The solar day is thus one of twenty-four hours.
2
It actually takes the Earth a little bit less time to rotate (Sidereal vs. solar day).
3
Circadian rhythms can be entrained to periodic cues in the environment including the solar day, food resources, and temperature.
4
Either timer will enable you to determine, with great accuracy, how long it takes for the Sun to revolve around Earth: the solar day.
5
The spectral powers for variations in z over the frequency range 0.26 yr(-1) to 2.1 solar day(-1) are also compatible with no signal.
6
The lunar months, like the solar days, had been diminished by one-half.
7
