Brazil's Muslim community traces back to Malê communities brought during the transatlantic slave trade, followed by waves of Lebanese and Syrian immigration from the late 1800s onward. Today, the largest concentrations of mosques are in São Paulo's Bras and Pari districts and in Foz do Iguaçu near the tri-border area, alongside smaller but active communities in Curitiba, Rio de Janeiro and the capital, Brasília.
Because Brazil spans four time zones and stretches from just north of the equator to well south of the Tropic of Capricorn, prayer times vary noticeably between a city like Manaus in the Amazon and one like Porto Alegre in the far south — which is exactly why this page calculates times for your selected coordinates rather than showing one fixed national schedule.
Brazil has no single national fatwa council standardizing a local calculation method, so most Brazilian mosques and prayer apps default to the Muslim World League's angles (18° for Fajr, 17° for Isha) — the most widely recognized global standard and a safe default for a country without a dominant local convention.
Yes — cities like Porto Alegre and Curitiba are far enough south that summer (December–February) brings longer daylight hours, similar to how northern-hemisphere countries experience longer fasts in a Northern summer Ramadan.
Brasília sits about 3° further north and on a different longitude, so its solar noon and shadow-length calculations shift by several minutes even on the same calendar day.
Yes — Jumu'ah replaces Dhuhr on Fridays and is generally held close to the calculated Dhuhr time shown above, though individual mosques set their own khutbah start times.
