Xeno, Yves, and Zahara are best friends celebrating one of their own birthdays. They make the following statements...

Xeno, Yves, and Zahara are best friends celebrating one of their own birthdays. They make the following statements:

Xeno says, "It's Yves' birthday!"
Yves says, "It's not Xeno's birthday!"
Zahara whispers, "It's __'s birthday", but so quietly that you can't make out which of the three names she said.

If I told you how many true statements were made, then you still wouldn't know whose birthday it is. Now that you know that, if I told you what Zahara said then you'd know whose birthday it is.

Whose birthday is it?
