Not sure if you’re being serious or sarcastic-but the earth is rotating, so the sun isn’t rising over anything, duh.
Go old school, “first light” and “last light”.
Definition of sunrise, as per Merriam-Webster:
1: the apparent rising of the sun above the horizon
also : the accompanying atmospheric effects
2: the time when the upper limb of the sun appears above the horizon as a result of the diurnal rotation of the earth
“Apparent” seems to be key here. We all know the sun doesn’t pop out of the horizon at sunrise or plunge back into it at sundown, but it’s descriptive in appearance, if not in accurate astronomical terms. We do have dawn and dusk for neutral alternatives that eschew the sun altogether, but dawn has been turned into the name of Tony Orlando’s backup group, and I don’t want to know how the race baiters would react to dusk since dusky has been used to describe darker skin tones.
I think I’ll stick to sunrise/sunset which is also a pretty good song about the passing of time.
