Ok, I neglected to mention what I was thinking.  Do the WW have their 
own calendar?  One that would be more accurate?  Possibly one that 
would explain why school always seems to start on a Monday?  I know 
they say the way we keep time is off by a minute every so many years 
(don't remember exactly how many, sorry.)  And then we have our leap 
years.  With all our calendar systems, I could see a different system 
in the WW.  However, doesn't Olivander's say something about having 
started in BC?
