I don't know why I'm having such a hard time wrapping my head around the thinking here. What I want to determine is: if you could buy something anywhere in the world, as long as you bought it on February 10th, how long would the planet have, in total? Ie, how long does February 10th last, starting at the International Dateline and then going all the way around?
as a baseline, New Years Day 2012, for example, starts at 5am on a Monday in Samoa. Then it happens everywhere else, obviously going all the way around the world and hitting American Samoa at 6am on a Tuesday. So is it 29 hours for that + 24 hours in a day? Is it that easy?
I could be missing something incredibly obvious here, or possibly I just lack basic math, but this is currently stumping me and my entire office. And google sucks for questions you don't know how to ask.
