its application covers four primary categories:- Days of the Week:
amis mandatory for referring to any day from Monday through Sunday. This precisely situates an event on a particular day of the week, establishing a clear schedule. - Example:
Ich habe am Dienstag eine wichtige Präsentation.(I have an important presentation on Tuesday.) - Example:
Treffen wir uns am Samstag im Café?(Shall we meet at the café on Saturday?) - Example:
Ihr Geburtstag ist am Donnerstag.(Her birthday is on Thursday.)
- Parts of the Day: For most standard divisions of the day,
amis the correct choice. These includeder Morgen(morning),der Vormittag(late morning/forenoon),der Mittag(noon/midday),der Nachmittag(afternoon), andder Abend(evening). These terms are typically masculine, hence theamcontraction. - Example:
Wir frühstücken immer am Morgen.(We always have breakfast in the morning.) - Example:
Das Museum ist am Nachmittag geöffnet.(The museum is open in the afternoon.) - Example:
Er kommt am Abend zurück.(He's coming back in the evening.)
- Specific Dates: When you need to pinpoint an exact calendar date,
amis the appropriate preposition. This applies to birthdays, holidays, anniversaries, or any event scheduled for a particular day of a specific month. - Example:
Die Feier findet am 12. Juli statt.(The celebration takes place on July 12th.) - Example:
Ich bin am 3. Mai geboren.(I was born on May 3rd.) - Example:
Der Abgabetermin ist am 15. September.(The submission deadline is on September 15th.)
- The Weekend: Although
das Wochenendeis a neuter noun, it still usesambecausean+demapplies to neuter dative as well. This is a very common expression. - Example:
Was machst du am Wochenende?(What are you doing on the weekend?) - Example:
Am Wochenende fahren wir ans Meer.(On the weekend, we're driving to the sea.) - Example:
Ich entspanne mich gerne am Wochenende.(I like to relax on the weekend.)
am is its association with a singular, identifiable unit of time. If you can conceive of the time reference as a "point" on a calendar or within a daily cycle, am is likely the correct choice.When Not To Use It
am is versatile for daily and dated temporal references, there are specific contexts where its use is grammatically incorrect or semantically inappropriate. Employing am outside its designated scope is a common error among learners, leading to misunderstandings. Avoid am in the following situations:- Clock Times (
Uhrzeit): For precise clock times, German consistently uses the prepositionum(meaning "around" or "at" a specific hour).amrefers to larger temporal blocks like a day or a part of a day, not an exact hour. - Incorrect:
Ich treffe dich am 10 Uhr.✗ - Correct:
Ich treffe dich um 10 Uhr.✓ (I'll meet you at 10 o'clock.) - Incorrect:
Der Film beginnt am Mitternacht.✗ - Correct:
Der Film beginnt um Mitternacht.✓ (The film begins at midnight.)
- Months (
Monate): When referring to entire months,amis incorrect. The appropriate preposition isim, which is a contraction ofin+dem. This signifies being "in" a period of time longer than a day. - Incorrect:
Die Schule beginnt am September.✗ - Correct:
Die Schule beginnt im September.✓ (School starts in September.) - Incorrect:
Ihr Geburtstag ist am April.✗ - Correct:
Ihr Geburtstag ist im April.✓ (Her birthday is in April.)
- Seasons (
Jahreszeiten): Similar to months, seasons are also treated withim(in+dem). They represent extended periods thatamis not designed to specify. - Incorrect:
Wir fahren am Sommer in den Urlaub.✗ - Correct:
Wir fahren im Sommer in den Urlaub.✓ (We go on holiday in the summer.) - Incorrect:
Es regnet oft am Herbst.✗ - Correct:
Es regnet oft im Herbst.✓ (It often rains in autumn.)
- Years (
Jahre): For referring to specific years,amis never used. You typically useim(e.g.,im Jahr 2024) or simply state the year without a preposition if the context is clear (e.g.,2024 war ein gutes Jahr). - Incorrect:
Ich wurde am 1990 geboren.✗ - Correct:
Ich wurde 1990 geboren.✓ (I was born in 1990.) - Correct:
Das Gebäude wurde im Jahr 1900 gebaut.✓ (The building was built in the year 1900.)
- The Night (
die Nacht): This is a crucial exception to the "parts of the day" rule. UnlikeMorgen,Vormittag,Mittag,Nachmittag, andAbendwhich are masculine and useam,die Nachtis feminine. Consequently, it takes the prepositioninwith the feminine dative articleder, formingin der Nacht. This usage implies being "within" or "during" the night, rather than "at" a specific point. - Incorrect:
Ich lese gerne am Nacht.✗ - Correct:
Ich lese gerne in der Nacht.✓ (I like to read at night.) - Incorrect:
Die Sterne sind am Nacht sichtbar.✗ - Correct:
Die Sterne sind in der Nacht sichtbar.✓ (The stars are visible at night.)
Common Mistakes
am, often due to interference from their native language or an incomplete understanding of German case usage. Recognizing and consciously avoiding these errors will significantly refine your temporal expressions.- The "Midnight Mistake": The most persistent error is using
amfordie Nacht. As previously established,die Nachtis feminine, requiringin der Nacht. The other parts of the day are masculine and correctly useam. This singular exception often confuses learners expecting uniformity. - Incorrect:
Der Zug fährt am Nacht ab.✗ - Correct:
Der Zug fährt in der Nacht ab.✓ (The train departs at night.) - The error arises from treating
die Nachtidentically toder Morgen, overlooking its gender and the semantic nuance ofin.
