That's the only instant when there is only one calendar date on Earth and not two ...
exactly precisely 12:00:00.00 Noon on the Prime Meridian.
The only time when there are not two calendar dates on earth is the instant
when the time is exactly precisely 12:00:00.00 Noon on the Prime Meridian.
At any instant of time, there are always two calendar dates on the earth, because
the International Date Line doesn't stick to one meridian of longitude, but zigs and
zags its way through the Pacific Ocean between the north and south poles.
Even if the International Date Line coincided strictly with the 180° meridian, all the way
from pole to pole, there would be only one instant of time each 24 hours when there
was not two different calendar dates on the earth. That would be the instant of Midnight
on the International Date Line / Noon on the Prime Meridian.

Ideally, the International Date Line should be the meridian of 180° longitude. Actually, it has been zigged and zagged to avoid cutting across any island or country, since to do so would put two different calendar dates in the same country simultaneously. If the IDL coincided with the 180° meridian, then together with the Prime Meridian, it would form a great circle on the earth, passing through the north and south poles as well as through Greenwich. As it is now, the Prime Meridian, the 180° meridian, and all other meridians of longitude are semi-circles, that begin and end at the poles.
The prime meridian is the zero degree vertical longitude line on the globe of the Earth. An example sentence would be: She used to live close to the prime meridian.
Latitude is the angular distance north or south from the equator of a point on the earth's surface, measured on the meridian of the point. And longitude is an angular distance on the earth's surface, measured east or west from the prime meridian at Greenwich, England, to the meridian passing through a position, expressed in degrees (or hours), minutes, and seconds.Sources:http://dictionary.reference.com/browse/longitudehttp://dictionary.reference.com/browse/latitude
0 degree meridian. It is called the Prime Meridian. It separates the western and eastern hemispheres.
The earth is wider around the equator, not the prime meridian. Hope this helps you :D
A prime meridian is an imaginary line that divides the Earth into Eastern and Western hemispheres .The prime meridian is located across the equator.It is positioned in a Longitude position.
There are several calendars in use presently. Time Zones are calculated from The Prime Meridian, no matter which calendar is in use. All international business and commerce uses the Gregorian calendar. For religious and spiritual dates in calendars other than Gregorian local time is used so time zones are not a concern.

whayt is the answer if the earth has two calendar
The prime meridian is the zero degree vertical longitude line on the globe of the Earth. An example sentence would be: She used to live close to the prime meridian.
That can happen at any hour, or almost at any hour. If you go halfway around the Earth in one direction, your time will be UTC + 12 hours; whereas if you go halfway round the Earth in the opposite direction, your time will be UTC - 12 hours - so, a full day difference.
the place where someone is standing on the earth, defined by his meridian of longitude
The prime meridian divides the Earth into the Eastern Hemisphere and the Western Hemisphere.
Latitude is the angular distance north or south from the equator of a point on the earth's surface, measured on the meridian of the point. And longitude is an angular distance on the earth's surface, measured east or west from the prime meridian at Greenwich, England, to the meridian passing through a position, expressed in degrees (or hours), minutes, and seconds.Sources:http://dictionary.reference.com/browse/longitudehttp://dictionary.reference.com/browse/latitude
A solar calendar is a type of calendar that is based on the position of the Earth in relation to the sun. This means that the calendar is organized around the length of the solar year, which is the time it takes for the Earth to complete one orbit around the sun. Solar calendars are used to keep track of the seasons and to organize events and appointments throughout the year. Some examples of solar calendars include the Gregorian Calendar, the Julian Calendar, and the Hindu Calendar. The solar calendar is the most widely used calendar system in the world and is the standard for civil and commercial purposes.
