The prime meridian was established at an international conference in 1884 and is centered on the Royal Observatory in Greenwich, London. It is used as the reference point for measuring longitude, with lines running north and south. It is not used to determine latitude. The concept of a prime meridian existed before the 1500s, but it was not widely used until the development of navigational tools like the sextant. It does not relate to the changing of days.
