I am going to need some help from the audience on this one. If there are any sci-if, time/space continuum freaks out there, this question is for you.
Typically, when I travel from one country to the next, I lose/gain time in the opposite direction when I return. For example, when I fly from the US to Japan, I lose a day, but when I fly back to the States, that time is gained right back again so that time gained/lost during travel cancel each other out.
For this trip, though, I purchased an around-the-world ticket (for its price and convenience). On Friday the 19th, I left Japan and travelled west to Europe on a 12 hour flight, through 7 time zones. After leaving Europe, I will continue to fly west (and for the first time - yay!) across the Atlantic, over another 8 time zones to Chicago and then Des Moines. Lastly, at the end of the summer, I will fly west once more, this time crossing the Pacific (again), back to Japan, and going through 10 time zones in the process.
This brings me to my final conclusion that, all in all, I will cross all of the time zones in the world, going in the same direction, thus successfully gaining another day of life upon the culmination of my travels.
So my questions are, is this possible? Have I calculated this correctly? And on my next birthday, will I actually be 29 and one extra day old?
My hourglass might just might be a bit off...
