Not sure where this question really belongs...

I have a table with one record = one day. Is there an easy way to present the data in a calendar lookalike fasion in a grid? I don't plan to do direct data entry into the grid, but may want to allow doubleclick() actions, so I'd have to be able to identify indivdual days. And how would it cope with absent records(Holidays)?

The previous version of this app stored one record = one week; the calender interface was easy to do and worked well, it had other issues though.
