Day Length for Various Latitudes
The following tables provide year-round hours of daylight at 5
degree intervals from 60°N to 60°S latitude for every 15
day period.
Shing Lam compiled the C code based on a formula published in:
Meeus, Jean. (1991) Astronomical algorithms. Richmond, Va.: Willmann-Bell. ISBN 0943396352
We reorganized the data into these tables.
