The topic is fascinating, but the writing… I’m not familiar with WebExhibits, but that article is barely readable, a collection of copy-paste that have little overall consistency: the number of days and names of months is repeated for no apparent reasons; changes are not summarised. I don't think anyone can make sense of the examples, and references to those are not clear either.
