What does atmospheric refraction mean for the length of daylight?

It advances the sunrise and delays the sunset, adding nearly another six minutes of daylight at mid-temperate latitudes. Hence, more daylight than night at the equinox. Astronomical almanacs usually don't give sunrise or sunset times to the second.

Answer:

the time or date (twice each year) at which the sun crosses the celestial equator, when day and night are of approximately equal length (about 22 September and 20 March).

There's slightly more day than night on the day of an equinox. That's because the sun is a disk, not a point of light, and because Earth's atmosphere refracts (bends) sunlight.
