What are high school timetables like in the U.S.?

I want to know in as much detail as possible, but basics are fine too.
Which days?
From when till when?
How many lessons and break times, and when?
What lessons a day and how long are they?
Do you have days where you have more of a focus on one topic than another? Like in the UK, we do extra sports on Wednesday.
Anything else that might be interesting to a Brit :)

Many thanks!
