Hello, This is one feature built into Windows that I sorely miss when using MacOS - being able to click on the clock and see a fly-out showing a very simple view of the monthly calendar - just the dates in the standard day-of-week columns. I'm sure there's lot's of clever extra functionality that could be added but it definitely shouldn't encroach on a very clean and simple presentation of the monthly dates. Thanks!
