Greenwich Mean Time

Greenwich Mean Time (GMT) is a time standard originally based on the position of the Sun over the Royal Observatory in Greenwich, London. It serves as a reference point for timekeeping worldwide. GMT divides the world into time zones, with each zone typically one hour ahead or behind GMT, depending on its geographical location. This allows countries to synchronize their clocks and manage time efficiently. Though GMT is increasingly replaced by Coordinated Universal Time (UTC), which is more precise, many still use GMT in casual contexts and for scheduling purposes, especially in travel and broadcasting.
