The Calendar tool links to all other tools in D2L which have Due Date options, so that due dates added in these tools automatically appear in the Calendar.  You can also add your own calendar entries to remind students of due dates, etc. that might not be tied to a tool in D2L.  Here are some tutorials for you on how to use the Calendar tool. Tutorials for students related to the Calendar tool specifically are at the bottom of this page (and also on the D2L for Students page).
