いいニーハイの日 ニーハイの日
(Nice) Knee Socks Day, also called [b](Nice) Thighhighs Day[/b] or Nice Kneehighs Day, occurs on two dates: Nov 28th and Feb 8th.
These are used to celebrate [[thighhighs]]  and [[over-kneehighs|over-knee socks]]. Mostly this is equivalent with celebrating [[zettai ryouiki]], especially in the 2D realm.

 Thighhighs and over-knee socks are collectively called ニーハイ ([i]nihai[/i]) in Japanese; these dates were thus chosen as [[date pun|word play]]: Nov 28th => 1 ([i]ichi[/i]) - 1 ([i]ichi[/i]) - 2 ([i]ni[/i]) - 8 ([i]ha(ch)i[/i]) = [i]ii ni-hai[/i]; Feb 8th => 2 ([i]ni[/i]) - 8 ([i]ha(ch)i[/i]) = [i]ni-hai[/i]

Note that this day isn't about the legwear in English/on Danbooru called "kneehighs", since the term ニーハイ is only used in above sense of just-above-knee length (aka over-[i][b]kneehigh[/b][/i]) to mid-thigh socks, as a kind of "wasei-eigo":[https://en.wikipedia.org/wiki/Wasei-eigo]. (Calf-/below-knee length socks are ハイソックス = [i]high socks[/i]. サイハイソックス = [i]thigh-high socks[/i] also exists, but only refers to socks that are almost leg length and thus have the appearance of tights (via the same logic as ニーハイソックス where the [i]high[/i] part is used to mean "cover"-length rather than "reach"-length), so they aren't usually counted for zettai ryouiki).
