A university researcher from Canada has designed a website specifically to help travelers avoid jet lag.
Plug in your itinerary, as well as the times you usually go to sleep and wake up. After you add when you want to start shifting your sleep schedule, the site gives you the best times down to the hour for when you should seek to be out, and when you should sleep.
The website is called "Jet Lag Rooster" and can be found at the following address:
