Merz originally said "This September 24, 2022 will be remembered..." and was corrected.
Given that︅ he wrote "I remember exactly where I was when I got the first message heard︆ about the war in Ukraine and the first pictures have seen of it", it seems︇ very believable that he accidentally said the current month instead of the month of the︈ invasion. It seems less believable that he was making some mysterious numerological prediction.
