Something small. I have the time displayed in the menu bar. When you click on it, it reveals the date [shown in pic]. 'View as Analog', 'View as Digital', 'Open Date & Time Preferences'; these can go. In their place, I would like a small calender, preferably re-sizable. Nothing fancy. You click on the time, and a small calender appears. There are separate menu bar apps for calenders, but it would be ideal to incorporate it into just the one.
