When Lisbeth is asked by the prosecutor when the assaults on her by Bjurman occurred, she states that the first one was on Tuesday, February 18, 2008, and the second took place Friday March 7, 2008. Now although the seventh of March did take place on a Friday. the 18th of February that year was actually a Monday, But the thing is, since Lisbeth was born in 1981, and told Bjurman at one stage that she was 24, and this is just before the two attacks, the year should have been 2005 or 2006, given that Mikael at that time was investigating the supposed murder of Harriet that occurred in 1966, and the claim was made that this was forty years ago, although that could be rounding up or down.
