In 2014 the world's largest Leather/BDSM/Fetish event, the Folsom Street Fair, will take place on Sunday, September 21 from 11 AM to 6 PM. The Folsom Street Fair is usually held on the last Sunday of September.
Things get back to normal in 2015 with the Folsom Street Fair on Sunday, September 27.
According to Jacob Richards, outgoing Board President, “The decision to move the fair date this year was not taken lightly. When we have a conflict with Sales Force or Oracle Open World, the entire inventory of hotel rooms for the city is sold out. To avoid conflicts with other important events that bring visitors and revenue into San Francisco, we must look at the last two weekends in September. We hope that this announcement will give everyone with plenty of advance notice."
