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.

What does the prime meridian and international dateline combine to do?

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.

What hour position of the prime meridian does the earth have two dates?

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.

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.
