The Park hours for August will be released on Feb 1st. Disney is now giving there operating time 6 months out. But I wouldnt rely on them 100% cause they change so much. Heck they just changed EMH last week for January. So its a good to go by calender but you have to keep checking it for constant changes. Cause I would estimate they make 6-8 changes to it before the month actually rolls around.
