Just pointing out that any & all of these dates may have slipped due to temporal incursions in the Prime timeline by Romulans and others.
Temporal War leaves its artifacts in terms of non critical deviations - the river of the Prime timeline is very resilient. They key events will happen give or take a few decades.
Also don’t forget that we are living in a period of disinformation and misinformation … our current timeline might be completely corrupted because corporately owned media may just manipulate dates, times and whole periods to ‘readjust’ or rewrite history in the coming decades. What we know as 2023 today may be rewritten or changed in the future to adjust for whatever political, military or social changes that are to come … future historians might get our timeline completely screwed up because of the political and social games we are playing or will play in this timeline.
Or the events are correct but the dates are changed in the future to correspond to whatever political / social changes that will happen after these catastrophic events … like the old saying “history is written by the victors”
