Create a baseline company calendar

Is there a way to create a baseline company calendar that has standard
holidays and events in it that would automatically propagate to all other
calendars? This is something that would need to be dynamic in use. In
other words if a new holiday is added, it would propagate to all associated
calendars and if a holiday is removed, it would be removed from all
associated calendars.

We are running Office XP (Outlook 2002 - SP3) with Exchange Server 2000
(SP3) on Windows 2000 (SP3) and Active Directory. All workstations are
running Windows XP (SP1).

Any ideas on this? Can it be done?

Thanks,

Rick
