March and september: some variance is seen between website data. At sunrise and sunset, one needs to measure from the center point of the sun: day length at equator is always 12 hours at all times of year. June solstice = 24 hours of sunlight n of 66. 5 degrees n (5-6) Max radiation intensity at 23. 5 degrees n, and the max day length everywhere.
