I disagree that the most important information is the month — it really depends on context.

Most dates I work with are near the present day. Scheduling something next week, referring to last week. Very rarely do I exceed the current month unless I am near a month boundary. The current month is nearly always known information.

In this case, the day is the first piece of information I look for (and almost always when I want to know today's date, all I am really asking for is "what day of the month are we on today?").
