Time Zone is a region of the world that follows the same standard time. The Earth is divided into 24 time zones based on longitude, with each zone typically one hour apart. Time zones help people in different parts of the world stay organized by using local time based on the position of the sun. For example, when it’s 8:00 a.m. in the Philippines (UTC+8), it’s still nighttime in countries like the United Kingdom (UTC+0).
