About these times

Sunrise and sunset mark the moments the upper limb of the sun crosses the horizon at sea level for Buenos Aires's coordinates. The actual perceived sunrise can vary slightly depending on local elevation, terrain, and atmospheric refraction.

Civil twilight is the period before sunrise and after sunset when the sun is between 0° and 6° below the horizon — there's still enough light for outdoor activities without artificial lighting. Nautical twilight runs to 12° below; the horizon is still visible at sea for navigation. Astronomical twilight runs to 18° below, after which the sky is fully dark for astronomical observation.
