Computer Organizers

Does anyone know of any Computer Organizer i can use on the computer(not including Outlook)that will let me put appts in, remind of thing i have to do on a particular day, have all english hoildays in and i am able to put my holidays in, have a notepad etc.

I would also like to print out the appts etc if possible.

I asked this question before, but did not get any useful ideas.
