Recurring Events is a nice and free gadget that will let you have on your desktop an analog or digital clock and two options, to open a calendar to define events and an alarm button to define alarm modes. You can have an alarm for an event to be repeated e.g. daily.
The gadget lets you customize its background theme. In the image above, for example, I have replaced the original black background with a light texture that I had in my PC.
If you need recurring reminders, and of course, simple reminders, this is a desktop gadget you should try.
