A Complete Guide to German Numbers, Dates, and Times for Australians

Numbers, dates, and times in German have specific quirks that catch Australians off guard in everyday situations — at the supermarket checkout in Munich, reading a train timetable in Zurich, deciphering opening hours on a shop door in Vienna, or simply being told when to meet someone for coffee. German is logical once you understand the system, but there are enough differences from Australian English to cause real confusion if you are not prepared. This guide covers everything you need to confidently handle numbers, dates, and times in German-speaking countries.

German Numbers 1 to 20: The Foundation

The numbers one to twenty must simply be memorised. They form the building blocks of every larger number you will encounter, so getting these right early makes everything else much easier. Pay particular attention to sieben (7) and neun (9), which Australians commonly confuse when listening to fast speech.

Numbers 1 to 20 Reference Table

Mastering German numbers from one to twenty is your essential first step — these building blocks underpin everything from buying a coffee in Berlin to booking a train from Munich to Vienna. Unlike English, German numbers follow consistent patterns that, once recognised, make learning the rest of the number system much easier for Australian learners.

Key Patterns to Notice

Once you reach thirteen, most German numbers simply add -zehn (the equivalent of the English -teen) to the base number. There are a couple of exceptions worth noting:

\n
• sechzehn (16) — the final s is dropped from sechs
\n
• siebzehn (17) — the en is dropped from sieben
\n

Pronunciation Tips for Australians

\n
• zwei — sounds like tsvye; on phone calls, Germans sometimes say zwo to avoid confusion with drei
\n
• fünf — the umlaut ü is a sound between English oo and ee
\n
• zwölf — the ö umlaut trips up many beginners; practise it early
\n

Everyday Australian Context

Picture yourself ordering at a Bavarian beer hall: \"Ich möchte fünf Brezeln, bitte\" (I'd like five pretzels, please). Or confirming your hostel room number in Salzburg: \"Zimmer siebzehn\" (Room seventeen). Knowing these numbers cold will make your trip far smoother.

Pronunciation Tips for Australians

\n
• zwei — sounds roughly like \"tsvye\". In noisy environments such as train stations or markets, Germans sometimes say zwo instead to avoid confusion with drei.
\n
• fünf — the umlaut ü sounds like the \"u\" in the French word tu. Round your lips as if to say \"oo\" but say \"ee\" instead.
\n
• sechs — pronounced \"zeks\", not \"sex\" as many Australians instinctively read it.
\n
• sieben — three syllables: \"ZEE-ben\". Do not rush it or it sounds like siebzehn (17).

Tens, Compound Numbers, and the Reversed Word Order

This is where German first surprises Australian learners. For numbers between the tens — 21 through 99 — German places the units digit before the tens digit, connected by und (and). Think of it as the old English nursery rhyme \"four-and-twenty blackbirds\". It feels backward to modern Australian ears but it follows a completely consistent rule.

The Tens

Once you have mastered the numbers one to nineteen, the tens in German are relatively straightforward — and honestly, much more predictable than English. Most of them follow a clear pattern derived from the single-digit numbers you already know, so you will find them easier to remember than you might expect. Let's break them down properly.

The "-zig" Pattern

You will notice that most of the tens end in -zig, which is the German equivalent of the English "-ty" suffix. Think of "forty," "fifty," "sixty" — the same idea applies in German. Once you know this pattern, the numbers almost build themselves. The exceptions worth paying attention to are:

• dreißig (30) — This is the odd one out. Instead of "dreizig," German uses dreißig, with the special character ß (Eszett). This is one of those things that trips up a lot of Australian learners early on, especially when typing. On an Australian keyboard, you will need to either use a German keyboard layout, copy and paste the character, or use "ss" as a substitute in informal writing (dreiSSig → dreissig). In formal written German — like Goethe exam responses or official correspondence — always use the correct ß.
• sechzig (60) — Notice that the base word "sechs" loses its final "s" before adding "-zig." So it becomes sechzig, not "sechszig."
• siebzig (70) — Similarly, "sieben" drops its "-en" ending to become siebzig, not "siebenzig."

These small irregularities are worth drilling deliberately, because they are exactly the kind of thing that catches people out in listening comprehension — particularly when someone rattles off a phone number, a price, or a train platform number at speed.

Building Numbers in the Tens: The Reverse Rule

Here is where German numbers get genuinely interesting — and where most Australians have a moment of disbelief. When you combine a tens digit with a units digit (for example, 21, 47, or 83), German reverses the order compared to English and connects the two parts with the word und (and).

The formula is: [units digit] + und + [tens digit]

Yes, it really is written (and spoken) as one long word in German. This is normal. Germans are famous for compound words, and numbers are no exception.

