Current time in Niteroi, Brazil right now

It is 2:22 am in Niteroi, Brazil 🇧🇷 right now, on Monday, September 28, 2026. The city keeps America/Sao_Paulo, which is BRT at UTC-3, so Niteroi is 3 hours behind of UTC, where it is 5:22 am. The sun rose in Niteroi at 5:36 am and sets at 5:50 pm, which is 12 hours 14 minutes of daylight.

What time is it in Niteroi right now?

The time in Niteroi, Brazil is 2:22 am, 02:22 on a 24 hour clock, on Monday September 28, 2026. The reading above ticks from your own device against the America/Sao_Paulo rules, so it stays right through a clock change rather than drifting an hour out twice a year.

Niteroi sits at 22.88 degrees south and 43.10 degrees west, inside the tropics, south of the equator and 2,545 km from the equator. Its clock is set to a zone whose nominal meridian is 45.0 degrees west, and the city itself is 1.9 degrees east of that line. Those 1.9 degrees are worth 7 minutes 35 seconds of sun time, which is most of why solar noon here lands at 11:43 am rather than on the stroke of twelve.

Niteroi time zone and UTC offset

The IANA zone for Niteroi, Brazil is America/Sao_Paulo. Right now it is running at UTC-3 and the abbreviation in force is BRT. Niteroi does not change its clocks at any point in the year. The offset stays at UTC-3 in January and in July alike, so no conversion involving Niteroi ever needs a seasonal footnote.

Daylight hours in Niteroi today

The sun rose in Niteroi at 5:36 am and sets at 5:50 pm, which is 12 hours 14 minutes of daylight. Solar noon, the instant the sun stands at its highest over Niteroi, is at 11:43 am, which is 17 minutes before clock noon. The sun's declination today is -2.18 degrees, so at this latitude it reaches about 69.3 degrees above the horizon at its highest, to the north.

Where Niteroi is on the map

The marker sits at the coordinates this whole page is computed from, so the sun times, the distances and the solar noon above all belong to this exact point rather than to the wider metropolitan area.

Time difference between Niteroi and major cities

Every row below is computed at this instant, so daylight saving on either side is already in it. A positive figure means that city's clock reads later than Niteroi.

Best time to call Niteroi

Treating a working day as 9am to 6pm on both sides, this is the window the two cities genuinely share. Some of these pairs have no shared working hour at all, which is worth knowing before a meeting is proposed.

Cities on America/Sao_Paulo time

293 of our cities keep America/Sao_Paulo, so every one of them reads 2:22 am at this moment and changes its clocks on the same night as Niteroi. Nearest first:

Moon phase over Niteroi tonight

The moon is a waning gibbous tonight, 17.1 days into its cycle and about 94% lit. The next full moon falls on October 26, 2026 at 1:11 am Sao Paulo time, and the next new moon on October 10, 2026 at 12:49 pm. Both are the same instant everywhere on Earth, printed here on the Niteroi clock, which is why the calendar date can differ from the one a reader further east or west sees.

When the clocks change in Niteroi

There is no clock change scheduled in America/Sao_Paulo within the next 400 days, so Niteroi stays at UTC-3 for the whole of that stretch.

That makes Niteroi an easy city to schedule against: a meeting fixed at a given hour here holds its relationship to UTC all year, and only the other end of the call can move.

How far Niteroi is from other cities

Great-circle distance, computed from the coordinates rather than road mileage. The nearest city we cover to Niteroi is Rio de Janeiro, Brazil at 8 km, and the furthest is Uruma, Japan at 19,023 km, which is 95% of the way to being exactly opposite.

The antipode of Niteroi

Dig straight through the centre of the Earth from Niteroi, Brazil and you come out at 22.88 degrees north, 136.90 degrees east. That point is near Uruma, Japan. The nearest city in our catalogue to it is Uruma, Japan, 992 km away from the antipode itself, where the clock currently reads 2:22 pm on Monday.

