Have you ever found yourself in a conversation with a German speaker, grappling with how to express a simple date, or perhaps misunderstanding an appointment time? The seemingly straightforward task of stating days, months, and years in German can quickly become a linguistic labyrinth, fraught with specific grammatical rules, prepositions, and formatting conventions that differ significantly from English. But what if you could navigate these nuances with the confidence of a native speaker, effortlessly scheduling your next meeting or discussing historical events without a second thought? This comprehensive guide is designed to transform your understanding, taking you from hesitant learner to a confident communicator of all things temporal in German.

Mastering the Days of the Week (Die Tage der Woche)

Let’s begin with the building blocks: the days of the week. In German, all days are masculine nouns and are always capitalized. This is a fundamental rule to remember.

  • Montag (Monday)
  • Dienstag (Tuesday)
  • Mittwoch (Wednesday)
  • Donnerstag (Thursday)
  • Freitag (Friday)
  • Samstag (Saturday) – also commonly Sonnabend, especially in northern and eastern Germany
  • Sonntag (Sunday)

When referring to something happening on a specific day, you generally use the preposition “am” (a contraction of “an dem” – “on the”).

  • Ich habe am Montag einen Termin. (I have an appointment on Monday.)
  • Treffen wir uns am Samstag? (Shall we meet on Saturday?)

To express something happening every day, you can add “-s” to the end of the day:

  • Ich arbeite montags. (I work on Mondays/every Monday.)
  • Der Laden ist samstags geschlossen. (The shop is closed on Saturdays/every Saturday.)

Unraveling the Months of the Year (Die Monate des Jahres)

Just like days, all months in German are masculine nouns and must be capitalized.

  • Januar (January)
  • Februar (February)
  • März (March)
  • April (April)
  • Mai (May)
  • Juni (June)
  • Juli (July)
  • August (August)
  • September (September)
  • Oktober (October)
  • November (November)
  • Dezember (December)

To indicate something happening in a specific month, you use the preposition “im” (a contraction of “in dem” – “in the”).

  • Mein Geburtstag ist im Mai. (My birthday is in May.)
  • Wir fahren im August in den Urlaub. (We’re going on holiday in August.)

Understanding German Years (Die Jahre)

Expressing years in German is generally quite straightforward. For years up to 1999, you typically say the hundreds and then the tens/units, similar to English but often with “neunzehnhundert” (nineteen hundred) as a base.

  • 1999: neunzehnhundertneunundneunzig
  • 1871: achtzehnhunderteinundsiebzig

For years from 2000 onwards, it’s simpler, often just stating the full number:

  • 2000: zweitausend
  • 2023: zweitausenddreiundzwanzig
  • 2005: zweitausendfünf

When referring to something happening in a particular year, you use “im Jahr” or “im Jahre” (the latter is slightly more formal/older usage but still acceptable).

  • Die Mauer fiel im Jahr 1989. (The Wall fell in the year 1989.)
  • Im Jahre 2020 begann die Pandemie. (In the year 2020, the pandemic began.)

The Crucial Role of Ordinal Numbers (Ordnungszahlen)

Unlike English, where we say “January first,” in German, you typically use ordinal numbers (1st, 2nd, 3rd, etc.) when stating dates. These act like adjectives and must be declined. The base forms are:

  • 1st: erste
  • 2nd: zweite
  • 3rd: dritte
  • 7th: siebte (note the dropped ‘en’)
  • 8th: achte (note no double ‘t’)

For numbers 1-19, you generally add -te to the cardinal number.

  • 4th: vierte
  • 19th: neunzehnte

For numbers from 20 onwards, you generally add -ste.

  • 20th: zwanzigste
  • 21st: einundzwanzigste

When used in a date, the ordinal number typically takes the ending -ten because it follows a definite article (e.g., der) and is in the dative case (often implied by the preposition “am”).

  • Der erste Januar (The first of January)
  • Am ersten Januar (On the first of January)
  • Der fünfzehnte April (The fifteenth of April)
  • Am fünfzehnten April (On the fifteenth of April)

Asking and Stating the Date (Das Datum fragen und nennen)

Here are common ways to inquire about and state the date:

  • Asking:
    • Welches Datum haben wir heute? (What date is it today? / Which date do we have today?)
    • Der wievielte ist heute? (What’s the date today? / Which ‘how-many-eth’ is today?)
  • Stating:
    • Heute ist der erste Mai. (Today is the first of May.)
    • Heute ist der achtzehnte Juli. (Today is the eighteenth of July.)
    • Wir haben den zweiten Februar. (We have the second of February.)

