So I have a theory.
Doctor Who returns in August 2014, Doctor Who is always aired on a Saturday. The 50th was on 23rd of November 2013, August 23rd 2014 is a Saturday.
THEORY = DOCTOR WHO RETURNS THE 23RD OF AUGUST!
Thank you for reading my first, short post :D - Helena
UPDATE ON THIS POST:
My theory was correct :D lol