The antipode is worked out by flipping the latitude across the equator and swinging the longitude a half turn: 22.88 degrees south becomes 22.88 degrees north, and 43.10 degrees west becomes 136.90 degrees east. Two thirds of the planet is ocean and the land is unevenly spread, so most antipodes are open water: Niteroi is one of the exceptions, with dry land on the far side. The local time at the antipode runs close to UTC+9, roughly twelve hours from Niteroi, because a half turn of longitude is a half turn of the day.

Sunrise and sunset in Niteroi

Today the sun rises in Niteroi at 5:36 am and sets at 5:50 pm, giving 12 hours 14 minutes of daylight. The dedicated page for this city carries the month by month table, the longest and shortest days of 2026, the golden and blue hour bands at both ends of the day, and all three twilight stages: sunrise and sunset times in Niteroi.

Sun and moon in Niteroi today

The sun is up in Niteroi for 12 hours 14 minutes today, from 5:36 am to 5:50 pm. The moon sets in Niteroi at 6:32 am and comes up again at 7:56 pm. The next phase is the last quarter on October 3, 2026. It is 95% lit at the moment, a waning gibbous, thinning by about 4.5 percentage points a day.

Twilight is graded by how far the sun has dropped below the horizon. Civil twilight ends six degrees down, which is roughly the point at which you need a light to read outside. Nautical twilight ends at twelve degrees, when the horizon at sea stops being usable for a sextant sight. Astronomical twilight ends at eighteen degrees, which is full darkness for an observer.

Golden hour is the stretch with the sun between six degrees above the horizon and four below it, and blue hour runs from there down to six degrees below. Neither is literally an hour: each is as long as the sun takes to cross those few degrees, which is minutes near the equator and can be most of the evening at high latitude.

Moonrise and moonset are computed to the moment the moon's upper edge touches a flat horizon, allowing for refraction, for the size of the disc and for the moon's parallax, which together put the centre of the moon at 0.125 degrees above the horizon at the instant it rises. That is a different horizon from the one sunrise uses, and it is why a moonrise time cannot be worked out with a sunrise formula.

Prayer times in Niteroi

Seven days from September 28, 2026, computed for Niteroi, Brazil at 22.88 degrees south, 43.10 degrees west, on the clock of America/Sao_Paulo. The method is Muslim World League (Muslim World League, Mecca), which puts Fajr at 18.0 degrees below the horizon and Isha at 17.0 degrees. Asr uses the Standard shadow ratio of 1, which is the Shafi'i, Maliki and Hanbali position.

Dhuhr is solar noon at Niteroi, Brazil, the instant the Sun crosses the local meridian, so it moves with longitude inside the time zone and with the equation of time through the year rather than sitting at a fixed clock reading. Sunrise and Maghrib are the standard refracted horizon, the same 0.833 degrees every almanac uses. Every figure above is computed from the Sun's position for this exact coordinate; none of it is copied from a table.

Different methods disagree, and that is expected rather than an error. Fajr under ISNA at 15 degrees comes later than Fajr under Egyptian General Authority of Survey at 19.5 degrees, by twenty minutes or more depending on latitude and season. Follow whichever your local mosque follows.

Qibla direction from Niteroi

From Niteroi, Brazil the qibla is 67.6 degrees on a true compass, which is east-northeast, or 22.4 degrees north of due east. The Kaaba is 10,240 km away, 6,363 miles, measured over the surface of the Earth.

That figure is the initial bearing of the great circle from Niteroi, Brazil to 21.4225 degrees north, 39.8262 degrees east, which is the Kaaba inside Masjid al-Haram.

The bearing is measured from true north, not magnetic north. A magnetic compass points at the magnetic pole, and the difference between the two can be anything from nothing to more than twenty degrees depending where you are, so check your compass reading against magnetic declination for Niteroi, Brazil before you use it. A phone compass set to true north, or the shadow of a vertical stick at local solar noon, avoids the problem entirely.
