Nope! 'Tis the other way around. I know because I lost a birthday once (no, didn't really miss it that much) flying to Japan from SFO. I got a day back on the return trip, but the birthday was lost forever.
Heh, I knew what I was trying to say but failed to say it. The best way to think of it is by remembering timezones. On this side of GMT, we are negative, whereas on the otherside, they are positive. (Chicago is -6 hours, whereas Tokyo is +9... so you GAIN a day by going from West to East... thanks for correcting me...
