Today the sun sets at 17:44 in Rio de Janeiro, Brazil, after 11 hours and 49 minutes of daylight that began with sunrise at 05:55.

What time does the sun rise in Rio de Janeiro?
Today sunrise in Rio de Janeiro, Brazil is at 05:55, and daylight lasts 11 hours and 49 minutes until sunset at 17:44. The day actually begins earlier: civil twilight starts at 05:33, when the sky brightens while the sun is still below the horizon. Solar noon, when the sun is at its highest, falls at 11:50. Sunrise is the moment the upper edge of the sun appears on the horizon, accounting for atmospheric refraction: the same definition used by astronomical observatories.
What is the difference between the three twilights?
The three twilights differ by how far the sun has dropped below the horizon. Civil twilight reaches 6 degrees: in Rio de Janeiro it ends at 18:07 today, the hour when you can no longer read outdoors without artificial light. Nautical twilight extends to 12 degrees, today until 18:33: while it lasts, the sea horizon stays visible and sextant navigation works. Astronomical twilight ends at 18 degrees, today at 18:59: from then the sky is fully dark and even faint stars appear. In the morning the sequence runs in reverse, starting at 04:41.
