Starting and finishing in London, if you were to circle the globe in a day, how many time zones would you go through, and in which country would you change the date on your watch?

Excepting some local variation, there are 24 time zones, one for each hour in the day. The International Date Line is an imaginary, irregular line drawn through the Pacific. If you began and ended in London, and made the trip in one day, there would be no reason to change your watch, as you would still be on London time. http://www.infoplease.com/ipa/A0002063.html In 1884 the International Meridian Conference divided the world into 24 time zones, but this has occasionally been adjusted for practical purposes. If you circled the globe in a day, beginning and ending in London, you would return one day later than you started, and your watch would show that one day had passed. This would mean it would show the correct date without being changed. My son has pointed out to me that if you circled the globe in a north-south direction, over the poles, you would not pass through all time zones. Jul 10 08, 10:25 PM
