Question

If the sun rises at 6 am and sets at 6 pm how long was the day

Answer 1

Explanation:

On a standard meridian at the equator one might expect the Sun to rise at 6:00 A.M. and set at 6:00 P.M., but the Sun rises at 6:03 A.M. in July, a summer month, and also rises late, at 6:11 A.M. in February, a winter month. It rises seven minutes before 6:00 A.M. in mid-May, and 20 minutes before 6:00 A.M. at the end of October. At the equator these effects are entirely accounted for by the equation of time.
