The German adverb vorüber is less common than the adverb vorbei—the German dictionary Duden rates vorüber 3 out of 6 for frequency of usage, compared to 4 out of 6 for vorbei—but they are used with a similar meaning in many contexts. In combination with sein ("to be"), vorüber and vorbei are usually translated as "past," "passed by," or "over."
In the following example, both of the adverbs are used, and the translator chose "over" for vorüber—a good choice considering the similarity to the preposition über ("over").
Hochzeitsnacht war vorüber. Hochzeitsnacht war vorbei .
The wedding night was over. The wedding night had passed.Play Caption
So, jetzt ist der Haxen fertig, die drei Stunden sind vorüber.
So now the knuckle is finished, the three hours have passed by.

The next two examples appear at first glance to use the adverb vorüber, but they actually use the separable German verb vorübergehen, often translated as "to go by" or "to pass by":
Mit jeder Welle kam ein Traum, Träume gehen vorüber
With every wave came a dream, dreams pass by [come and go].

This last example uses the verb vorüberziehen, which—oddly enough—also usually translates as "to go by" or "to pass by":
Im Schlepptau der flachen Plätten ziehen die Blumenkunstwerke vor der eindrucksvollen Bergkulisse vorüber.
In the tow line of the flat barges, the artworks made from flowers pass by in front of an impressive mountain panorama.

So while vorüber was at some point combined with gehen and ziehen to form the separable verbs vorübergehen and vorüberziehen, vorüber remains a fiercely independent adverb when combined with wehen. Depending upon the context, the following could also have been translated as "breezes by":
Ein Jahr weht vorüber...
A year flies past...
