You may consider reading Wikipedia's article on sunrise equations. The lead paragraph gives the equation: where: ω o is the hour angle in degrees at either sunrise (when negative value is taken) or sunset (when positive value is taken) in degree (°) φ is the latitude of the observer on the Earth in degrees; δ is the sun declination in degrees. The Internet Archive offers o, freely downloadable books and texts. There is also a collection of million modern eBooks that may be borrowed by anyone with a free account.

Switch RELAY1 "Front Can Lights" { gpio="pin:2" } Switch RELAY2 "South Flood Lights" { gpio="pin:3" } Switch RELAY3 "Relay 3" { gpio="pin:4" } Switch RELAY4 "Relay 4" { gpio="pin" } Switch RELAY5 "Relay 5" { gpio="pin" } Switch RELAY6 "Relay 6" { gpio="pin" } Switch RELAY7 "Relay 7" { gpio="pin   The sunrise and sunset results are theoretically accurate to within a minute for locations between +/- 72° latitude, and within 10 minutes outside of those latitudes. However, due to variations in atmospheric composition, temperature, pressure and conditions, .

"Cos-1" means use the arc cosine key. "Integral hour" means the single hour figure without minutes. Example- "12" not To make things easier first get the GHA of Sunrise using the following formula. You can also simplify the process of getting the GHA by using HO, (with your AP.   Re: Sunrise and Sunset timings Calculation AM | qqaadir | LINK Thank you all of you for your effort, I have solved this Problem by simply Changing the values of longitudes and latitudes in My prayerController class and It's Done.
