The Academic Calendar is the go-to place for everything deadlines. It is a tool widely used by students, faculty and staff. Every deadline imaginable is on this document. The Academic Calendar is located on the Registrar's website and is available as a .pdf and as a Google Calendar. It is important to reference this document often as the dates sometimes change.
It is strongly recommended to "add" this calendar to your work and department's Google Calendar. When visiting a Google Calendar, click on the + icon on the bottom-right of that calendar.
