Geographical time zones are regions of the Earth that have the same standard time. They are based on the position of the Earth relative to the Sun, with each zone typically spanning 15 degrees of longitude. This division helps synchronize activities like work and travel across different areas, ensuring that people in various locations can coordinate their schedules effectively. Each time zone is usually one hour ahead or behind its neighboring zones. For example, when it is noon in the Eastern Standard Time zone, it is 11 AM in the Central Standard Time zone. This system allows for a more organized way to manage time globally.
