Halloween 2026: no full moon, two retrogrades

Halloween is a night you spend on doorsteps. Everyone else's doorsteps. Then you come home, peel off the face paint, and something softens: the house smells of candle wax, somebody is sorting candy on the floor by brand, and you're suddenly thinking about the Halloweens you had as a kid.

The Moon agrees with the mood. At 8 pm EDT, 31 October 2026 (00:00 UTC, 1 November) it sits at 27°28′ Cancer. Astrologers read Cancer as the sign of home, family, food and memory. A waning Moon, in the same tradition, is a time for letting go and looking back rather than starting fresh. For a night tied up with remembering the dead, that's a tidy match, if you like your symbols to rhyme. Treat it as a mirror to think with, not a forecast.

One practical note. The Moon is late in Cancer, about 2.5° from the end, and at its average pace it crosses into Leo roughly 5 hours later. That means on the US West Coast the Moon may already be in Leo by the end of the evening. Check your own time and place with the moon sign calculator. A Moon this late in a sign is often void of course, too; the void-of-course tool shows the exact window.

Every October someone at a party, usually holding a cider, says Halloween is "really" an ancient Celtic festival. They're half right, and the other half is more interesting.

Halloween is often traced to Samhain, a Gaelic festival that marked the end of the harvest and the start of winter. The Library of Congress describes the popular account: people believed spirits walked the earth, lit bonfires and wore disguises. It also notes that in the 8th century Pope Gregory III set November 1 as a time to honor saints. The evening before became All Hallows' Eve, later Halloween.

How direct the link is remains debated. The Wikipedia article on Halloween sets out both views: some historians see Samhain customs carried into Halloween, others see it starting as the Christian vigil of All Hallows' Day. Samhain itself is first mentioned in Irish literature from the 9th century and was not described in detail until much later, as the Wikipedia article on Samhain explains. So the details of older practice are uncertain, and anyone who sounds very sure is filling in gaps.

Samhain also has a date in the sky: the point halfway between the September equinox and the December solstice. In 2026 the Sun reaches it, at 15°00′ Scorpio, on Nov 7, 2026, 6 days after Halloween night. Some modern pagans keep the festival on that astronomical date, as the Wheel of the Year article notes; the eight-festival wheel itself dates from the mid-20th century. More on the Samhain 2026 page.
