Why the country's in Europe are 5 hours ahead?

Countries in Europe are generally 5 hours ahead of Eastern Standard Time (EST) due to their geographic location relative to the Prime Meridian in Greenwich, England. This time difference is primarily influenced by the Earth's rotation and the establishment of time zones. Most European countries operate on Central European Time (CET), which is UTC+1, and during daylight saving time, they move to Central European Summer Time (CEST), which is UTC+2. As a result, when it is noon in New York (EST), it is 5 PM in many parts of Europe.
