Imagine Math reports distinguish between School Time and Home Time.
School Time is usage between the hours of 7:00 a.m. and 4:00 p.m.
Home Time is the evening and weekend hours. It's usage on weekdays between 4:00 p.m. and 7:00 a.m., and all day Saturday and Sunday.
All hours are according to your local time zone.
Note
These time periods cannot be adjusted.
