When I say to Siri "When is my Birthday", the response is May 20th, which is correct.

However, when I say "How many days until my birthday" the response uses September 16th as the birthday. How do I fix this?

I am seeing the same problem on my iPhone 4S running iOS 6.0. I say "How many days until my birthday" and the answer from Wolfram Alpha uses September 16, 2013 as my birthday (which it is not). – bneely Dec 13 '12 at 4:44

This is most likely a bug that either Apple or Wolfram Alpha will have to fix. I reported the bug at .
