When Is the Next Blood Moon? Dates and Meaning
Most pages that answer this question are answering it about a year that has already gone.
So, as things stand: when is the next blood moon? 31 December 2028. A total lunar eclipse, greatest near 16:52 Universal Time, with one hour and eleven minutes of totality, visible from Europe, Africa, Asia, Australia and the Pacific. Nothing before it qualifies. The last total was 3 March 2026, and the six eclipses in between are all of other kinds.
The deepest of the six, and where most searches for blood moon 2026 dates go wrong, is the partial of 28 August 2026 — ninety-three per cent of the moon's diameter inside Earth's dark shadow, a bright sliver left outside. That sliver is the whole difference.
A thousand and thirty-four days between one total and the next. That gap is the most useful thing on this page, because almost nobody mentions it.
When is the next blood moon — and why 2027 doesn't have one
A blood moon is a total lunar eclipse: the whole moon inside the deep cone of Earth's shadow, lit only by sunlight bent through the rim of our atmosphere. Partial and penumbral eclipses are the same event, less of it.
Astronomers measure the difference with umbral magnitude — the fraction of the moon's diameter swallowed by that dark inner shadow, the umbra. At 1.0 and above the disc is inside it whole and goes copper. Between zero and one, a bite is taken out. Below zero it misses the umbra and crosses only the penumbra, the soft fringe where Earth blocks part of the sun.
Run the next few years through that number. The partial of 28 August 2026 comes in at 0.930, the deepest shadow the moon enters until 31 December 2028 itself. Then 2027 offers three eclipses at −0.057, −1.068 and −0.525. All negative. Not one touches the umbra.
So the answer to searches for no lunar eclipse in 2027 is: there are three, and none is a blood moon. Two barely count as sights — 18 July merely grazes the fringe, 17 August shades half the disc weakly, a photograph's job rather than an eye's. But 20 February is worth marking. The moon misses the umbra by six hundredths of its own width, so nearly the whole disc sits in deep penumbra and one limb goes visibly dusky. Not copper. Not nothing either.
Every lunar eclipse from here to 2030
Dates, types and magnitudes from NASA's decade catalogue, its visibility wording kept as printed. That last column is not a narrow path — just where the moon is above the horizon.
| Date | Type | Umbral mag. | Totality | Where the moon is up |
|---|---|---|---|---|
| 28 Aug 2026 | Partial | 0.930 | — | E Pacific, Americas, Europe, Africa |
| 20 Feb 2027 | Penumbral | −0.057 | — | Americas, Europe, Africa, Asia |
| 18 Jul 2027 | Penumbral | −1.068 | — | E Africa, Asia, Australia, Pacific |
| 17 Aug 2027 | Penumbral | −0.525 | — | Pacific, Americas |
| 12 Jan 2028 | Partial | 0.066 | — | Americas, Europe, Africa |
| 6 Jul 2028 | Partial | 0.389 | — | Europe, Africa, Asia, Australia |
| 31 Dec 2028 | Total | 1.246 | 1h 11m | Europe, Africa, Asia, Australia, Pacific |
| 26 Jun 2029 | Total | 1.844 | 1h 42m | Americas, Europe, Africa, Middle East |

Clock times here are Universal Time. NASA prints its own in Terrestrial Dynamical Time, about a minute ahead this decade.
Note the shape of the totals. Across 2021–2030 NASA lists twenty-two lunar eclipses, nine of them total — one roughly every thirteen months, though the five-millennium average is nearer seven a decade. And they never arrive on the average. Six fell between May 2021 and March 2026, then nothing for almost three years, then three inside a single twelve-month stretch.
Six, then nothing, then three. That clumping has a cause.
The moon's orbit is inclined roughly five degrees to Earth's and cuts that plane at just two points, so an eclipse is possible only near one of those crossings — a few weeks, twice a year. How close the full moon comes to the dead centre of the shadow inside that window creeps season by season, like the hand of a slow clock. Years of tight aim give totals. Then it loosens, and you get 2027.
Will you actually see it?
Here is what most people get backwards from solar eclipses. A total solar eclipse paints a shadow track a hundred miles wide and you either stand in it or you don't. A lunar eclipse has no track.
Not a path. A hemisphere.
The moon enters Earth's shadow and is eclipsed for everyone at once, and the only question is whether it is above your horizon then. A "total lunar eclipse visibility map" is really a night map — the half of the planet turned from the sun.
Greatest eclipse on 31 December 2028 falls near 16:52 UT, putting the moon overhead close to 108° east. Best seats: Southeast Asia and western Australia, well after dark. Europe and Africa catch it low in the east near moonrise. The Americas miss it entirely — daylight, moon below the horizon.
26 June 2029 is the one to plan around. Magnitude 1.844 is a deep central passage, and its hour and forty-two minutes of totality is about as long as this century gets. Greatest eclipse near 03:22 UT puts the moon over the western Atlantic — late evening in the eastern Americas, the small hours for Europe, Africa and the Middle East.
