Maybe because it's still early in the year and most of us haven't worked our way up to pronouncing words correctly yet, we all seem to get "February" wrong. It's a little hard done by as a month; it's short, it's cold, and nobody much cares for it, but that shouldn't be an excuse to call it by the wrong name when the right one is staring you in the face. You wouldn't like it if someone did it to you!
We tend to pronounce it very similarly to its neighbor, January, but that doesn't account for the 'r' that appears in the middle of the word, and has no Earthly business being there. Seriously, what other word just drops an 'r' in like that and expects you to deal with it? Because of this, the month is "feb-roo-erry", not "feb-yoo-erry".
