Die toegangsure en ontruimingsdatum is op die toegangspas.

Because in Afrikaans, the present tense of to be is always is.

So:

• Die datum is... = The date is...
• Die datums is... = The dates are...
• Die toegangsure en ontruimingsdatum is... = The access hours and evacuation date are...

Unlike English, Afrikaans does not change is to are.

Die means the.

It appears twice because there are two separate noun phrases:

• die toegangsure en ontruimingsdatum = the access hours and evacuation date
• die toegangspas = the access pass

Afrikaans uses die for:

• singular nouns
• plural nouns

So die can mean both the and the before singular or plural nouns. There is no separate plural form of the article.

Because one die can cover both nouns when they are joined by en and treated as a single combined phrase.

So:

• die toegangsure en ontruimingsdatum = the access hours and evacuation date

You could think of it as:

• the [access hours and evacuation date]

This is normal in Afrikaans, just as in English you can say the manager and assistant without repeating the before both words.

En means and.

It joins:

• toegangsure = access hours
• ontruimingsdatum = evacuation date / move-out date / clearance date, depending on context

So the sentence is talking about two pieces of information together.

Because Afrikaans, like Dutch and German, very often forms compound nouns by writing them as a single word.

Here are the parts:

• toegangsure
  = toegang (access) + ure (hours)

• ontruimingsdatum
  = ontruiming (evacuation / clearing out / vacating) + datum (date)

• toegangspas
  = toegang (access) + pas (pass)

English often writes these as two words, but Afrikaans usually combines them into one compound noun.

That s is a linking sound/letter often used in Afrikaans compounds. It does not usually have a separate meaning by itself.

For example:

• toegang
  • ure → toegangsure
• ontruiming
  • datum → ontruimingsdatum
• toegang
  • pas → toegangspas

You should usually learn these compounds as whole words, because the linking s is common but not always fully predictable for learners.

Toegangsure literally means access hours.

It refers to the times during which entry is allowed.

Breakdown:

• toegang = access / entry
• ure = hours

So it is not talking about a duration like three hours. It means the allowed times for access.

Ontruimingsdatum is a compound noun meaning something like:

• evacuation date
• move-out date
• vacating date
• clearance date

The most natural English translation depends on context.

Breakdown:

• ontruiming = evacuation, emptying, clearing out, vacating
• datum = date

So this is the date on which a place must be vacated or cleared, or the official evacuation date.

Op usually means on.

In this sentence, op die toegangspas means on the access pass.

That is the natural way to say that information is printed or shown on a card, pass, document, or surface.

Examples:

• Dit is op die kaart. = It is on the map.
• Jou naam is op die lys. = Your name is on the list.

Yes. It follows a very common basic pattern:

Subject + verb + prepositional phrase

So:

• Die toegangsure en ontruimingsdatum = subject
• is = verb
• op die toegangspas = prepositional phrase

That is very similar to English:

• The access hours and evacuation date are on the access pass.

It is singular here: ontruimingsdatum = evacuation date / move-out date.

If it were plural, it would usually be datums.

So:

• datum = date
• datums = dates

In this sentence, there is one date but possibly multiple access hours or access times.

It could look like this:

Die toegangsure en ontruimingsdatums is op die toegangspas.

That would mean: The access hours and evacuation dates are on the access pass.

Notice that the verb is still is, because Afrikaans does not change it to are in the present tense.
