Sunrise usually represents a new life or hope, whereas sunset often symbolizes a life that is about to end or the ephemerality of existence.

Here's what scientists say about "sunrise" and "sunset": The sun stays in its position at the center of our solar system. It doesn't rise and set. But it appears to rise and set because of the Earth's rotation on its axis.

In “Sunrise, Sunset” a young mother, Jeanne, struggles with postpartum depression while her own mother slips further into dementia. A moment of near-violence creates a crescendo that brings Jeanne into a realization of what she has lost and what she has gained.

Refraction in the air causes the phenomenon of advanced sunrise and delayed sunset. In this scenario, the Sun appears to rise 2 minutes earlier and set 2 minutes later. The Sun's rays are refracted when they strike the atmosphere. As a result, the Sun appears to be in a position indicating that it has already risen.
