If a day had 18 hours instead of 24 hours, there would still be 24 time zones around the world. Each time zone would cover 15 degrees of longitude, just like in the current 24-hour system.
They would be more extreme: winters would be colder and summers would be hotter. The temperate zones would contract, and the polar and tropical zones would expand.
Each time zone would be approximately 18 degrees wide, since the Earth has 360 degrees of longitude and is divided into 20 time zones.
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.
Approximately 15 degrees apart. It would be exactly 15 degrees, but politics gets in the way.
There are 24 time zones in the world, each 15 degrees of longitude apart. This allows for standardized timekeeping across the globe.
The total number of degrees in the tropic zones is 47 degrees, 23.5 degrees north of the equator and 23.5 degrees south of the equator.

No. Tropical zones are between 0 degrees latitude and 23 degrees north or south.
The Earth is divided into 24 time zones, each approximately 15 degrees of longitude wide. This system creates the basis for standard time zones around the world.
