Since when is a week 14 days long?

Sign in store windows, Aritzia, Pacific Centre, Vancouver, BC (Photo taken January 8, 2016)

I was surprised to see this sign in the window of the Aritzia store in Pacific Centre last Friday. Bowing Week is usually taken to be the week between Christmas day and New Year's Eve. This is not a sign for the Boxing Week Sale, but rather the Boxing Fortnight sale.
