This is interesting. I had heard about "Penguin Awareness Day" (January 20) before, but this new penguin, auk holiday I've just learned of in hivi karibuni days.
It would seem, however, that the former is the zaidi major of these two penguin, auk "holidays." A quoted-term tafuta for "Penguin Awareness Day" on Google turns up 51,700 results, while one for "International penguin, auk Day" results in a mere 347.
Regardless, it's great to have now TWO days on which to celebrate penguins, whether they be of the "Madagascar" verity au other.
