Sky calendar
The next 18 months of things that happen on a date, solved from the ephemeris rather than kept in a list. Almost every one is the same instant for everybody on Earth, so a date here needs no location to be true — what is visible tonight is the list that does depend on where you are standing.
Coming up
] SOONEST FIRST- ECLIPSEIN 12 HOURS28FRI
Partial lunar eclipse
Earth's shadow takes a 97% bite out of the full Moon.
- ECLIPSEIN 162 DAYS6SAT
Annular solar eclipse
A ring of Sun stays visible around the Moon, greatest over 31.3°S, 48.5°W.
- ECLIPSEIN 177 DAYS20SAT
Penumbral lunar eclipse
A faint, even dimming as the Moon crosses the outer edge of Earth's shadow.
+WHAT THE EIGHT KINDS ARE
- Eclipses — solar and lunar, with where on Earth each is greatest.
- Meteor showers — dated by where the Earth is in its orbit, not by a fixed calendar day.
- Moon phases — the four quarters, which set what else is worth chasing that fortnight.
- Close pairings — two bright things within a few degrees of each other.
- Oppositions — the night each outer planet is closest, biggest and up all night.
- Elongations — the mornings and evenings Mercury and Venus stand furthest from the Sun.
- Equinoxes and solstices — the four turning points of the year.
- Flybys — near-Earth asteroids passing inside twenty lunar distances.
Pick a place and every event will say which hours are worth being outside for it. Until you do, nothing here is answered for anywhere in particular.
August 2026
] 1 EVENT- 28FRIECLIPSE--:--
Partial lunar eclipse
Earth's shadow crosses 97% of the Moon's disc at the deepest point, over about 199 minutes — a clean curved bite out of a full moon, obvious to the naked eye and to a phone camera. Visible from wherever the Moon is above the horizon at the time.
+WHAT TO EXPECTCLOSE
- COVERED
- 97% — of the disc, at the point where the eclipse is greatest
- DEEPEST PHASE
- 199 min
Nothing needed at all: a lunar eclipse is safe to watch with your eyes, and binoculars mostly add colour. It is slow — over an hour from first shadow to deepest — so it rewards going out more than once rather than standing outside for the whole of it.
February 2027
] 2 EVENTS- 6SATECLIPSE--:--
Annular solar eclipse
The Moon passes centrally across the Sun but is too far from Earth to cover it, so at greatest eclipse — over 31.3°S, 48.5°W — a ring of Sun stays visible all the way round it, with 86% of the disc covered. It never gets dark and it is never safe to look at without a certified solar filter.
+WHAT TO EXPECTCLOSE
- COVERED
- 86% — of the disc, at the point where the eclipse is greatest
- GREATEST OVER
- 31.3°S, 48.5°W — where the Moon's shadow passes closest to the centre of the Earth
Never with an unaided eye, and never through binoculars or a telescope without a filter made for the job — a moment of it does permanent damage. Certified eclipse glasses for looking, or a pinhole in a card projecting onto a second card, which costs nothing and is safe for a crowd.
- 20SATECLIPSE--:--
Penumbral lunar eclipse
The Moon passes through the soft outer edge of Earth's shadow, not the dark core of it. The whole disc dims slightly and unevenly — enough to notice in a photograph taken before and after, and easy to miss by eye.
+WHAT TO EXPECTCLOSE
Nothing needed at all: a lunar eclipse is safe to watch with your eyes, and binoculars mostly add colour. It is slow — over an hour from first shadow to deepest — so it rewards going out more than once rather than standing outside for the whole of it.

August 2027
] 2 EVENTS- 2MONECLIPSE--:--
Total solar eclipse
The Moon covers the Sun completely along a narrow track across the Earth, and takes a bite out of it for a wide margin either side. Greatest eclipse falls over 25.5°N, 33.2°E — being on that track is the whole difference between a total eclipse and a partial one, and this page does not know where you are standing. Never look at any phase of it without a certified solar filter.
+WHAT TO EXPECTCLOSE
- COVERED
- 100% — of the disc, at the point where the eclipse is greatest
- GREATEST OVER
- 25.5°N, 33.2°E — where the Moon's shadow passes closest to the centre of the Earth

8 events for the 18 months from today, of the kinds selected above. Times are instants, shown on your own clock; how every number here was made.
Nothing here is a hand-kept list. Every date except the flybys is solved from the same ephemeris the rest of the site uses to place the planets, at the moment you load the page; a meteor shower is dated by the longitude the Sun reaches rather than by a day of the month, which is why its date moves a little from year to year. The same events are available as JSON and CSV.
The 26 close approaches come from NASA/JPL Center for Near-Earth Object Studies, as they stood on 2026-08-25, and cover passes inside 20 lunar distances through 2028-03-27. Unlike everything else on this page they cannot be computed from an ephemeris here — a newly discovered asteroid has no orbit until somebody measures one — so they are as complete as that date and no more.
