Forman leaves the United States in a private jet. He flies 4 hours south non-stop and arrives in a new country. He then leaves once more and flies 4 hours south non-stop and arrives in a third country. He accurately logged his departure and arrival times.
When Forman checks his flight log it says the following:
Depart, 9 am Tuesday
Arrive, 1 pm Wednesday
Depart, 2 pm Wednesday
Arrive, 6 pm Tuesday
How could this be?
Forman leaves from Honolulu, Hawaii and flies south to Kiritimati. He then flies south to Bora Bora. The International dateline is oriented such in this area that crossing south, then south again is equivalent to crossing west, then east again. This also works for any location from Hawaii to the Line Islands to the Society Islands.

Or, Maybe it is just too hard.

Not really that good, since you have to have knowledge (that's not common) from outside the puzzle.
Well, it's more of a riddle than a logic problem. Isn't it true of most riddles that you need outside knowledge?

I can't figure anything out for due north, due south. I'm not sure it's possible. You'd have to cross that longtitude and the only way is by flying slightly laterally.
I can't find any rules here. I didn't really read the TOS. I'm flawed. Am I ruining it by posting what I believe to be answers? If so I'd appreciate if someone slapped me on the hand.

AK is in the US, and it straddles the International Date Line - which itself is not straight. There must be some way that you end up on the other side of it and it's magically yesterday.
