Golden hour here is when the sun’s altitude is between 6° and the official sunrise or sunset (−0.833°, including refraction). Blue hour is official rise or set down to −6° (civil twilight). Times are in the city’s own time zone, including daylight saving. Algorithm after NOAA’s solar calculator; accuracy is typically within a couple of minutes. Checked 12 Nov 2026.