No filters, no equipment, no eye risk. You walk outside and look up. Why the shadowed moon goes copper rather than black is worked through in what a blood moon means in the Bible, and the solar side is solar eclipse in the Bible.
The sacred date each blood moon falls on
This is the column astronomy sites never carry. Day 4 counts a 364-day sacred year — fifty-two weeks exactly, four seasons of ninety-one days, anchored to the March equinox and labelled Anno Mundi. Enoch's Astronomical Book, Jubilees and the Dead Sea Scrolls all preserve a year of that shape, though whether it was ever the Temple's own is a question scholars still weigh and Day 4 does not claim to settle. Laid over the eclipse dates:
| Eclipse | Sacred year | Counted day | Hebrew date |
|---|---|---|---|
| 28 Aug 2026 (partial) | AM 6026 | day 162 — 71st of the second season | 15 Elul 5786 |
| 31 Dec 2028 (total) | AM 6028 | day 288 — 15th of the fourth season | 13 Tevet 5789 |
| 26 Jun 2029 (total) | AM 6029 | day 99 — 8th of the second season | 13 Tammuz 5789 |
| 20 Dec 2029 (total) | AM 6029 | day 276 — 3rd of the fourth season | 14 Tevet 5790 |
Two honest footnotes. First, sunset. The Hebrew day turns at dusk, so a daytime conversion is not always the date you would be standing in. Both December eclipses land after dark wherever they are visible, so by then the reckoning has moved on — to 14 Tevet and 15 Tevet.
Second, read down the Hebrew column: the 15th, the 13th, the 13th, the 14th. A Hebrew date is a phase reading as much as a label — the month opens at the new moon, so the number says how far round the cycle you have come, and the mid-teens is where the moon is round. Only a full moon can be eclipsed, so mid-month is the one place an eclipse has ever landed, and a blood moon near a mid-month feast tells you nothing the arithmetic had not already promised. Tetrad claims come apart on that in what a blood moon means in the Bible.
None of the four is a Sabbath — those sit on year-days 4, 11, 18 and on to 361. Three do land on the week's day 4, the slot the sacred year itself opens on. Arithmetic, not a message. Whether any falls near an appointed time is a separate lookup, kept in the biblical feast days calendar.
Day 4's Calendar screen sets the everyday and sacred dates side by side with feasts marked, though travelling that timeline to any year you like belongs to the subscription, not the free tier. It predicts no eclipses, computes no visibility, works out no sunset times. Every figure here came from a catalogue, not the app.
Does it mean anything?
Straight answer: no biblical text describes a lunar eclipse, and none attaches a meaning to one. Joel's darkened sun and bloodied moon are prophetic judgment language about collapsing skies, and reading that as an eclipse timetable is a move that arrived centuries after the prophets did — though Christians land in different places on how much of Joel is still ahead. The lights were hung "for signs, and for seasons, and for days, and years" — Genesis 1:14 — and a thing predictable to the minute for a thousand years makes a very odd warning. The lights that keep time works through the difference between watching and decoding.
Common questions
When is the next total lunar eclipse and will I see it?
31 December 2028, greatest near 16:52 UT, with 1h 11m of totality. The moon is up for Europe, Africa, Asia, Australia and the Pacific, best placed for Southeast Asia and western Australia. The Americas miss this one but get 26 June 2029.
How often do blood moons happen?
About one every thirteen months this decade — nine total lunar eclipses across 2021–2030 — though the five-millennium rate is closer to seven a decade. Either way, they arrive in clusters rather than on the average: six between May 2021 and March 2026, then nothing for almost three years, then three in the twelve months from December 2028.
What Hebrew or sacred calendar date does the eclipse fall on?
For 31 December 2028: day 288 of the 364-day sacred year AM 6028 — the 15th day of the fourth season — and 13 Tevet 5789, turning to 14 Tevet at sunset, before the shadow arrives. Expect a mid-month number every time: the Hebrew month runs from the new moon, and only a full moon can be eclipsed.
Does it mean anything?
No biblical text describes a lunar eclipse or tells anyone to watch for one. The sky-darkening oracles in Joel, Isaiah, Ezekiel and Amos are judgment language about empires and the day of the LORD, not observing reports. An eclipse is orbital geometry, printable centuries ahead.
What the gap is for
A thousand and thirty-four days stand between 3 March 2026 and 31 December 2028. Against a shadow that has kept this appointment since long before anybody was writing dates down, that is not a drought. It is just the interval, computed centuries ahead.
Which is the quiet argument under this page. The sky is not sending anything. It is keeping time — poorly suited to warnings, exactly suited to being counted. And the counting does not stop in the blank years. Almost every one of those days carries a number, a season, a place in the week. The exceptions are deliberate: after day 364 the count halts for a day or two, the Waiting Space, until the March equinox re-pins day one.
Day 4 will not tell you when the moon goes dark. It will tell you, free and without an account on any platform, what sacred day you are standing in — on the night the shadow comes, and on every ordinary night between here and there.
