How many time zones is the earth divided into?

The Earth is divided into 24 time zones. This division is based on the fact that the Earth rotates once every 24 hours, which is the basis for the 24-hour day. Each time zone typically represents a one-hour difference in mean solar time due to the Earth's rotation. Although certain regions may adjust or combine time zones for practical reasons, such as to accommodate geographical or political boundaries, the standard remains that there are 24 main time zones around the globe. Each time zone is usually centered around 15 degrees of longitude apart. This organization helps to synchronize time across different regions and is fundamental for global travel, communication, and business operations.
