In order to avoid splitting a state, county, city, or town with a time-zone boundary.
Can you imagine how you might handle your work schedule, dental appointments, bus schedule,
or the TV prime-time lineup, if your city had two different time zones in it ?
The prime meridian is a line of longitude
It's the lines of longitude which are used to define time zones, not lattitude.
The polar and temperate zones and the tropics.
Time Zones are based on lines of Longitude - with detours to avoid land.
A line of longitude exactly divisible by 15 degrees would be every 15th meridian, such as 0°, 15°, 30°, 45°, etc. These lines help with dividing the Earth into time zones and are commonly used for navigation and mapping purposes.

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.
They do follow the longitude approximately but in some regions there are political reasons for changing them, for example a large part of Russia is on GMT+3 to make things simpler for the people who live there.
There are 24 hours in a day and 360 degrees so the globe is divided into 24 time zones that are 360°/24 = 15 ° wide. Of course the time zones do not follow the longitudes exactly. Different localities may opt to be part of an adjacent time zone for business purposes. Most of western Europe is on the same time zone even though the countries span about 30° of longitude. There are also some locations that choose to follow their own time zone that is half way in between the nearest time zones - such as India and central Australia. The "international date line" follows (roughly) the 180 ° longitude.
Lines of longitude tells us where we are in relation to the Prime Meridian, either to the west or east.For an exact position on Earth, both lines of latitude and longitude (in degrees plus minutes and seconds) are used.
The three lines of longitude that pass through Australia are 138°E, 144°E, and 153°E. They are used to divide the country into different time zones.
