When do do the weekly options start?

Hi,
Which days of the month do the new weekly options start trading? I would have thought the new weekly July 2012 SPY options would have been available yesterday or today.
Thanks.

Hi,
I read that before posting. Does that mean the the next SPY options to be listed will be the July 6 expiration which will be listed on June 28th?
Thanks.

 

Yes ...... And no weeklies during the regular series of options.
