The 6th day is in fact quite defined as to how long it is as opposed to the other days which are not quite so defined as to duration/time.
We are living in the 6th Day. You, Me, everyone else ever heard of, written of, known of, lives (lived) in the 6th Day.
I am sad that you are unwilling or unable to grasp that concept.
You’re going to have to back up your wild interpretation with something concrete.
I suggest you go to your Strong’s source code dump and get to work.
Maybe you’ll find it useful for something other than lending a false impression.
