Hi Nat,

Click the calendar in the upper right hand corner of the screen for any homework date.  You will see directly under the calendar 2 boxes to put in dates.  You need to enter dates as

                mm/dd/yy

You will need a start and end date both, even if you just need one day.  So, you can get when homework was due for any day you were absent or need to do make-up work.  All dates refer to day the assigtnments were either stamped or turned in.
