Day. Starting with Comiket 96, the events have been four days long. Both events run daily from 10:00a.m. to 4:00p.m, with corporate booths open until 5:00p.m and the entire convention closing an hour early on the final day of the event. Comiket has been held at Tokyo Big Sight in Ariake, Tokyo since 1996. Comiket 98, which was planned for August 2020, was the event's first cancellation in its history as a result of the COVID-19 pandemic; Comiket 99, which would have been held in December 2020 was instead held in December 2021, two years after the last time it was held, and ran for only two days. Event size Comiket is the largest fan convention in the world, growing from fewer than 10,000 attendees in 1982 to over half a million by 2004. Since 2007, attendee numbers have fluctuated in the region of 500,000 for Winter Comiket and 560,000 for Summer Comiket. Because of the extremely high volume of attendance at Comiket, mobile phone companies set up temporary antennas, while the Tokyo Metro makes special arrangements to accommodate the large crowds. Hour-long queues to enter Comiket during peak hours are common, while some attendees queue up to five hours before the event to ensure early admission. Popular circles are frequently placed near the venue's loading docks so that their queues can extend outside. ComiketPC recommends that first-time attendees arrive in the afternoon to avoid queues. Catalog For every Comiket, a catalog is released that contains information about the event. The catalog includes a list of all participating circles, maps of the convention layout, directions to and from the convention, rules for the convention, results from surveys held among Comiket participants, articles about topics relevant to dōjinshi creators, and one to two pictures ("circle cuts") for every participating circle. It is available in print and DVD-ROM format, and since Comiket 83, is available online behind a partial paywall. Catalogs are made available for sale at stores two weeks before the event. The print version is roughly the size of an average phone book, while the DVD-ROM version includes features such as advanced search functions and a clickable map. To date, there is no English edition of the catalog available, though the catalog does contain a four-page basic guide for attending Comiket in English, Chinese, and Korean. Prior to Comiket 96, a purchased catalog was not required for admission to Comiket
