Number of Time Zones By Continent

Name the number of time zones that span each continent. *NOTE: This only counts continental portions of countries. Ex. Alaska and Hawaii DO NOT count. *NOTE: The continent of Australia does not include any of the islands of Oceania, only the country of Australia. *NOTE: Turkey counts as part of Europe. I know this often causes confusion. *NOTE: Russia is counted in both Europe and Asia but all the time zones in Russia do not count for both continents. The dividing line between the continents is a timezone line.
