Because my work and home computers were accidentally set to different time zones when I imported Calendar info from one system to the other, I ended up with multiple instances of the same holiday on the same datethree Christmases on December 25th.
Although I can go through the current year and delete the extra holidaysor even all holidaysas soon as I browse to a new year the multiple instances reappear. I searched for an .ini file and searched the Registry but nothing looked related.
How do I get rid of these extra entries?
The easiest way to resolve this is to change your calendar view to By Category and then right-click the Holiday category heading and select Delete.
After you've done that you'll want to reimport the Holidays (just once) by going to Tools | Options | Calendar Options and clicking the Add Holidays button.
Or you could keep the extra holiday entries and just tell your boss you're taking the extra days off.
