The International Meridian Conference was a conference held in October 1884 in Washington, D.C., in the United States, to determine a prime meridian for international use.[1] The conference was held at the request of U.S. President Chester A. Arthur.[1] The subject to discuss was the choice of "a meridian to be employed as a common zero of longitude and standard of time reckoning throughout the world".[1] It resulted in the recommendation of the Greenwich Meridian as the international standard for zero degrees longitude.[1]
