golden hour time
Golden hour is not a clock hour: it is the stretch when the Sun is low and the light is red and soft. When it falls, and for how long, depends on the city and the time of year.
Blue hour: 04:42 to 05:01 and 19:08 to 19:28.
29 minutes each side, against 48 in the default.
Sunrise at 05:16 and sunset at 19:09.
83 minutes each side; blue hour 21:50 to 22:31.
The Sun reaches 2.4° at solar noon, 13:26.
It crosses local midnight.
Pick the city and date above. The time comes from the Sun's position calculated for the city's coordinates, in the city's time zone, with daylight saving time where it applies. In São Paulo on December 21, 2026 the Sun rises at 05:17 and sets at 18:52; on June 21, 2026, at 06:48 and 17:29.
It depends on the city and the date: the tool opens with yours and today's date. As a rule it starts shortly before sunrise and ends shortly after, and in the evening it starts about 30 to 35 minutes before sunset in the Brazilian cities we tested.
Rarely exactly one. In São Paulo it is 48 to 49 minutes; in London, 83 to 87; in Quito, 44. The name is only a popular approximation, and the Sun-altitude range you pick also changes the length.
Golden hour has the Sun still near or above the horizon with warm light; blue hour comes after sunset (or before sunrise), with the Sun 4 to 8 degrees below the horizon and cool, diffuse light. The tool shows both in sequence.
