Maybe I'm the only one, but I have a mental picture of my calendar using the upper-right quadrant of a Cartesian Plane. Days are on the X axis, Hours are on the Y axis. Events go from bottom-up instead of top-down like in all physical day-planners. I formed this mental model when I was very young, which may explain why I can't stand any calendaring apps today.

Does anyone else do this? I've seriously considered contacting a calendar manufacturing company to print "Cartesian Calendars" in this manner... or if any such thing already exists, please let me know!

well, you could just add a negative sign in from of the times and just write bottom up with a standard calendar