- Confusing
amwithum: This mistake occurs when attempting to specify clock times witham. Remember,amdesignates a day or part of a day, whereasumprecisely marks an hour. - Incorrect:
Ich habe einen Termin am 15 Uhr.✗ - Correct:
Ich habe einen Termin um 15 Uhr.✓ (I have an appointment at 3 PM.) - This is a clarity issue; using
amwith a clock time sounds grammatically disjointed and confusing to a native speaker.
- Using
amfor Months or Seasons: Another frequent error is extendingamto longer periods like months or seasons. These contexts requireim(in+dem). - Incorrect:
Mein Geburtstag ist am Juli.✗ - Correct:
Mein Geburtstag ist im Juli.✓ (My birthday is in July.) - The distinction lies in the duration;
amfor single days/parts of days,imfor multi-day periods.
am Morgenvs.morgens: While both relate to the morning, they carry different implications.am Morgenrefers to a specific morning (e.g.,am Montagmorgen– on Monday morning, or "this morning" in context).morgens(with a lowercase 'm' and ending in '-s') is an adverb indicating habitual action, meaning "every morning."- Incorrect:
Ich trinke Kaffee am morgens.✗ - Correct:
Ich trinke Kaffee morgens.✓ (I drink coffee every morning.) - Correct:
Am Morgen war ich sehr müde.✓ (This morning I was very tired.) - This error shows a lack of distinction between a specific temporal reference and a recurring habit.
- Over-formal
an dem: Althoughan demis the uncontracted form, using it in casual or even standard formal conversation for simple time expressions is unnatural. It sounds stiff and academic. - Awkward:
Ich komme an dem Freitag. - Natural:
Ich komme am Freitag.(I'll come on Friday.) - The contraction
amis the overwhelmingly preferred and expected form in contemporary German.
- Ignoring Ordinal Numbers for Dates: When writing dates, omitting the period after the number (
12.) is an oversight. The period signifies the ordinal nature of the number (e.g.,der zwölfte– the twelfth). - Incorrect:
am 12 Mai✗ - Correct:
am 12. Mai✓ (on May 12th)
Common Collocations
am, can significantly improve the fluency and authenticity of your German.am Wochenende: This is perhaps the most frequent temporal collocation witham, meaning "on the weekend." It is universally used.- Example:
Wir fahren am Wochenende in die Berge.(We're going to the mountains on the weekend.)
am Feiertag: This phrase translates to "on the public holiday" or "on the bank holiday."der Feiertagis a masculine noun.- Example:
Geschäfte sind am Feiertag geschlossen.(Shops are closed on the public holiday.)
am liebsten/am besten/am schönsten(Superlatives): While distinct from the temporal usage,amis also an integral part of forming the superlative degree of adjectives and adverbs in German. It combines with an adjective/adverb, often ending in-stenor-testen.- Example:
Ich esse Pizza am liebsten.(I like to eat pizza the most / My favorite is pizza.) - Example:
Er singt am besten von allen.(He sings the best of all.) - This highlights
am's broader grammatical role beyond mere temporal indication, functioning as a marker for superlative constructions.
am Morgen/am Vormittag/am Mittag/am Nachmittag/am Abend: These are standard and frequent ways to refer to specific parts of a day.- Example:
Treffen wir uns am Vormittag?(Shall we meet in the late morning?)
am ... Tag: You will often seeampreceding a specific day modified by an adjective, likeam nächsten Tag(on the next day) oram selben Tag(on the same day).- Example:
Ich rufe dich am nächsten Tag an.(I'll call you the next day.)
Contrast With Similar Patterns

Im Jahr 2025 planen wir eine Reise.(In the year 2025, we are planning a trip.) - More specific (Month):
Die Reise wird im August stattfinden.(The trip will take place in August.) - Even more specific (Day):
Wir fliegen am 15. August ab.(We fly off on August 15th.) - Specific part of the day:
Unser Flug geht am Morgen sehr früh.(Our flight departs very early in the morning.) - Exact time:
Wir müssen um 5 Uhr am Flughafen sein.(We have to be at the airport at 5 o'clock.)
am functions as your precise marker for daily and sub-daily segments, distinguishing it clearly from broader periods (im) and exact points (um).Quick FAQ
am.- Is it
am Wochenendeoran dem Wochenende? - Always use
am Wochenende. Whilean dem Wochenendeis grammatically derived, it sounds extremely archaic and unnatural in modern German. The contractionamis universally preferred and expected.
- Why do we say
am Morgenbutmorgens? am Morgenrefers to a specific morning (e.g., "this morning" or "on Monday morning"). It pinpoints an event to a single instance of morning.morgens(lowercase 'm', with an '-s' ending) is an adverb indicating a habitual action, meaning "every morning" or "in the mornings." For instance,Ich lese am Morgen die Zeitung(I read the newspaper this morning / on a specific morning) vs.Ich lese morgens die Zeitung(I read the newspaper every morning).
- Can I use
amfor holidays like Christmas? - Yes, if you're referring to the specific day of the holiday. For example,
am ersten Weihnachtstag(on Christmas Day/December 25th) oram Ostersonntag(on Easter Sunday). However, if you are referring to the general holiday period, you would typically usezu, such aszu Weihnachten(at Christmas time) orzu Ostern(at Easter time).
- Is it
am Mittagorzu Mittag? am Mittagrefers to the time of midday, e.g.,Ich rufe dich am Mittag an.(I'll call you at midday.)zu Mittagis typically part of the fixed expressionzu Mittag essen, meaning "to have lunch." So,Wir essen zu Mittag um 12 Uhr.(We have lunch at 12 o'clock.) The choice depends on whether you're indicating a time point or the act of having lunch.
- How do I specify a day within a month, like the 10th of May?
- You use
amfollowed by the day number, a period, and then the month:am 10. Mai. The period after the number indicates that it's an ordinal number (the tenth). You can also write it out:am zehnten Mai.
