Calgary and a couple of other organizations go to the Sunday closest to August 9, because if it's a Tuesday in an urban area, it's awkward. Because of availability of ministers, and this year the Prime Minister, and so forth, it's moved, as I say, to the Sunday closest to August 9.
On May 1st, 2007. See this statement in context.
