Wij werken in september.

Both wij and we mean we.

• we is the more common unstressed form in everyday Dutch.
• wij is the stressed form, and it can sound a bit more formal or emphatic.

So:

• Wij werken in september.
• We werken in september.

Both are correct. In many normal conversations, we is more likely.

With wij/we in the present tense, Dutch usually uses the same form as the infinitive.

For the verb werken (to work):

• ik werk = I work
• jij werkt = you work
• hij/zij werkt = he/she works
• wij werken = we work
• jullie werken = you all work
• zij werken = they work

So werken is the correct present-tense form with wij.

In Dutch, months are normally used with in when you mean in a certain month.

Examples:

• in september = in September
• in januari = in January
• in de zomer = in the summer

So in september is the normal way to say that something happens during September.

In Dutch, names of months are normally written with a lowercase letter, unlike in English.

So Dutch writes:

• september
• oktober
• maandag

Not:

• September
• Oktober
• Maandag

This is standard Dutch spelling.

Yes, in this basic sentence it does:

• Wij = subject
• werken = verb
• in september = time expression

So the order is:

subject + verb + time expression

That said, Dutch word order can change more easily than English. For example, you can also say:

In september werken wij.

That is also correct. Dutch often puts a time phrase first, but then the verb still stays in second position.

This is an important Dutch rule: in a main clause, the finite verb usually comes in second position.

So if you start with the subject:

• Wij werken in september.

the verb is second.

If you start with the time phrase:

• In september werken wij.

the verb is still second, and the subject moves after it.

This is often called the V2 rule (verb-second).

Yes, absolutely. That is probably the most natural everyday version.

• Wij werken in september. = correct, slightly more formal or emphatic
• We werken in september. = correct, very common in speech and informal writing

A learner should understand both.

Grammatically, it is present tense. But in Dutch, just like in English, the present tense can often be used for future situations when the time is clear.

Because the sentence says in september, it can refer to something happening in that future month.

So Dutch does not always need a separate future form such as zullen werken. Very often, the simple present is enough.

No. Normally, month names in Dutch are used without an article.

So you say:

• in september
• vanaf september = from September
• tot september = until September

You would not normally say in de september.

A simple approximate guide for English speakers is:

• wij ≈ vay or why, but with a Dutch w/v-like sound
• werken ≈ VER-kuh(n)
• in = short in
• september ≈ sep-TEM-bur

A few pronunciation notes:

• Dutch w is softer than English w and can sound a bit between English w and v.
• The r in werken can vary depending on accent.
• The e in the last syllable of werken is a weak uh sound.

No, not in a normal complete sentence like this. Dutch usually requires the subject pronoun to be stated.

So:

• Wij werken in september. = correct
• Werken in september. = not a normal full sentence by itself

Dutch is not like Spanish or Italian, where the subject can often be dropped.

Yes. In september is correct; op september is not.

Dutch usually uses:

• in with months, years, seasons
• op with days and dates

Examples:

• in september = in September
• in 2026 = in 2026
• op maandag = on Monday
• op 3 september = on September 3rd

So for a month by itself, use in.
