How do I remove holidays from my calendar in Outlook 2007?

[Guest]

I selected "add holidays" in the calendar options in Outlook 2007 which
created duplicate holidays (I apparently already had the holidays imported
from the previous version of Outlook). The new Outlook 2007 interface makes
screen space an issue, so having these extra holidays is a problem. How do I
remove the holidays without going through each one individually?

use group by category view and delete the holiday category then import them
again or sort by date and select the first holiday, hold shift and click on
the last one imported at the same time.
