WebThen, considering that the hour angle at local solar noon is 0°, with each 15° of longitude equivalent to 1 h, the sunrise and sunset time in hours from local solar noon is then 6.68 h. In consequence, the sunrise is at 5.32 (5:19:12 in h:m:s format) and the sunset at 18.68 (18:40:48), being the day length 13.36 h (13:21:36).
