da / når
Choosing Da or Når
Danish uses two different words for 'when': da and når. The choice depends on whether the event happened once in the past, or if it happens repeatedly/in the future.
How It Works
In English, the word 'when' is a jack-of-all-trades. In Danish, you must distinguish between time and frequency.
1. Using 'da' (The Past Anchor)
Use da when you are talking about a single, specific event or a defined period in the past that is now over. It acts as a historical anchor.
- Da jeg var barn... (When I was a child - you were only a child once).
- Da vi kom hjem, spiste vi. (When we got home [that specific time], we ate).
2. Using 'når' (The Rule of Habit and Future)
Use når for anything that hasn't happened yet, or for things that happen regularly. A good trick is to see if you can replace 'when' with 'whenever'.
- Future: Jeg ringer, når jeg er klar. (I will call when I am ready).
- Habitual Past: Når det regnede, blev vi inde. (Whenever it rained, we stayed inside).
3. Word Order
Both are subordinating conjunctions. This means if you start a sentence with a da or når clause, the main clause must follow the V2 rule (Verb-Subject order).
4. The Mnemonic
Danish learners often use the rhyme: 'Dengang da, hver gang når' (That time da, every time når).
Examples (5)
- Da jeg så filmen, græd jeg.
When I saw the movie, I cried.
Word by Word: When I saw movie-the, cried I.
Use 'da' because seeing this specific movie happened at one specific point in the past.
- Jeg bliver glad, når solen skinner.
I get happy when the sun shines.
Word by Word: I become happy, when sun-the shines.
Use 'når' because the sun shining is a repeated, general occurrence.
- Vi ses, når du kommer hjem.
See you when you get home.
Word by Word: We see-each-other, when you come home.
Use 'når' for future events that haven't happened yet.
- Når jeg besøgte min mormor, fik jeg altid kage.
Whenever I visited my grandma, I always got cake.
Word by Word: When I visited my grandma, got I always cake.
Even though this is in the past, we use 'når' because it was a repeated habit (indicated by 'altid').
- Da vi boede i Aarhus, havde vi en hund.
When we lived in Aarhus, we had a dog.
Word by Word: When we lived in Aarhus, had we a dog.
Use 'da' for a specific, finished period in the past.
Common Mistakes
Using 'når' for a single past event.
Når jeg blev født, var det koldt.Da jeg blev født, var det koldt.You are only born once. For unique past events, you must use 'da'.
Using 'da' for future events.
Jeg kommer, da jeg er færdig.Jeg kommer, når jeg er færdig.'Da' is strictly for the past. For future timing, always use 'når'.
Confusing 'da/når' with 'hvornår' in questions.
Da kommer du hjem?Hvornår kommer du hjem?'Da' and 'når' are conjunctions used to link clauses. To ask a question about time, you must use 'hvornår'.

'Hvis' (if) expresses a condition, while 'når' (when) expresses a certainty in time.
