Hetalia Day is a recognized by Hetalia fans as a worldwide fan gathering held on the 24th of every October (or the closest weekend), in whichever town or city a group of fans agree to meet in. The date was set because of United Nations Day. The first Hetalia day was in October of 2009.
Although there have been fan gatherings on other dates, the only one called "official" is on the date announced on hetalia-day.com .
If there is not one near you,don't organize one. A kind of tradition is to submit a group photo after the event to the main organizers, which normally make a slideshow to show that Hetalia fans are friends all around the world, no matter in which country they live, or how old they are.
Many fans see the Hetalia Day as a symbol for world peace too.
Fans typically cosplay at these events, but generally it is not required.
