"You cannot add holidays directly to a public folder. Instead, add them to your default Calendar folder either by using the Add Holidays method or by importing from a file with the Import and Export Wizard. Then, move or copy the new holiday items to your public folder. The article To remove duplicate holidays from the Calendar folder in Microsoft Outlook describes how to distinguish the newly added items."
