Dates (de derde mei)

Building a Date

You already know the months and the ordinal numbers — Dutch combines them into dates with de + ordinal + month:

Today is the third of May.
Vandaag is het de derde mei.
Tomorrow is the fourth of May.
Morgen is het de vierde mei.

Events on a Date: op

An event happens op a date, just like on a day of the week:

The party is on the first of June.
Het feest is op de eerste juni.
The match is on the tenth of March.
De wedstrijd is op de tiende maart.
The appointment is on the sixth of September.
De afspraak is op de zesde september.

A date can also open the sentence. As with every fronted time expression, the verb then comes before the subject:

On the second of January I do not work.
Op de tweede januari werk ik niet.

Asking When

Wanneer works for dates exactly as you would expect:

When is the party?
Wanneer is het feest?

The Everyday Shortcut

In daily speech and writing, Dutch very often drops the ordinal and uses the plain number instead: tien april ("April 10") rather than de tiende april. Both are correct.

The concert is on April 10.
Het concert is op tien april.
