Desktop Calendar is a free tool which displays an editable calendar on your desktop.

After installation, a full month view calendar is displayed on your desktop, then switched to other months or years in a click or two.

That's sort-of useful all by itself, although you do need to keep in mind that the calendar is displayed instead of your desktop icons, not as well (a Win+D hotkey switches from one to the other).

Double-clicking any day enables entering a text note, appointment, reminder, whatever you like. There's nothing advanced, no scheduling or reminder system, the only other option is to assign a background colour for a particular day.

An administrative menu has some extra tools, including importing and exporting calendars to the program's own format, printing them, or customising the calendar display to suit your needs.
