It’s counterintuitive. Someone says: let’s schedule an event for June 5th. I scroll to June 5th to see if I’m free. I want to click on the day to add the event. Instead you’ve made the default event date “today.” Who puts something in their calendar for today? To set it to June 5th, now I have make the date level open, to screw around with over-sensitive dials.
Needless counterintuitive over-complications.
