Wij bespreken de kernuren op de kantoordag.

Both are correct in Dutch. Wij is the fuller form, while we is the unstressed, more everyday form.

So this sentence could also be:

We bespreken de kernuren op de kantoordag.

Using wij can sound a bit more careful, formal, or emphatic.

In the present tense, the wij form of most Dutch verbs is the same as the infinitive.

For bespreken, the present tense is:

• ik bespreek
• jij bespreekt
• hij/zij bespreekt
• wij bespreken
• jullie bespreken
• zij bespreken

So here bespreken means we discuss, not to discuss.

Yes. This is standard Dutch main-clause word order.

The basic pattern is:

subject + finite verb + rest

So in this sentence:

• Wij = subject
• bespreken = finite verb
• de kernuren op de kantoordag = the rest of the sentence

Dutch is a verb-second language, and the finite verb is indeed in the second position here.

They are two different cases:

• de kernuren: kernuren is plural, and plural nouns always take de
• de kantoordag: kantoordag is a singular de-word

So even though both use de, the reason is not exactly the same.

De usually points to something definite, known, or understood from context. So de kantoordag suggests a specific office day, or the office day already being discussed.

If you said een kantoordag, that would sound more like an office day, one of many, or a non-specific one.

So the choice between de and een depends on context, not just grammar.

Kernuren is a compound noun, which is very common in Dutch.

It is built from:

• kern = core
• uren = hours

The singular would be kernuur, but in practice the plural kernuren is often what you see, because people usually talk about these hours as a block of time.

Dutch often combines nouns into one word like this.

Because Dutch usually writes compound nouns as a single word.

So:

• kantoor
  • dag = kantoordag

This is different from English, where learners may expect two words such as office day. In Dutch, one-word compounds are the norm.

A useful rule: if English has a noun + noun combination, Dutch often turns it into one compound word.

Here op is being used in a time-related sense, roughly like on in English.

Dutch often uses op with days, occasions, or scheduled moments. So op de kantoordag means something like on the office day.

Depending on the exact context, Dutch might also use:

• tijdens de kantoordag = during the office day
• op kantoor = at the office

Those are not identical, but they are related ideas. If the focus is time, op de kantoordag can work. If the focus is location, op kantoor would be more natural.

Yes. Dutch lets you move elements for emphasis, as long as the finite verb still stays in second position.

So you can also say:

Op de kantoordag bespreken wij de kernuren.

That is still correct. Notice that bespreken remains the second element in the sentence.

Yes, it is understandable and quite natural in workplace contexts, especially when talking about hybrid work or scheduled in-office days.

It often refers to a designated day when people are expected to be in the office. So it fits modern office language well.

In other contexts, speakers might choose a different expression, but grammatically and stylistically kantoordag is perfectly fine here.
