Here's a some history for you!

GREAT SEA STORY
The passenger steamer SS Warrimoo was quietly knifing its way through the waters of the mid-Pacific on its way from Vancouver to Australia. The navigator had just finished working out a star fix and brought Captain John DS. Phillips, the result. The Warrimoo's position was LAT 0º 31' N and LONG 179 30' W. The date was 31 December 1899. "Know what this means?" First Mate Payton broke in, "We're only a few miles from the intersection of the Equator and the International Date Line". Captain Phillips was prankish enough to take full advantage of the opportunity for achieving the navigational freak of a lifetime.

He called his navigators to the bridge to check & double check the ship's position. He changed course slightly so as to bear directly on his mark. Then he adjusted the engine speed.

The calm weather & clear night worked in his favor. At mid-night the SS Warrimoo lay on the Equator at exactly the point where it crossed the International Date Line! The consequences of this bizarre position were many:
The forward part (bow) of the ship was in the Southern Hemisphere & in the middle of summer.
The rear (stern) was in the Northern Hemisphere & in the middle of winter.
The date in the aft part of the ship was 31 December 1899.
In the bow (forward) part it was 1 January 1900.

This ship was therefore not only in:
Two different days,
Two different months,
Two different years,
Two different seasons
But in two different centuries - all at the same time!

He blew it!

Technically, the New Century started at midnight of 1/1/1901.  1801 is the first year of the 19th century, and 1900 is the last, although we usually celebrate the nice round number.  Sure, its just a meaningless convention, but so is the calendar. Think of it this way, Jesus was born in 1 AD, not 0 BC.

Crazycarl and HenryC
whoosh what...?
idle hands are the Devils workshop,
now what about you two and these idle hours away from sailing?
Now remember
there are more than one calendar throughout our human history (and herstory)
and some are still alive and being used
so the best we can do is think ONLY about Earth's path around our Sun...
calendars might account for that, BUT...

so with all this idle time gentlemen...let's work on a metric calendar and 'counting/measuring' of time based on a metric system
or perhaps hexadecimal
or octal
what would be appropriate for our quantum computers

jest wondering

That sounds like something to do while sitting in the cockpit waiting for the wind to come up.
