In Emacs' org-mode, any way to hide the subtree with timestamp not set to today?

I just started to learn org-mode (and *Emacs*) and I plan to use it as a *calendar/timetable/todo-list* hybrid. Is it possible to hide entries with timestamp not set to today? If so, how? For example, say if today is 2014-09-18: * Lunch * TODO Call boss ** Report :: Nothing happened * TODO Call Bob ; This entry will not be shown ; This entry will not be shown ; This entry will not be shown ** Discuss :: Project Alice ; This entry will not be shown ** Discuss :: Upgrading to CentOS 5 ; This entry will not be shown * TODO Fetch Claire from school Incidentally, are there any more efficient way to deal with calendar/timetable/todo-lists in org-mode?
