The org agenda viewer will display timestamped events from all files
listed in org-agenda-files.  Set the latter and invoke the agenda
(org-agenda, which is bound to C-c a for me) and select "a".  You can
then view any particular day you may wish.

To make this work for a number of files, Org has to be told which files to look at.  The variable org-agenda-files can be customized to be a list of all such files.
