I developed a simple calendar with Cognos.

It can be used to display all kinds of data, we use it to display the status of de load of the datawarehouse.
I used a repeater table. The trick is to give each cell a gridnumber. With a simple formula you can calculate the gridnumber for each day of the year. The formula : [WeekDayNumber] +( ([IsoJaarWeekNr]-?yearweeknr?) * 7)
Placing a list item in the repeater cell and connecting it you can display anything in the grid.
I used a simple javascript to enable the previous (vorig in Dutch) and next (volgend in Dutch) hyperlinks.
Hope you enjoy this solution!
Nice!
