Also the day of the landing depended on weather conditions and the tides.
So not even Eisenhower knew the day it would happen until a few days before. D-Day could’ve been a month later than it was depending on weather conditions.
It’s kinda like Agile for military guys. They get their planners to tell them how long it will take achieve objectives, then decide later which sprint they should start the project.
Based on that plan, they know certain things have to be in place at D-2 or D+3 or whatever. Makes it easier to fill in the dates when the value of “D” has been decided.
