Peter Capaldi is counting down the days until Doctor Who debut Deep Breath - and today's the big day

Doctor Who fans are not the only ones watching the clock this week – the Doctor himself is counting down the days until Peter Capaldi's debut on Saturday.

Given that this is the week before series eight opener Deep Breath premieres on BBC1, the BBC are releasing a short teaser video a day to build up excitement for the show's return.

It's Doctor Who eve! It's like Christmas eve, but better. And as such, there's a new teaser to get excited by: the Doctor, once again, using his Tardis' handy array of billowing paper to remind us that there's just one day to go…

We've finally made it! The countdown has reached zero, and we all know what that means: it's Doctor Who day! The Doctor himself is excited too, of course, and has decided to break all of our screens to prove it.

It's only a matter of hours now. Sit back, relax and take a deep breath...
