Local time refers to the specific time observed in a particular area or region, based on its position relative to the Prime Meridian. It is determined by the local longitude and is usually expressed in hours and minutes, often with a designation of AM or PM. Local time can vary significantly from one place to another, especially across different time zones. Time zones are regions of the Earth that have the same standard time. Each time zone is typically one hour apart, with some areas observing Daylight Saving Time to make better use of daylight during certain months. This system helps synchronize activities and schedules within a specific locality.
