Apple has yet to announce when it will hold its annual Worldwide Developer's Conference (WWDC) for 2013. However, some observers think they've found a clue in the published scheduled for the Moscone Center.
Apple has held WWDC at the Moscone Center for the last decade, making it the likely choice for this year as well. Currently, the venue's published schedule includes four other events, and the only five-day period not booked is June 10-14, making it the obvious choice.
Apple will likely announce the official date before the end of April.
