A World Time Zone Map visually represents the different time zones across the globe. It divides the Earth into 24 time zones, each typically one hour apart, based on the position of the Prime Meridian in Greenwich, England. This map helps people understand the local time in various regions, facilitating international communication and travel. Each time zone is usually defined by its offset from Coordinated Universal Time (UTC). For example, UTC+0 corresponds to Greenwich Mean Time, while UTC-5 represents Eastern Standard Time in the United States. The map also highlights regions that observe daylight saving time, affecting their local time during certain months.
