With a properly designed database schema a single SQL statement would
suffice (not 42 SETLLs), returning the day, month, year and boolean flag for
whether or not there is an appointmnent booked for that day, milliseconds
execution time also. Are suggesting that a procedural program should be
initiated that in turn renders HTML for the days of the calendar with
appointment days flagged, and if so you are also suggesting that this is the
most efficient method you can think off? Wouldn't it be better to bind a
Calendar control to a datasource that provides the information requested?

Every once in awhile I do a "keyboard and mouse usage evaluation".
That's half the battle. How many keystrokes are required to complete a
transaction? How often are your hands moving off the keyboard to the mouse,
and back again? How many times do fields you've keyed scroll out of view?
What does it take to alternate between search, record list, add, change, &
delete modes? What is the wait time between screen transitions? An interface
like SugarCRM wastes a lot of time.
I've begun working on a Daily Planner. I made a mental note of things that
annoy me about Outlook, Google, SugarCRM, and other calendar applications
and finally chose a UI layout that combines a visual calendar, a daily
schedule of meetings, appointments, and events, and a data entry form - all
on one screen - always visible - in the main tab. The calendar is used to
select specific dates and navigate between time periods. Days that have
scheduled items are visually highlighted which requires some behind the
scenes AJAX I/O.
I think it's fine to use the mouse for calendar navigation and date
selection. But after a specific day is selected, I want to be able to keep
my hands on the keyboard to view and maintain scheduled items, alerts, and
notes for the selected day.
