Cirno day is the day we celebrate the birthday of the strongest character in touhou, known as Cirno the ice fairy.
the 9th of September is the date of the Cirno day and is a day that the touhou community celebrates by posting Cirno related content,like memes, pictures of (9) and Cirno fanart.

it's a really important date to the touhou fandom.

You can think of it like the birthday of the touhou fandom, and one of the most important day to celebrate for any touhou fan, along with ZUN 's birthday.
