I think the first part of this question is fairly self explanatory but the second half is more confusing so I’ll re-word it here. Is the sun rise time when the sun first peeks above the horizon or when the bottom of the circle stops touching the horizon?
In: Technology
Sunrise is the time when the center of the sun crosses the horizon, and sunset is the time when the center of the sun drops below the horizon.
The sun rising and setting takes a lot longer but the time quoted is when the center line crosses the horizon at your location(assuming you’re at sea level with no obstructions)
The time before sunrise and the time after sunset when its still somewhat light are called twilight. There are three stages of twilight(Civil, Nautical, Astronomical) which are all defined by the angle made with respect to the horizon and the center line of the sun.
Just “Its kinda bright now” isn’t a good enough definition of sunrise when you want to list it for everywhere in the world
