I was wondering how it is flying from San Francisco to Manila in terms of jetlag. If the flight leaves at 10PM and arrives at 6 AM via Guam in the winter would you see any light? On the return trip the flight arrives at SFO at 6 PM so would you see light on the return trip?

I saw on a world clock that Manila and San Francisco have a 15 hour time difference but when subtracting it was like 8 hours? My question is how many hours different is MNL and SFO? How does the International Date Line affect jetlag?

If I made the trip from SFO-Israel without any real jetlag would a trip to Asia be easier or harder?

If I sleep after the meal service on the outbound and return trips and wake up before arriving SFO like midway how would my jetlag be?

If a flight arrives in the morning around 8 or 9 from Australia and you slept on the plane and woke up just before breakfast would you be on schedule by staying up all day since the day begins then?

Any tips on how to make a flight from MNL either via HKG or MNL? At what point of the flight should I be awake and at what point should I be asleep? I can sleep on planes most of the time.

I would like to do a trip in the winter.

Thanks for the tips.
