And we are going to say “A year ago” or “11 months ago”. We are not going to say, “Almost a year ago”.
If I want to let people know that the one-year anniversary of an event worthy of celebration is looming, I don’t see why I wouldn’t tell them that it happened almost a year ago. I might phrase it in a different way because of the constraints of language, but there’s nothing in either my real-life culture or the fictional Star Trek Klingons’ culture that constrains me from saying it at all.
