Accuracy of computed times
All sunrise, sunset, twilight and magic-hour times on SunAngle are calculated, not transcribed from any observatory. They come from our implementation of NOAA’s public-domain solar-position formulas, which NOAA states are theoretically accurate to about a minute for latitudes between 72°N and 72°S. We spot-validated our implementation against the Hong Kong Observatory and Taiwan CWA official 2026 tables (43 published values; 36 exact; worst deviation 3 minutes) — details and the full table are on the method page.
Real conditions differ
Computed times assume a sea-level horizon and standard atmospheric refraction. Terrain, buildings, haze, and unusual temperature or pressure can shift the moment you actually see the sun by minutes. Nothing on this site should be treated as an official ephemeris: if minutes matter contractually (broadcast, aviation, religious observance), use your national authority’s published tables.
Definitional disclaimer
“Golden hour” and “blue hour” are photography conventions with no scientific definition. We use sun-elevation bands (golden −4° to +6°, blue −6° to −4°) and label them everywhere they appear; other references draw different boundaries, and we note this in the relevant guides. Cross-check bands when switching tools.
Advertising disclosure
SunAngle may display advertising. Ad slots are clearly labeled. Where an ad platform personalizes, it only does so after consent, per our privacy policy.
Affiliate disclosure
Some pages contain affiliate links (marked rel="sponsored nofollow", e.g.,
to tripods and filters). If you buy through one, we may earn a small commission at no extra
cost to you. Affiliate links never influence which gear a guide recommends — most items we
mention carry no link at all. Links currently point to placeholder destinations
(example.com) until real partners are approved.
Content disclaimer
Guides are general information for photographers and filmmakers, written by us, and reflect the sources cited on each page. They are not professional advice — photographic, legal, or otherwise. Questions or corrections: contact us.
