You book a train. You know every word of the sentence. You still say am Dienstag when you meant Thursday, and suddenly you are in Hamburg a day early with no hotel.
Days and months are the first place beginner German pays you back. They are a closed list — seven, twelve, four — and they unlock calendars, appointments, birthdays, opening hours, and every wann? question you will ever be asked.
What you will get from this guide
- All seven days and twelve months with correct articles and pronunciation notes
- The four seasons, including the gendered surprises
- The German date format and ordinal numbers that go with it
- Real example sentences plus the prepositions that glue it all together
The German Days of the Week
Six of the seven are der — masculine. Only the first day of the week breaks the pattern. Pronounce them with a clear final -g as a soft k sound, not the English j.
One word deserves a flag: Sonnabend. In Berlin, Saxony, and much of northern Germany you will hear Sonnabend instead of Samstag. Both are correct, both appear on calendars, and nobody will look at you strangely for either.
How to Say "on Monday" in German
This trips up nearly every beginner, because English uses one word ("on") and German uses two, depending on the situation.
That lowercase montags with an -s is the phrase that makes you sound German rather than translated. Ich trinke montags keinen Kaffee is how a local says "I don't drink coffee on Mondays."
The Twelve German Months
All months are masculine: der Januar, der Februar, and so on. That single fact saves you dozens of adjective endings later.
Austria and southern Germany say Jänner and Feber where the north says Januar and Februar. If you are preparing for a Goethe-Zertifikat exam, use Januar and Februar — the standard written forms — but recognise the southern pair instantly.
How to Say "in March" or "in May"
German months almost never take a preposition alone. They take im.
Those bare Anfang, Mitte, and Ende constructions feel naked to English ears. They are perfectly normal German. Anfang Mai fahre ich nach Wien — "At the beginning of May I'm going to Vienna."
The Four Seasons and Their Genders
Here German stops being predictable. Two seasons are masculine and two are feminine, and there is no logic to rescue you.
For the seasons, use im: im Sommer, im Winter. But when you mean "in summer" as a general category, German also accepts im Sommer regardless — unlike English, where "in the summer" and "in summer" differ slightly. German does not care.

German Dates: The Format That Confuses Everyone
Here is the rule that saves you from booking the wrong flight. German writes dates as day.month.year — and the day comes first, always.
So the German Unity Day holiday 03.10. is October 3rd, not March 10th. Americans lose days of their lives to this.
Ordinal Numbers for Dates
German dates need ordinals, and the pattern is beautifully regular after the first few.
From 4 to 19, add -te. From 20 upward, add -ste. The two irregulars — dritte and siebte — are worth memorising early because they appear in the calendar every single month.
Knowing the words is not the same as hearing them

Five Mistakes to Stop Making
Saying "in Montag". German never uses in for days. Use am.
Forgetting that months are masculine. Der März ist kalt — not die or das.
Writing 03/10 to mean March 10. In German, that is 3 October. Write it out if there is any doubt.
Mixing up Samstag and Sonntag under pressure. Samstag = Saturday, Sonntag = Sunday. Say both aloud ten times when you learn them; the syllables are close and nerves blur them.
Pronouncing the -g in Tag as a hard English g. It softens toward a k. Tach in casual Berlin speech, Tak in careful speech.
Practice Plan That Actually Works
Recite the days in order every morning for two weeks, out loud. Then switch to random order — that is where real retrieval lives. Add one sentence per day using am plus the current day. By week three, am Donnerstag arrives without translation, and your calendar stops being a minefield.
Turn a word list into a conversation
A self-paced A1 course with an AI voice tutor takes days, months, and seasons straight into dialogue — appointments, birthdays, holiday plans. Vocabulary sticks when you use it in speaking practice with instant AI feedback.

Are German days of the week masculine? Yes, all seven take der, including der Samstag and der Sonntag. In everyday speech the article is usually dropped unless an adjective precedes it: am kalten Montag.
Why do Austrians say Jänner instead of Januar? Jänner is the older form, still standard in Austrian German and used in official documents. Both appear in Goethe-Institut materials as recognised variants.
How do I write a German date with the day first? Write 3. Oktober 2025 or numerically 03.10.2025. The dot after the number is required in German and marks it as an ordinal.
Is it "im Sommer" or "in den Sommer"? Use im Sommer for a season. In den Sommer appears only in movement phrases like Wir gehen in den Sommer hinein, which is literary and rare.
