Diary API or source code
<p>I want to develop an application that creates a customized diary, with graphical events in it.
Something like a calendar of the past, that should be browsable with daily, weekly, monthly or yearly formats.
Before programming every detail of something I suppose that must already exist, as you know, is there some api or some source code that I can use?</p>

<p>Can I use the default Calendar to add graphics and maintain past events, with graphics and text, instead of its obvious role of programming future events?</p>

<p>Thank you.</p>
