Learn Dutch: We eten om zes uur. - We eat at six o'clock.

In Dutch, the preposition used for specific times on the clock is always om. Whenever you want to say that something happens at a certain time, you must use om.

Doesn't uur literally mean 'hour'? Why is it translated as 'o'clock'?

Yes, uur literally translates to 'hour'. However, Dutch does not have a separate word for 'o'clock'. When stating a whole hour on the clock, you simply use the number followed by uur. So zes uur means six o'clock.

Since it is six o'clock, shouldn't uur be plural?

No, and this is a common rule in Dutch! When a number comes right before a unit of time or measurement (like hours, years, or meters), the unit usually stays in its singular form. That is why it is zes uur and not zes uren.

Can I put the time at the beginning of the sentence instead?

Yes, you can say Om zes uur eten we. Notice that if you move the time to the front, the verb (eten) and the subject (we) have to swap places. The verb usually has to be the second part of a Dutch sentence.
