Apple's Worldwide Developers Conference (WWDC) hasn't been formally announced yet, but iOS users have discovered that Siri is giving the date when asked.

As reported earlier by 9to5Mac, if you ask Siri, "When is WWDC?" it will tell you that the event will be held June 13 through June 17 in San Francisco.

It doesn't say where the event will be held, but it's typically at Moscone West and is expected to take place there once again.

Apple' website still has info up for last year's conference, which was held June 8 through 12. The event featured over 100 technical sessions, over 1,000 Apple engineers, hands-on labs, and the Apple Design Awards. Sessions were streamed live.
