International nonbinary day
The International Nonbinary Day is celebrated each 14th of July since 2012 with the aim to celebrate and focus on nonbinary people, their successes and contributions to the world and their issues. Katje, the person who proposed it, described the choice saying that it's precisely in the middle between International Men's Day and International Women's Day. Moreover, the number of months between March and July, and between July and November, is 3, which is numerologically a good number for nonbinary people, according to Katje of "Fierce Femme's Black Market".
Though it is not well known, it is still celebrated and recognized