Notice that when stating the date, we use “der” (nominative) for “Heute ist der…” and “den” (accusative) for “Wir haben den…”. The ordinal number also declines accordingly.

Prepositions are key to accurate date expressions. Here’s a summary:

Preposition Usage Example
am (an dem) On a specific day or date Am Montag treffen wir uns. (On Monday we meet.)
Am 24. Dezember ist Heiligabend. (On December 24th is Christmas Eve.)
im (in dem) In a specific month, season, or year Ich fahre im Sommer in den Urlaub. (I go on holiday in summer.)
Sie wurde im März geboren. (She was born in March.)
Im Jahr 2025 ziehe ich um. (In 2025 I’m moving.)
vom… bis zum… From… until… (for a period) Der Kurs geht vom 1. bis zum 15. August. (The course runs from August 1st to 15th.)
vor Before (takes dative) Vor dem 5. Mai muss ich das erledigen. (Before May 5th I have to finish that.)
nach After (takes dative) Nach dem 10. Juni haben wir frei. (After June 10th we have time off.)
seit Since (takes dative) Ich warte seit dem 20. Januar auf eine Antwort. (I’ve been waiting for an answer since January 20th.)

Writing Dates in German: Formats and Conventions (Schreibweisen des Datums)

German date formats typically follow the DD.MM.YYYY order. Here are the most common ways to write dates:

  1. Numerical (DD.MM.YYYY): This is the most common and standard way for official documents, forms, and general communication. Note the periods (full stops) after day and month, and no leading zeros for single-digit days/months are common, though leading zeros (01.03.2023) are also correct and often preferred for clarity.

    • 1.3.2023 (March 1st, 2023)
    • 15.11.2024 (November 15th, 2024)

  2. With Month Name (DD. Monat YYYY): For more formal or descriptive writing, the month name is often used.

    • 1. März 2023 (March 1st, 2023)
    • 15. November 2024 (November 15th, 2024)

  3. Including the Day of the Week (Wochentag, DD. Monat YYYY):

    • Mittwoch, 1. März 2023 (Wednesday, March 1st, 2023)

  4. Shortened Year (DD.MM.YY): While common in informal contexts, it can lead to ambiguity (e.g., 1.3.23 could be 1923 or 2023).

    • 1.3.23

  5. ISO 8601 Standard (YYYY-MM-DD): Increasingly used in technical, scientific, and international contexts to avoid ambiguity.

    • 2023-03-01

Crucially, remember that the day is always an ordinal number, even if written numerically. The period after the number (e.g., 1.) indicates its ordinal nature.

Practical Scenarios and Common Pitfalls (Praktische Szenarien und häufige Fehler)

Let’s look at a few common scenarios and how to avoid typical mistakes:

  • Birthdays: “Wann hast du Geburtstag?” (When is your birthday?) – “Ich habe am 10. Juli Geburtstag.” (My birthday is on July 10th.) Here, “am” is followed by the dative form of the ordinal number.

  • Appointments: “Der Termin ist am Freitag, den 20. April um 14 Uhr.” (The appointment is on Friday, April 20th at 2 PM.) Notice “den” before the date because “der 20. April” is in the accusative case, as if it’s the direct object of an implied verb like “haben” or “sein”.

  • Historical Events: “Die Berliner Mauer fiel am 9. November 1989.” (The Berlin Wall fell on November 9th, 1989.)

Common Pitfalls:

  • Forgetting Capitalization: Days and months are always capitalized!
  • Incorrect Prepositions: Using “in” instead of “am” or “im” can change the meaning or sound unnatural.
  • Missing Ordinal Endings: Not declining the ordinal number correctly (e.g., saying “der zwei April” instead of “der zweite April” or “am zweiten April”).
  • Confusing DD/MM/YYYY: Especially with numerical dates, remember the German standard is day-month-year.

By diligently practicing these rules and paying attention to the context, you’ll soon find yourself expressing dates in German with native-like fluency. Immerse yourself in German media, listen to how native speakers refer to dates, and don’t be afraid to make mistakes – they are part of the learning journey!
