I have a question.
Does ‘halb drei’ in German mean ‘halb vor drei’?

Yes, but it’s not expressed as ‘halb vor drei.’
2:30 is expressed as ‘halb drei’ in German.
It’s also expressed the same way in Dutch: ‘half drie.’
If you Google these expressions, you should see an image of the clock.

Thank you, Bruce.

Hi Yutaka, You can find some examples in this lesson: 03.07 Die Uhr II

Die previous and the next lesson in this course is about the time too.

Thank you, VeraI.
