10:30 a.m., sometimes later. Depends on venue availability, coming off a road game, day of home game, etc. There also is the consideration per the CBA that players must receive at least four off days (no games, no practices) per month. I don't know if there is anything in the form of a monthly schedule made public. Oftentimes, the team or a media member will publish via such methods as Twitter though that isn't a guarantee.
