Hi guys,
I'm using Lang-8 but I need to ask lots of questions as my Japanese is very limited!

I want to say:
'I have a day off on either Wednesday or Thursday'

I know the vocab but I don't know the correct usage/position of 'それとも.'

At a guess I'd say:
水曜日かそれとも木曜日は休暇があります。

But I'm sure that's wrong!
