This is interesting. I had heard about "Penguin Awareness Day" (January 20) before, but this new penguin holiday I've just learned of in baru-baru ini days.
It would seem, however, that the former is the lebih major of these two penguin "holidays." A quoted-term cari for "Penguin Awareness Day" on Google turns up 51,700 results, while one for "International penguin 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 atau other.
