Apple's Worldwide Developers Conference may be taking place June 13-17 this year, if Siri is to be believed. The digital assistant acted as a spokeswoman Monday to reveal the dates to inquisitive users who asked, "When is WWDC?" Apple has not updated the WWDC website, but the announcement and dates line up with the company's announcement history.

Siri was enthusiastic for WWDC 2016, which will take place in San Francisco. The exact location was not revealed, but 9to5 Mac speculates that the city's Moscone West convention hall will once again host the huge conference. When Siri was asked about WWDC 2016 earlier in the day, it stated the dates were not announced yet. WWDC 2015, which took place June 8-12, was announced April 14, 2015. That included a WWDC site update. WWDC 2014 was announced April 3, 2014.

With a date and likely venue in place, the next bit of speculation involves the ticket process. Since 2014, developers have had to apply to purchase WWDC tickets within three to four days of the announcement. 

WWDC 2016 will not be the place Apple reveals the iPhone 7. That event will take place in the fall, with September being the most likely month consumers will get their first look at the next generation of iPhones. But Apple Music, iOS 9, OS X El Capitan, WatchOS 2, a Siri update, Apple Pay rollout to the U.K. and improvements to Apple Maps and News were among the news during CEO Tim Cook's WWDC keynote speech in 2015.

Usually dedicated to software, WWDC 2016 could be the event where the new MacBooks are revealed. Updates to the Mac Pro and Mac Mini desktops may also take place at the developers conference, according to AppleInsider. Software will remain the focal point with potential unveiling of updates to iOS 10, tvOS and watchOS. OS X may get an upgrade and a rebranding to macOS at WWDC 2016.
