Anime favorite hairdo celebrated on February 2nd
Some otaku holidays like Moe Day or Yaoi Day rely on Japanese linguistic word play or order of the day and month in the way dates are written. However, regardless of language or local date formatting, I think you can figure out why February second (2/2) was the day selected to pay tribute to the twin tail hair style (aka pig tails). So celebrate the anime favorite hairdo and tie your hair up or at least lend and elastic to someone who can!
