Hi Wes,
I recently needed a Text/HTML module which would serve up daily devotionals but surprisingly while I could find many fancy content rotators, nothing was available with a month, day of month, day of year, day of week, time block within a day cycle - so, I'm putting the finishing touches on my own this week and will be releasing it with full source as a DNN Forge project on Codeplex. It will be found at www.codeplex.com/contentdejour once I publish it (hopefully by middle of next week).
A few of it's unique features include selection of content by category, hiding the module when no content is available for the period, full token replacement including an option to replace the module title itself with a content specific title, and an option to handle display of multiple items of content for the same month, day, etc. either at random, sequentially, least viewed by user, etc. ISearchable and IPortable are implemented as well. It is a WSP (not compiled) module requiring DNN 4.7 and above.
Unlike some quote of the day/comic of the day modules of the past, no content is provided - it is up to the user to create their own.
