The time of dusk is the moment at the very end of astronomical twilight, just before the minimum brightness of the night sky sets in, or may be thought of as the darkest part of evening twilight. [4] However, technically, the three stages of dusk are as follows: At civil dusk, the center of the Sun's disc goes 6° below the horizon in the ...
Observers within 63°26' of the Equator can view twilight twice each day on every date between the month of the autumnal equinox and the month of vernal equinox between astronomical dawn, nautical dawn, or civil dawn, and sunrise as well as between sunset and civil dusk, nautical dusk, or astronomical dusk, i.e., from September 1 to March 31 of ...
Since the electric potential is symmetric with respect to the equator, only the northern hemisphere needs to be considered. The general direction of the potential is from dawn to dusk, and Φ co is the total potential difference. For a transformation from a rotating magnetospheric coordinate system into a non-rotating system, τ must be ...

Predators hunt when their prey is available, and prey try to avoid the times when their principal predators are at large. The temperature may be too high at midday or too low at night. [2]
The phrase is used in widely varying contexts. For example, in 1917, Albert Einstein and David Hilbert had dawn-to-dusk discussions of physics; and they continued their debate in writing, although Felix Klein records that they "talked past each other, as happens not infrequently between simultaneously producing mathematicians."
