Worldcon

Worldcon, World Science Fiction Convention, is the principal annual gathering of science fiction fandom — fandom's family reunion. The one, the only, annual world science fiction convention at which the Hugo Awards are given out.

It is an entirely volunteer-run effort.

As a service mark, "Worldcon" should always be capitalized. Technically it may not be necessary for Worldcons held before it was made a service mark, but why split hairs?

Officially sponsored by the the World Science Fiction Society, it is actually run by a different organization each year which has bid to run it and been selected by vote of the membership (see Site Selection).

The Worldcon has been held each year since 1939 (except during 1942–1945 World War II), and moves to a different city each year. It is the oldest convention with a continuing existence. While most of the conventions occur in the United States, the event has also been hosted by Australia, Canada, Germany, Japan, Great Britain, Finland, Ireland, and the Netherlands. And it would have been hosted by New Zealand if not for Covid-19.

Traditionally, the con, when in the United States, was held over Labor Day weekend (Roscoe’s Birthday), a date chosen not only because most fans have the holiday off work but also because it was an unpopular weekend for mundane meetings, giving Worldcon a better position in regard to facilities. However, this is no longer the case, and Worldcon bidders now chose dates any time from midsummer to early fall. (Indeed, Dragoncon’s choice to hold its gate show over Labor Day has caused some Worldcons to deliberately avoid the weekend due to complaints from pros about a conflict.)