Why This Matters for Australians in Real Life

If you are planning to visit Germany, Austria, or Switzerland — or thinking about studying or working there — you will encounter these numbers constantly in practical situations:

• Shopping and prices: A coffee in Munich might cost vierundvierzig Cent short change, or a supermarket item priced at siebenundzwanzig Euro neunzig (€27.90). Cashiers will not slow down for you.
• Public transport: Train platform numbers, bus route numbers, and departure times all rely on fast comprehension of these figures. Missing platform siebenundzwanzig because you heard "twenty-seven" backwards is a very real risk.
• Phone numbers and addresses: Germans often read two-digit numbers as pairs. A phone number segment like "47" becomes siebenundvierzig — and they expect you to write it down correctly.
• Goethe-Institut exams: In listening sections at A1 through B1 level, numbers appear constantly — in dates, times, prices, and quantities. Getting comfortable with the reverse structure is non-negotiable if you are preparing for certification.

A Quick Practice Tip for Australians

One of the most effective ways to lock in the tens is to practise with Australian contexts that feel real to you. Try saying your age in German, the current year, your suburb's postcode digits, or even the AFL score from last weekend. When numbers are attached to something personally meaningful, they stick far faster than abstract drills. Apps like Anki with a custom number deck, or simply narrating your daily routine aloud in German, can make a surprising difference within just a few weeks of consistent practice.

Compound Numbers: Units Before Tens

Compound numbers from 21 to 99 are written and spoken as a single word in German. Here are some practical examples:

\n
• 21 = einundzwanzig (one-and-twenty)
\n
• 37 = siebenunddreißig (seven-and-thirty)
\n
• 54 = vierundfünfzig (four-and-fifty)
\n
• 68 = achtundsechzig (eight-and-sixty)
\n
• 99 = neunundneunzig (nine-and-ninety)
\n

This reversed structure matters enormously when you are listening to prices, platform numbers, or addresses. If a cashier in a Berlin supermarket says \"siebenundzwanzig Euro\", you need to hear the seven first and understand the whole number is 27, not 72. Practise this actively before your trip.

Large Numbers and a Critical Warning for Australians

Large numbers follow logical patterns from the hundreds onward, but there is one significant false friend that can cause serious misunderstandings — particularly if you are dealing with property, finance, or business in Germany.

Hundreds and Thousands

Once you have mastered the numbers from one to ninety-nine, scaling up to hundreds, thousands, and beyond follows a very logical and consistent pattern. German is beautifully systematic here, and most Australians find this part of the language far less daunting than they expected. Whether you are negotiating a price at a Berlin flea market, checking a train fare from Munich to Salzburg, or filling out a visa form that asks for your annual salary, a solid grasp of large numbers in German is an absolute must.

The Core Hundreds and Thousands

Here is your essential reference list for the major building blocks:

• 100 = hundert or einhundert
• 200 = zweihundert
• 500 = fünfhundert
• 1,000 = (ein)tausend
• 10,000 = zehntausend
• 100,000 = hunderttausend
• 1,000,000 = eine Million
• 1,000,000,000 = eine Milliarde

Notice that hundert and tausend are written entirely in lowercase when they appear as part of a compound number. This trips up many English speakers, including Australians, who are used to capitalising "Hundred" or "Thousand" in formal written contexts. In German, capitalisation of these words only occurs when they are used as standalone nouns — for example, ein paar Hundert Menschen (a few hundred people).

How to Build Numbers in Between

The real power of German numbers comes from how cleanly they combine. You simply stack the components together without any connecting words like "and" (which English uses — think "one hundred and forty-two"). In German, you skip the "and" entirely:

• 101 = hunderteins
• 142 = hundertzweiundvierzig
• 256 = zweihundertsechsundfünfzig
• 999 = neunhundertneunundneunzig
• 1,450 = eintausendvierhundertfünfzig
• 25,000 = fünfundzwanzigtausend
• 375,000 = dreihundertfünfundsiebzigtausend

Yes, these can look intimidatingly long written out, but once you know the pattern, reading and saying them aloud becomes second nature with practice. The structure is always: thousands + hundreds + tens-and-units.

Millions and Billions — A Key Difference from English

This is where Australian learners need to pay close attention, because German and English part ways on terminology for very large numbers.

This is critical. The German word Billion does not mean one billion — it means one trillion. If you ever see a German news article discussing a country's national debt or GDP in Billionen, do not be alarmed thinking the numbers are off. They are using the long-scale numbering system traditional in continental Europe. Australia uses the short-scale system (same as the United States), where a billion is one thousand million. Germany uses the long-scale system, where a Milliarde is one thousand million and a Billion is one million million.

In everyday conversation and travel contexts, you are unlikely to need anything beyond Millionen and Milliarden, but understanding the distinction will save you from some genuinely confusing misunderstandings.

Punctuation: Commas and Decimal Points Are Swapped

Another common stumbling block for Australians is that Germany, Austria, and Switzerland use punctuation in numbers the opposite way to what we do at home.

