Sometimes it's impossible to find a perfect solution, so we must make a compromise, and define a standard. One good example:
Rule no. 1: 0 divided by x is 0 for all values of x.
Rule no. 2: x divided by x is 1 for all values of x.
Rule no. 3: x divided by 0 is "not defined" for all values of x.
So what about 0 divided by 0? Rule no. 1 says 0, rule no. 2 says 1, rule no. 3 says "not defined". So the professors made a standard and decided that 0 divided by 0 is 1. Is it correct? Is it reasonable? Is it perfect? No to all three, but it's the accepted definition, it's a standard. We have to live with it.

>>>IMO... due to the creation of a year timeline object... Week #53 sound the most logic answer for any western country.. because it isn't the first week of the year, but the last one.. because it starts on the year of 2008
