43-year drought at British Open?

Several online stories (perhaps print too) on the upcoming British Open are referring to a 43-year drought since an English player last won on English soil (Tony Jacklin, 1969).
Since the 2012 British Open has yet to be played, wouldn't this be a 42-year drought?
Could someone please explain how and why it's being called a 43-year drought when only 42 have been played since 1969 (but not counting 1969?)

1970-1979...10 years
1980-1989...10 years
1990-1999...10 years
2000-2009...10 years
2010...1 year
2011...1 year
-------------------------------
42 years

 

Could it be some odd date snafu where the 1969 Open could have been played in June and the 2012 Open later in the summer?

 

43 years is not the same as 43 Opens.

 

It's been 43 calendar years. And yes, it hurts to write that.
