Vantage point is described by Merriam Webster as "a position from which something is viewed or considered".
In this definition, how literal is "position" to be taken? I have the feeling this is somewhat flexible, but I'm looking for a word that describes this concept, but specifically (and unambiguously) for a point in time.
Example: When I finally delivered the book back to the library last week, it was already three weeks late.
Here I am considering the situation from the "position" of last week.
