Hi
I saw this thread and decided to jump in.
We are a homeschool family.
We generally start school between 8 and 8:30am and usually finish up by 12 noon, just in time for lunch.
Somedays we work faster or slower than others though.
On the days that we have appointments, or field trips we simply adjust our time to when it fits in our schedule.
We've even done school in the evenings and on weekends before to make up a short day during the week.
