Why the places located relatively eastward experience a new day first?

The places located relatively eastward do not experience a new day first. In fact, the places located relatively westward experience a new day first. This is because the Earth rotates from west to east, so the eastern side of the Earth is always facing the sun, while the western side is always facing away from the sun. As the Earth rotates, the eastern side moves into the sunlight, while the western side moves into darkness. This means that the places located relatively westward are the first to experience a new day, while the places located relatively eastward are the last to experience a new day.
