Homework is due the day after it is assigned.  For example. if the item on the calendar for today says "Workbook page 1 #1" that means that Workbook page 1 #1 is the homework for tonight, due tomorrow in class.  If the calendar lists a quiz, it is given the day on which it is listed.  Most quizzes are on Fridays, but not all.
