First time I've read any of his writing. Initial thought was it must be an attempt at humour, but bits of it read as a genuine gripe (perhaps veiled in humour). Poe's Law applies heavily in these situations (intersection of Microsoft, US world views, international standards, Europe). ISO8601's definition of the first week is particularly relevant, as many of his comments relate to when a week starts (he believes it starts on a Sunday), and when the first week of the year starts (AFAICT he seems to think it's whatever week has the 1st of January in it). The 'dates in a particular culture' is the entirety of what this article is about. The 'Danish culture' doesn't treat dates peculiarly - they align with ISO8601 by the looks of it. It seems to be more of a discussion of dates in the US culture.
