Today is November 28th. In Japan, it’s unofficially Nice Knee-High Socks Day. This is because the date forms a pun in Japanese. Writing the date as 11/28, or 1-1-2-8, the Japanese for the numbers would be “ichi-ichi-ni-hachi.” Shortening it by dropping the second syllables and adjusting the final sound, you get “ii ni-hai,” or “nice knee-high socks.”
A lot of people post pictures, which I think is nice.
