Turns out there are 7 Canadian years in every Earth year.
All canines were invented in Canada, hence the name. When invented, canine internal clocks were set to run to Canadian time.
As Canines, or dogs as we now call them, became popular, they were transported across the globe on ships that used them to tell the time and as maritime calenders. Every time the dog celebrated a birthday, the sailors knew that 52.14 days had elapsed.
Interestingly, modern day mobile phone companies that force you into a 3yr contract are also know as dogs.
