For 2000 to 2009 you say it like "two thousand and nine". For 2010 and above, you say it like "twenty ten".

I think most people here would say 'two thousand fourteen', but when this question has come up before people have said 'twenty fourteen'. It might be a regional thing.

Twenty fourteen.

Either, "two thousand fourteen" or maybe "twenty fourteen"... but I think the first is more common.

Is the question specifically about the year, or about the number in general?
