A day to celebrate twintails, held on February 2. Promoted by the Japan Twintail Assocation since 2012, when it was also approved by the Japan Anniversary Association.
Twintail day in Japanese has small spikes in every November. This is because November 22nd is also celebrated as "Good Twintail Day" ( いいツインテールの日 or いいツインテの日) by some people. It is based on the same manner or wordplay to that of Good Knee High Socks Day which reads "11" as "Good" or "Happy".
