Day length at the Equator. At latitude 0Â° (the Equator) day length will be approximately 12 hours. Areas on the Equator have a constant 12 hours of day light all year round.
From this graph we can see that the longest day of the year occurs between day 170 and day 180. By checking the values of DAYLIGHT for x between 170 and 180, we find that the longest day occurs on day x=173, or June 22, and that that day is 15 hours and 32 seconds long.
