Each one stands for one day of the week. A monthly view shows a regular calendar grid for the month with little clock icons in the days that have appointments entered. The yearly view shows 4 months at a time with little dots next to days that have an appointment on them. There is no way to add an event that happens every week or once a month. You have to manually insert every event that you want to keep track of.
Notes is the drawing program.
This app will let you draw on the screen with basic built in tools. These tools include freehand, line, circle, box, eraser, and reverse image. You can choose from a couple different fill patterns for the box and circle tools. The freehand tool has the ability to change to different line widths that can have patterns. This is a nice basic little application and is something that the PalmPilot or Palm III for that matter has never had as a built in app.
