Hviledagen planlegges etter langturen.

In Norwegian, nouns often take the definite article as a suffix instead of using a separate word like the.

So:

• hviledag = rest day
• hviledagen = the rest day

It is also written as one word because Norwegian commonly forms compound nouns this way:

• hvile = rest
• dag = day
• hviledag = rest day

So hviledagen literally means the rest-day.

Because Norwegian usually marks definiteness on the noun itself.

Compare:

• en hviledag = a rest day
• hviledagen = the rest day

So where English uses a separate article, Norwegian often adds an ending:

• -en for many masculine nouns
• -a or -en for feminine nouns depending on style
• -et for neuter nouns

Here, hviledag is masculine, so hviledagen means the rest day.

Planlegges is the present tense passive form of å planlegge = to plan.

So:

• planlegger = plans / is planning
• planlegges = is planned

This -s passive is very common in Norwegian, especially in formal, neutral, or general statements.

So:

• Hviledagen planlegges etter langturen. = The rest day is planned after the long run.

The sentence focuses on what happens to the rest day, not on who is doing the planning.

Yes. Hviledagen blir planlagt etter langturen is also possible.

Both can mean the rest day is planned after the long run, but there is a slight style difference:

• planlegges = shorter, often a bit more written/formal/neutral
• blir planlagt = also very common, sometimes feels a bit more explicit or conversational

In many contexts, they are interchangeable.

For the same reason: it is a compound noun with a definite ending.

• lang = long
• tur = trip, outing, hike, run, ride, etc. depending on context
• langtur = long trip / long outing / long run
• langturen = the long trip / the long run

Norwegian very often joins words together where English might use two words.

Tur is a flexible word in Norwegian. It can mean things like:

• trip
• outing
• walk
• hike
• run
• ride

So langtur depends a lot on context. If the topic is training, it may mean long run. If the topic is hiking, it may mean long hike. If the topic is general travel, it may mean long trip.

That is very normal in Norwegian: one word can cover several English possibilities.

Etter means after here.

So:

• etter langturen = after the long run / after the long trip

It introduces a time relationship: the planning happens after something else.

Etter can also be used in other ways in Norwegian, but in this sentence it is simply the preposition after.

This is standard Norwegian main-clause word order.

The basic structure is:

• subject: Hviledagen
• verb: planlegges
• adverbial/prepositional phrase: etter langturen

So it follows a very normal pattern:

• Subject + verb + other information

Norwegian main clauses usually place the finite verb in the second position. Since the subject comes first here, the verb naturally comes right after it.

Yes:

• Etter langturen planlegges hviledagen.

This is also correct. Norwegian often moves time expressions to the front for emphasis or flow.

Notice what happens: the verb still stays in second position, so you get:

• Etter langturen = first element
• planlegges = second position
• hviledagen = after the verb

That is a classic example of the Norwegian V2 rule.

Yes, hviledag is normally masculine in Bokmål:

• en hviledag
• hviledagen

That is why the definite singular form ends in -en.

If you wanted a rest day instead of the rest day, you could say:

• En hviledag planlegges etter langturen.

That means A rest day is planned after the long run.

Compare:

• hviledagen = the rest day
• en hviledag = a rest day

Yes. In Norwegian, the present passive often corresponds to English is + past participle.

So even though planlegges looks like one word, it functions like:

• is planned

That is why it is still considered a present-tense form.

In modern Norwegian pronunciation, hv is usually pronounced just like v.

So hviledagen is pronounced roughly as if it began with v rather than a strongly pronounced h.

This is helpful because spelling may suggest an English-like h, but that is usually not how it sounds in normal Norwegian speech.
