♃ Jupiter Combustion 2026

In 2026 Jupiter is combust from July 17 to August 10, 2026 and meets the Sun on July 29, 2026, at 12:18 UTC, at 6°24′ Leo.

The card has the full timing: when Jupiter enters and leaves the beams, the hours of the cazimi, and how far north or south of the Sun it passes.

Jupiter moves slowly, 0.22° to 0.24° a day at its conjunctions, so the Sun does nearly all the catching up. After one full lap the Sun finds Jupiter about a sign further on and needs 395 to 402 days in all to reach it again. In these years each cazimi falls 30.0° to 36.8° past the previous one, 30 to 38 days later in the year.

The result is a slow walk through the zodiac, one sign per conjunction: Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, Pisces and Aries. The table lists each step.

Ten combustions, one per conjunction. Jupiter barely moves while it is combust, 4.8° to 5.5° from start to end, so every period in these years stays inside one sign.

Jupiter is the greater benefic of traditional astrology, the significator of law, teaching, faith, patrons and generosity. Combust, its help is read as present but out of sight: protection works without being noticed, and judges, sponsors and institutions are slow to act on anyone's behalf. At the cazimi the same benefic is counted at full strength.

Because the combustion comes round about once a year and lasts about three weeks, many astrologers simply mark it as a poor window for anything that needs an institution's good will, such as an appeal, a grant application or a book launch, and a good one for study and preparation.

With 398 days on average between conjunctions, each Jupiter cazimi comes about a month later in the calendar than the last. Sooner or later the date runs past December 31, and that calendar year has no cazimi at all.

In these years it happens to 2031: the cazimi of November 30, 2030 is followed by the one on January 1, 2032. 2031 still has 11 combust days, at the very end of December, because that combustion starts on December 21, 2031.

Jupiter is retrograde for 3.9 to 4 months around each opposition, with Earth lined up between it and the Sun, and combust for 21 to 23 days around each conjunction, on the far side. The cazimi comes 138 to 140 days into each direct stretch, with 133 to 145 days still to go before the next retrograde.

So none of the ten combustions in these years touches a retrograde. Retrograde Jupiter is the planet at its nearest and brightest; combust Jupiter is the planet at its farthest, 6 to 6.5 AU away, and invisible.

Jupiter is combust on 6% of days, 21 to 23 days about once a year, so roughly one person in 17 is born with it. The traditional reading is a benefic working for the native's own standing rather than for others: generosity with strings, faith that is private, luck that arrives through the person's own effort and name. The Sun's sign and house show where.

In the old scheme a birth inside the 18-hour cazimi puts Jupiter at full strength, read as beliefs and identity that coincide.

The birth chart calculator shows how far your Jupiter is from your Sun.

In a year with one whole combustion Jupiter spends 22 to 25 days combust. A year where the combustion straddles New Year shares it with the next, which is why 2031 and 2032 show fewer days.

Jupiter's and the Sun's longitudes come from the site's ephemeris (geocentric, apparent, tropical). A combustion starts when the gap falls below 8°30′ and ends when it rises above it again; under the beams uses 17°, cazimi 17′. Every crossing is found to the second, then recomputed by a separate program as a check. Latitude does not enter the orbs; it is shown as the distance from the Sun's center.

Prose dates are UTC. Times in the cards and tables follow the switch above them. The about page has the method for the whole site.
