calendar links

i installed a new theme on my blog.

when i click on the calendar dates, it shows only the topic title and date etc but not the full body of the post. like the photo associated with the post. i would like it where if someone clicks on say August 20 it will show all the posts in full, not just the titles of posts that were written on that day?

please see https://www.grayfilm.com/blog for reference on what im talking about. click on any date on the calendar and see what i mean.!!

i tried to do a search using dreamweaver but have been unable to find where in the scripting i would have to alter the code to reflect what i need
