Time change happens because the earth spins. This means that different parts of the world are facing the sun at different times. For example, when it is morning in America, it’s late at night in Japan.
If you take a non-stop flight from Los Angeles to Bangkok, Thailand at 11:00pm on a Monday, you are on a plane for about 17 hours. When you arrive, your watch will say 4:00pm on Tuesday. But, because of the time difference, it will be 6:00am on Wednesday in Bangkok.
