As an American (California native, living in the Midwest for the last decade), it's not that weird. I hear people using "December 12th" and "12th of December" with about equal frequency. Written, though, "December 12th" is more common, and if you're just using the numbers, everyone will assume the month is first.
My local Costco always gets some amazing avocados. Maybe I'll go there on my lunch break today and pick up a bag, and get myself a hotdog on my way out.
