Image World Sunrise 2001
The position of the terminator, the boundary between day and night, at 0 hours UT on January 1. Along the part of the terminator west of the prime meridian (the meridian of longitude that passes through Greenwich, England) the Sun is setting, and along the part of the terminator to the east of the prime meridian the Sun is rising. The lightly shaded area is in civil twilight, where the Sun is below the horizon but there is still sufficient light scattered by the atmosphere that it is not completely dark. At this time the Earth is tilted so that the north pole is away from the Sun and is continually in darkness and the south pole, along with most of the continent of Antarctica, is continually in daylight. Image from *GeoClock.

Image USA 2001
The position of the terminator, the boundary between day and night, at first sunrise in the United States on January 1. The lightly shaded area is in civil twilight, the Sun is below the horizon, but there is still is sufficient light scattered by the atmosphere that it is not yet dark. Image from *GeoClock.
