Apple's Worldwide Developers Conference will kick off on June 13th. The event's date was unveiled in a slightly unusual way this year: through Siri. As spotted by 9to5Mac, asking Siri when WWDC is being held delivers the answer, "The Worldwide Developers Conference (WWDC) will be held June 13 through June 17 in San Francisco. I can't wait!"
Siri may have jumped the gun
The conference's date hasn't been announced on Apple's website yet, which suggests that Siri's information may have gone live a little early. Siri links to Apple's WWDC website when asked for more information, but its website is still displaying information for 2015.
WWDC is where Apple previews the next big releases of iOS and OS X. Hardware news is uncommon — but not unheard of — but as always, you should expect the event to focus on Apple's biggest platforms and how developers can build more interesting apps for them.
