I hope this doesn't go against the rules but I was curious on peoples views. I've had this discussion with a friend on a few occasions and I am of the view that remembering specific dates of historical events is (comparatively) inconsequential to knowing or being able to discern the significance of those events or people. For example: I think it is far less important to know that Constantinople fell to the Ottomans on 29 May, 1453 than knowing what consequences this had for the history of the region (be it political, cultural, religious, or geo-strategic). Just curious if people would think I'm out to lunch on this. Particularly if there are history teachers / professors on here who could comment.
I'm with you. My interest is being able to know the general flow of historical events and the why, what, and how. I am satisfied knowing the order of events when it comes to the "when." Not necessarily the exact dates.
Being able to parrot the date something happened is one thing but being able to understand the causes and effects of the event in question is far more valuable in my opinion.
I agree that knowing the significance of events and what happened in the events is much more important then knowing the dates of events. That being said I also think that knowing the generally time something happened is helpful when looking at it in the context of the time. I don't need to know that Constantinople fell on May 29, 1453, but knowing that Constantinople fell in May of 1453, or even that it fell in 1453 can help place it in the context of the times which will help you better understand the event.
I agree to an extent and it's an issue I've had with school history all the way up to university level (where it changed completely). Knowing roughly what happened and in what order, as well as preferably also some consequences, is vastly more important than knowing exactly when it happened. This is a discussion I have with myself every know and then too because I do still think that some dates are important to know about. To give some examples:
To comment on your example, I do agree that knowing that Constantinople fell to the Ottomans on 29 May, 1453 is redundant, but I do think that knowing that the last Roman outpost fell in 1453 is important.
