Clarification on the Timing of When Homework is Due

Any time you have homework due on a specific date, it is due before class starts. If there is no class that day, it is due before midnight of that day. So when there is no class on that day, you have the entire day to do it. But if there is class, you have to submit before the start of class.

The reason you have to get it done before class starts is because class will often start with a quiz on the homework topic.
