^^ Well, here's the story with that particular day in the Calendar.

It was originally "Okama Day", but in recent years the Japanese government decided to rebrand it as "Transgender Day". This has......not been well-received by the Japanese LGBT community, suffice to say. The distinct between an Okama and someone that is Transgender is an issue in Japan, and apparently it is considered incredibly insulting to refer to someone that is Trans as an "Okama".

So most likely, Ishida either doesn't know the distinction or intended it as "Okama Day". But either way, we have a piece of canon material with Nico referring to himself as a man.
