Mark your calendars, Android fans, because Google just revealed when this year’s big I/O developer conference will take place.

Google I/O 2015 will happen on May 28 and May 9 at Moscone Center West in San Francisco, Calif. Registration for the event will kick off March 17 at 9:00 am PT/12:00 pm ET.

I/O is Google’s biggest event of each year and is meant to help developers interact with one another, to get help and learn from Google, and for Google to announce some new developer goodies. There’s typically some exciting stuff in there for non-devs, too, including sneak peeks at an upcoming major release of Android.

What do you hope to see at Google I/O 2015?
