Outlook-esque "Week View" Calendar

[eluser]derekmichaeljohnson[/eluser]
I'm attempting to create a week view calendar with 7 columns (days of the week) and 8 rows (work hours of the day 9am to 5pm). See this image for an example.

How can I best create a model that would not only populate an array with the hours in a work day (9am to 5pm) but also assign any events (from the db) to that hour, if any? Example:

Code:

array(
  '9am' => 'some event',
  '10am' => '',
  '11am' => 'some other event'
  // all the way to 5pm
);

Thanks in advance!