• In Australia, we write: 1,250,000.50 (comma for thousands separator, full stop for decimals)
• In Germany, you write: 1.250.000,50 (full stop for thousands separator, comma for decimals)

This matters enormously in practical situations — when reading a rent price in a Munich apartment listing, checking the cost of a German car, or reviewing a salary offer from a Frankfurt employer. A price written as €1.250,00 means one thousand two hundred and fifty euros, not one euro and twenty-five cents.

Practical Australian Scenarios

Here are some real-world situations where you will use large German numbers as an Australian:

• Apartment hunting in Germany: Monthly rents in major cities are often quoted in the hundreds — achthundert Euro kalt (eight hundred euros excluding utilities) is a common phrase in rental listings.
• Goethe-Institut exams: Listening and reading comprehension tasks frequently include large numbers in contexts such as population statistics, historical dates, and prices.
• Train and flight bookings: Ticket prices, distances between cities (Munich to Vienna is roughly vierhundert Kilometer), and departure platform numbers all require confident number recognition.
• Working in Germany on a skilled visa: Your annual salary (Jahresgehalt) and any bank balance requirements for visa applications will be expressed using these larger number forms.
• Chatting with locals: Germans love discussing statistics — population figures, historical events, football transfer fees. Knowing your large numbers will keep you in the conversation.

A Quick Pronunciation Note

The word hundert is pronounced roughly like "HOON-dert" — the u is a short, rounded sound, not the flat Australian "u" as in "bun." Similarly, tausend sounds like "TOW-zent" (rhyming with the English word "how"). Practising these out loud, especially in long compound numbers, is the fastest way to build real fluency with German numerics.

Milliarde Is NOT a Billion

This is the most important large-number fact for Australians to learn. In German, eine Milliarde means one thousand million — what Australians call a billion. If you confuse these terms in a business meeting, a legal document, or even a casual conversation about economics, the consequences can range from embarrassing to genuinely costly. Take a moment to get this right before you move on.

The Core Confusion: Long Scale vs Short Scale

The difference comes down to two competing number systems used around the world. Australia, the United States, and most English-speaking countries use the short scale, where a billion equals one thousand million (1,000,000,000). Germany, Austria, Switzerland, and most of continental Europe traditionally use the long scale, where a Billion equals one million million (1,000,000,000,000) — what Australians would call a trillion.

Here is a quick comparison table to make this crystal clear:

Notice the pattern: German alternates between -ion and -iarde suffixes as you move up the scale, each step multiplying the previous number by one thousand. Australian English just keeps adding three zeroes each time with a new name.

Why This Matters for Australians in Real Life

You might think large numbers only come up in finance or politics, but they appear far more often than you expect. Here are some everyday situations where Australians living, working, or studying in Germany could run into trouble:

• Reading the news: A headline stating „Die Staatsschulden betragen zwei Billionen Euro" means Germany's debt is two trillion euros — not two billion. That is a very different story.
• Job contracts and salaries: Less common at the individual level, but company valuations and investment figures in job offer materials absolutely use these terms.
• University economics and business courses: If you are studying at a German university, your textbooks and lectures will use the long scale throughout.
• Talking about Australia: Australia's GDP is often quoted in the hundreds of billions of Australian dollars. In German, you would express this using Milliarden, not Billionen.
• Property and investment discussions: Sydney's property market alone is frequently valued in the hundreds of billions — again, Milliarden in German.

How to Remember the Difference

The simplest memory trick is this: Milliarde is the odd one out. In Australian English, there is no word that sounds like Milliarde. Every time you hear or see it, remind yourself it fills the gap between Million and Billion in the Australian system. It is the number with nine zeroes — 1,000,000,000.

Another approach is to count the syllables in the suffix:

• Million — two-syllable suffix, six zeroes
• Milliarde — three-syllable suffix, nine zeroes
• Billion — two-syllable suffix, twelve zeroes
• Billiarde — three-syllable suffix, fifteen zeroes

The pattern holds consistently across the entire German number system.

Pronunciation Tips for Large Numbers

Once you know the meaning, make sure you are saying these words correctly so native speakers understand you immediately:

• Milliarde — pronounced mil-ee-AR-deh (stress on the third syllable)
• Billion — pronounced BIL-yohn (stress on the first syllable, unlike the English word)
• Billiarde — pronounced bil-ee-AR-deh

A Quick Conversion Cheat Sheet

When converting between Australian English and German for large numbers, keep this rule in your back pocket:

• Australian billion → German Milliarde
• Australian trillion → German Billion
• Australian quadrillion → German Billiarde

Mastering this distinction separates beginner German speakers from those who can genuinely operate in professional and academic German-speaking environments. Get Milliarde locked in early, and the rest of the large-number vocabulary will fall into place naturally around it.
