Howling:Present day year?

My query is which is the year of the present day in Doctor Who?

With Rose Tyler coming back a year after she left, that made me presume every present day story was a year in the future. But then, Human Nature/The Family of Blood, The Pandorica Opens/The Big Bang, The Impossible Astronaut/Day of the Moon, The Wedding of River Song and The Power of Three made it quite confusing.
