Eclipse calendar 2026 to 2035

The complete calendar of solar and lunar eclipses from 2026 to 2035, calculated on our own server in Brasília time (UTC-3). For every eclipse you get the type, the magnitude and whether it is visible from the 27 Brazilian state capitals: for solar eclipses, how much of the Sun the Moon covers in each city; for lunar eclipses, whether the Moon is above the horizon while it happens.

All eclipses from 2026 to 2035

There are 45 eclipses in ten years: 22 solar and 23 lunar. Dates and times are in Brasília time, which can be a different day than the UTC date.

Magnitude: for partial solar eclipses, the fraction of the Sun's diameter covered by the Moon; for total and annular ones, the ratio of the apparent diameters of the Moon and the Sun (above 1 for total, below 1 for annular). For lunar eclipses, the fraction of the Moon's diameter inside the umbra (1 or more means total) or the penumbra. "Partly" means that only some capitals see the whole phenomenon.

Types of eclipse

A solar eclipse happens at new Moon, when the Moon passes between the Earth and the Sun and its shadow falls on the Earth. A lunar eclipse happens at full Moon, when the Moon moves through the Earth's shadow.

• Total solar eclipse: the Moon covers the whole Sun, as seen from inside the umbra, a strip usually well under 270 km wide. Outside it, the eclipse is partial.
• Annular solar eclipse: the Moon is near the farthest point of its orbit and looks slightly smaller than the Sun, leaving a bright ring around it.
• Partial solar eclipse: only the penumbra reaches the observer, and the Moon covers just part of the Sun. Every central eclipse looks partial away from its path.
• Hybrid solar eclipse: it is annular at some points of its path and total at others, because of the curvature of the Earth.
• Total lunar eclipse: the whole Moon enters the umbra and turns coppery red, lit by sunlight bent through the Earth's atmosphere.
• Partial lunar eclipse: only part of the Moon enters the umbra.
• Penumbral lunar eclipse: the Moon only crosses the penumbra and dims very slightly, which is usually hard to notice by eye.

Why there is not an eclipse every month

The Moon's orbit is tilted about 5.1° to the Earth's orbit, so at most new and full Moons the shadow passes above or below. An eclipse needs the new or full Moon to fall near one of the two nodes, the points where the Moon's orbit crosses the plane of the Earth's orbit. That happens in two "eclipse seasons" a year, about 173 days apart, and each season brings one to three eclipses. A year has between 4 and 7 eclipses in total.

Why a total solar eclipse is so rare in any one place

The Sun is about 400 times wider than the Moon and about 400 times farther away, so the two look almost the same size in the sky. But the Moon's umbra barely reaches the Earth: it is at most about 270 km wide and usually far less, sweeping a thin strip across the surface. On average, any given spot on Earth sees a total solar eclipse only about once every 375 years. A lunar eclipse, on the other hand, is seen from the whole night side of the planet, so any city sees many more lunar eclipses than total solar ones.

How to watch an eclipse safely

How we calculate

Everything is computed on the server, with no external data: the Sun from a truncated VSOP87 series, the Moon from the 60+60-term series of Meeus (Astronomical Algorithms, ch. 47), eclipse detection from the Meeus chapter 54 criteria and the exact moment of greatest eclipse found numerically from the position of the shadow axis. For each Brazilian capital, the visibility of a solar eclipse comes from the real separation between the centers of the Sun and the Moon as seen from the city (with parallax), and the obscuration is the overlap area of the two disks. For lunar eclipses we check the altitude of the Moon, from the observer's viewpoint, at each phase.

How accurate is it? We checked all 22 solar and 23 lunar eclipses of 2026–2035 against the NASA eclipse catalogs: the type is the same in every case, the time of greatest eclipse differs by at most about 16 seconds, gamma by at most 0.001 and the magnitude by at most 0.002. For the local solar circumstances we compared Manaus, Belém and Rio de Janeiro with published values: the covered share of the Sun agrees to within 0.2 percentage points. Times on this page are rounded to the minute and use an estimated ΔT (difference between uniform time and UT) of about 69 seconds. Terrain, buildings, clouds and the exact spot in the city are not considered, and this page does not draw the path of totality: it is an approximation, so use official sources for that.

Brasília time is UTC-3 all year, since Brazil no longer uses daylight saving time. Capitals in Amazonas, Mato Grosso, Mato Grosso do Sul, Rondônia and Roraima are on UTC-4 and Acre is on UTC-5, so their local clock times in the tables differ from Brasília.
