30 Time Zones Quiz Questions and Answers

Time zones are geographical regions on Earth that have the same standard time. The Earth is divided into 24 time zones, each approximately 15 degrees of longitude wide, with the Prime Meridian (0 degrees longitude) serving as the reference point. These time zones are established to facilitate consistent timekeeping across different parts of the world.

The Earth rotates 360 degrees in 24 hours, resulting in 15 degrees of rotation per hour. As a result, each time zone represents an hour’s difference in time from the neighboring zone. When you move eastward from one time zone to the next, you gain an hour, and when you move westward, you lose an hour.

The time within a time zone is known as the standard time. However, some regions or countries may observe Daylight Saving Time (DST), which involves advancing the clocks by one hour during certain periods of the year to make better use of daylight. Not all countries observe DST, and its adoption varies around the world.

Time zones are crucial for coordinating activities and scheduling events on a global scale, especially in telecommunications, transportation, and international business. They ensure that people in different parts of the world can communicate and work together efficiently, considering the variations in local times. The use of time zones helps maintain synchronization and consistency in our modern interconnected world.
