"18"
To be contrary I would say that the answer is bit more complex than that.
The question is ambiguous as a "math, algebra, arithmetic" question; answers could be:
As an English usage question the answer is indeed generally agreed upon as being 18.
A dozen is twelve; a half dozen is therefore six.
One dozen = 12 so half a dozen = 12/2 = 6. So simple!
One dozen of roses for $52 is better value than half a dozen roses for $30.
Two and a half dozen is equal to 30. Each dozen is 12, and a half a dozen is 6, so the equation you can use to figure that out is 12 x 2 + 6 = 30.
A dozen is twelve, half a dozen is 6.
A dozen is twelve; a half dozen is therefore six.
One dozen is 12 Half a dozen is 6
A baker's half dozen is a group of seven items, the concept being that it is one more than a half dozen.
One dozen = 12 so half a dozen = 12/2 = 6. So simple!
Oh, dude, half of a dozen is 6, right? So, half of 6 is 3. And then half of 3 is like 1.5. So, half of half of a dozen is 1.5. Math can be fun when you break it down like this!

One dozen equals 12 (items). 6 is one half (1/2) of a dozen. So 6 stars would be one-half dozen if you need how many dozens.
A dozen is twelve, half a dozen is 6.
