Those of you who home school did you do lessons all summer long or took the three months off?

When it was mentioned on the evening news that school was beginning for a lot of students in the morning, marking the end of summer vacation. It made me think if those who home school follow the scheduling of mainstream schools. Do you who home school start class at 8:30 to 9am in the morning? Do you suspend lesson for Spring break or Christmas? Do your kids do lesson 6 hours a day at home or do you break it up in chunks? Do you have an official start and stop times for lessons, or is it malleable and flexible? During the summer months do you suspend lessons until Sept.?
