In short, the Sun rises in the east and sets in the west because of our planet's rotation.
Does the sun rise exactly in the east?
The Sun rises and sets exactly due east and west only when the circular path of our turn on Earth's surface splits into two equal parts, half in the light and half in the dark. ... Earth's tilt means there are only two days per year that the Sun rises exactly due east.
Where do Sun rises first?
Well, wonder no longer! North of Gisborne, New Zealand, around the coast to Opotiki and inland to Te Urewera National Park, The East Cape has the honour of witnessing the world's first sunrise each and every day.
