Lunar & Solar Eclipse Tracker

Countdown to the next lunar or solar eclipse.

See exactly how many days until the next lunar or solar eclipse, its type (total, partial, annular or penumbral), and where it's visible from. Covers every confirmed eclipse for 2026 and 2027, filterable by solar or lunar, with plain-language diagrams explaining the difference between the two and why a totally eclipsed moon turns red ("blood moon").

Frequently asked questions

When is the next eclipse?

See the live countdown at the top of this page — it shows the very next solar or lunar eclipse, its type and exactly how many days away it is, calculated automatically from today's date.

What is the difference between a solar and lunar eclipse?

In a solar eclipse, the Moon passes between the Sun and Earth, blocking sunlight from a small area of Earth. In a lunar eclipse, Earth passes between the Sun and the Moon, casting its shadow onto the Moon instead. Solar eclipses only happen at a new moon; lunar eclipses only happen at a full moon.

What causes a blood moon?

A "blood moon" is a total lunar eclipse. Even fully inside Earth's shadow, the Moon isn't completely dark — sunlight bending through Earth's atmosphere reaches it, with the atmosphere filtering out blue light (the same effect that makes sunsets red), leaving only reddish light to illuminate the Moon.

What is a total, partial, annular and penumbral eclipse?

A total eclipse fully covers the Sun (solar) or Moon (lunar). A partial eclipse only covers part of it. An annular solar eclipse happens when the Moon is too far from Earth to fully cover the Sun, leaving a visible "ring of fire." A penumbral lunar eclipse is a subtle shading as the Moon passes through Earth's outer, lighter shadow.

Why isn't there a solar and lunar eclipse every month?

The Moon's orbit is tilted about 5 degrees relative to Earth's orbit around the Sun. Most months, the new or full moon passes above or below the alignment needed for an eclipse — it only lines up closely enough a few times a year.

Is it safe to look at a lunar eclipse?

Yes — a lunar eclipse is completely safe to view with the naked eye, since you're just looking at moonlight, the same as any other night. A solar eclipse is different: it requires certified eclipse glasses or proper filters, except during the brief moment of total coverage.

How often do total solar eclipses happen?

A total solar eclipse happens somewhere on Earth roughly every 18 months on average, but any single location only sees one about once every 300-400 years — which is why people often travel to be inside the narrow path of totality.

Is this eclipse tracker free?

Yes — completely free, with no sign-up and no app to install. Every date runs instantly in your browser.
