Hi,
is there a reason there is two functions to calculate sunrise?
calcSunRiseUTC seems to return the correct results and is also used in the sample on the linked page:
http://pointofint.blogspot.it/2014/06/sunrise-and-sunset-in-c.html

It may be worthwhile to rename one it if it's legit or remove calcSunriseUTC.

Thanks for the lib!

Cheers
Will

Hi,
just a note on the getDateTime(double minutes, DateTime date) function: it returns null for negative minutes which may be incorrect. Depending on the timezone & location, negative minutes may be correct in which case the returned date should be on the previous day, something like:
if (hour<0){
DateTime negDate = new DateTime(date.Year, date.Month, date.Day, 0, (int)minute, (int)second);
return negDate.AddHours((int)hour);
}
Example would be determining sunrise in UTC for a location like Sydney, Australia,Tokyo etc.

Cheers
Will
