INDIAN GEOGRAPHY

Detailed explanation-1: -The earth has been divided into 24 zones (Because there are 24 hours in a day) depending upon the longitudes. Each time zone differs from the next by 1 hour. The world has been divided into 24 time zones to help with this.

Detailed explanation-2: -This standard time is used all over the country. With respect to businesses at a global level, there should be compatibility between the standard times of various countries. To facilitate this, the world has been divided into 24 time zones. These time zones have been created with reference to the Prime Meridian itself.

Detailed explanation-3: -More Than 24 Time Zones If each time zone were 1 hour apart, there would be 24 in the world. However, the International Date Line (IDL) creates 3 more. Also, several time zones are only 30 or 45 minutes apart, increasing the total number of standard time zones even further.

Detailed explanation-4: -The earth covers an angle of 360° with every rotation within the span of 24 hours. This indicates that it rotates by 15° every hour. Thus, for the purpose of convenience, time zones have been split into 24 equally-spaced time zones although there exist exceptions that consider political boundaries.
