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.

Whose birthday is it?
