Longitudes are calculated using the prime meridian, counting 180 degrees either east or west.The prime meridian passes through England's Greenwich Observatory.Ordinance 51 (on the precise calculation of time using the Prime Meridian) – July 13, 1886 In 1886, Ordinance 51 was issued in response to this problem, which stated: For example, there is a difference of about 5 degrees longitude between Tokyo and Osaka and because of this, a train that departed from Tokyo would arrive at Osaka 20 minutes behind the time in Tokyo.
