Today, the FanCons.com convention database has passed the 20,000 convention milestone. The database began in October 2003 to power AnimeCons.com, but expanded beyond anime conventions with the creation of FanCons.com in early 2012. The 10,000th convention was added in December 2017.
The 20,000th convention to be added was LumaCon 2023 which is scheduled to take place in January 2023 in Petaluma, California. LumaCon is a small, free one-day comic convention organized by librarians in Petaluma. The convention is targeted toward kids and features an artists' alley with professional artists mixed in among local student artists. 2023 will be LumaCon's eighth year of in-person events (in addition to two online-only events during the COVID-19 pandemic).
We plan to continue cataloging information on the next 20,000 conventions around the world and adding historical information on past conventions going as far back as the first known fan convention back in 1889. There are still many, many more conventions out there. Any convention organizers who don't see their conventions listed can submit them. After the submission is reviewed for accuracy, the information will be added.
All of the data available through FanCons.com and its affiliated sites (AnimeCons.com, FantasyCons.com, FurryCons.com, HorrorCons.com, SteampunkCons.com, ToyCons.com, and VideoGameCons.com) has been painstakingly entered by hand by a team of unpaid volunteers with an appreciation and love for conventions.
