Where Does the Sun Rise First?

Although the sun is technically continually rising as the Earth rotates, it can be argued that it rises on a new day first at the International Date Line. Generally speaking, from any vantage point on Earth, the sun rises from the eastern horizon to begin the daylight period.

The International Date Line, an imaginary longitudinal line that is roughly 180 degrees opposite of the Greenwich Meridian, notes the beginning of each day. This line does not run strictly north to south, as it deviates for political considerations; through the Bering Strait, for example, it runs northeast to southwest to divide Alaska from Russia.
