Hi guys,

Does anybody have an algorithm to calculate the sunrise and sunset of a given lat/lon position and date?

I tried to use the following algorithm: williams.best.vwh.net/sunrise_sunset_algorithm.htm

but when I compare with the results of NOAA I have big differences
http://www.esrl.noaa.gov/gmd/grad/solcalc/sunrise.html

Any kind of help will be much appreciated. Thank you,
nata
