Yes, with a little setup. But never forget that org-mode is the gateway drug of Emacs.

You start using it for the agenda and TODO lists, learn it has spreadsheet functionality that ties in with the arbitrary-precision calculator, start taking notes and exporting them to PDF via LaTeX, writing reports in it with your company letterhead, merging your contacts list, migrating your email into Emacs, and next thing you know you find yourself fifteen pairs of parentheses deep in a custom elisp function that tweaks the date format for that one manager that insists on yy/dd/mm whenever you send your weekly progress report.

Not that I'd know anything about that.
