If you're being that precise the calendar actually has an average of 365.2425 days per year and not 365.25. In fact that was the major motivation for switching from the Julian Calendar a full 430 years ago.
Or, if you're being really precise, you'd say 24/7/52... </pedantry>
I was expecting this kind of comments if I had only written 365 days a year, thought I was covered, apparently not.
I was just kind of surprised to see the .25. If you had put just 365 I'd have read that as "a year" and not give it a second thought. Instead it got me thinking if it actually rounded out to .25 or not so I went and checked. Apparently that wasn't too appreciated... :) No offense intended.
I think the pedantry was invited by the attempt at specifics. C'est la vie.
