Reverse engineering my intuition, perhaps it's the order of (mental) operations? Very few calendars treat week numbers as a first class citizen, and most emphasize the day of the week unnecessarily, while putting less emphasis on the information we consider important. Let me elaborate.
In Finland there is a heavy reliance on week numbers. When finding a shared free time slot for a meeting you pick a week first. Especially the public sector revolves around weeks and the default user interface is the official desktop paper(!) calendar.
What makes most US-based calendars confusing by default is the different Date/Time format. The Finnish written standard is DD.MM.YYYY with the week starting on Monday.
Localisation doesn't necessarily help. The British mental model clashes with the Finnish tradition in highlighting the "wrong" pieces of information. In spoken Finnish 'month DD' or 'DD' if you're already looking at the same week is the natural order. The British put a lot of emphasis on the day of the week and the order/formatting is also "wrong": 'DAY DD MONTH'.
In the grand mess of global localisation these are tiny details, but many smaller nations, and their citizens, get stubbornly attached to our local peculiarities.
