The passenger steamer SS Warrimoo was in the middle of the Pacific on the Equator and 180 degrees away from Grenwich on the International Date Line on New Year's Eve 1899.
The consequences of this position were:
The bow of the ship was in the Southern Hemisphere, in mid summer on the 1st of January 1900.
The stern was in the Northern Hemisphere in mid winter on the 31st of December 1899.
This ship was therefore crossing two different days, two different months, two different years, two different seasons and two different centuries!
