Assignments are always due at 0200 EST on the listed date. After 2am your submission will be considered late, so you may as well take an extra day to turn it in. The syllabus lists the late policy.
Why 2am? Because we want you to attend class and to be reasonably alert when you do so. Past experience indicates that making assignments due at the start of class leads to a largely somnambulist audience that day. Those classes are fun for neither the student nor the professor.
