The polar and temperate zones and the tropics.
They are called meridians or timezones.
It's the lines of longitude which are used to define time zones, not lattitude.
The prime meridian is a line of longitude
Time Zones are based on lines of Longitude - with detours to avoid land.
Only on a map. These are imaginary lines.

The Prime Meridian (0 degrees longitude) and the International Date Line (180 degrees longitude) determine time zones across the globe. Time zones are typically one hour apart for every 15 degrees of longitude difference.
There are 24 time zones. The Earth is 360 degrees around the circumference. So, for every 15 degrees of longitude there is one time zone.
rom east to west they are Atlantic Standard Time (AST), Eastern Standard Time (EST), Central Standard Time (CST), Mountain Standard Time (MST), Pacific Standard Time (PST), Alaskan Standard Time (AKST), Hawaii-Aleutian Standard Time (HST), Samoa standard time (UTC-11) and Chamorro Standard Time (UTC+10).
Time zones
Take for example: 75°57′8″W, a line of longitude. We all know that lines of longitude measure the time zones. There are 360 degrees of longitude, and there are 24 hours in a day. Therefore, an hour would be 15 degrees longitude (360/24). 75° would be the number of degrees of longitude. If we take 75 and divide it by 15, we get the number of hours that we want, in this case, 5 hours. 57′ would be the number of minutes. 8″ would be the number of seconds. Sometimes, there are even milliseconds. They are the decimals after the number of
they are useful because in that way you may find easily the climatic zones and their degrees and when joined together with lines of longitude you may find the location of a place.
