Subject:

Is your question:
a) how to generate a calendar of the current month
or
b) how to display the documents for the selected day when clicking on the link in the calendar?

If b), it is not very hard. Look up RestrictToCategory in the online help, that is a URL argement that will display only the specified category from a categorized view. Encapsulate this view using a $$ViewTemplate.
Depending on how you create the link in the calendar, you could either have a regular HTML link, or use onClick to open the view. Or even use jQuery.

If it is a), it is also not very hard. It all depends on how you will put the calendar on the homepage. I would guess that the homepage is loading the HTML for the calendar using an iframe or possibly innerHTML using Javascript. I would have done the latter.
I would just create a simple Lotusscript agent, which when called generates the HTML -- including links/code described in b) above -- and return it to the calling page.
Just create a HTML table, 6 rows with 7 columns in each. Then populate the table with dates in the correct locations. I would give each table cell it's own unique ID (for easy addressing), for exampel the date in the same format that you use in your categorized view. Then it is very easy to use jQuery to read the ID and call the Domino view using that date as RestrictToCategory value.
