Links to Holiday Parades on Oahu.
Also a few craft fairs or other events listed in some of the links:
http://www.pearlharborparade.org/ If you click on: Press Release, it will open a pdf file with info. It says that the Waikiki Holiday Parade is on December 7.
It has been on the Friday after Thanksgiving for many years.
The gohawaii.about link shows two similar parades. One on November 23 (day after Thanksgiving) and one on December 7.
I don't think there are two Waikiki Holiday Parades.
Maybe some locals can check it out.
