SS Warrimoo

It’s truly mind-blowing! On 31 December 1899, the passenger steamer SS Warrimoo was sailing quietly across the mid-Pacific, on its way from Vancouver to Australia.

The navigator finished checking the stars for the ship’s position and gave the result to Captain John D. S. Phillips:
Latitude: 0° 31' N (just north of the Equator)
Longitude: 179° 30' W (near the International Date Line).

First Mate Payton realized something exciting:
"Captain, we’re just a few miles from the point where the Equator and the International Date Line meet!"

The captain saw a chance to do something unforgettable.
He slightly changed the ship’s course and adjusted the speed.
The night was calm, the sky was clear, and the timing was perfect.

At exactly midnight, the SS Warrimoo was positioned so that:

The front of the ship (bow) was in the Southern Hemisphere, enjoying summer.
The back of the ship (stern) was in the Northern Hemisphere, in the middle of winter.
The date at the back was still 31 December 1899.
The date at the front had already become 1 January 1900.

This meant the ship was in:
 Two different days
 Two different months
 Two different years
 Two different seasons
 Two different centuries — all at the same time!
