September 2026 Astrology Calendar: Every Transit, Date and Time

September 2026 moves from Virgo’s practical focus to Libra’s search for balance. It starts with a hard Mars–Saturn square, brings the Virgo New Moon and the equinox, and ends with Mars entering Leo. All times below are UTC, calculated with the Swiss Ephemeris; the table above converts them to your local time.

The big picture for September 2026

The month is about adjusting systems before the busy autumn. Mars in Cancer squares retrograde Saturn in Aries on the first day, so plans meet resistance and need a steadier pace. Mercury moves fast, from Virgo into Libra on September 10 and into Scorpio on September 30, linking with Pluto, Neptune, Uranus, Saturn and Jupiter along the way.

Behind the scenes the outer planets shift. Uranus turns retrograde on September 10, and Neptune sextiles Pluto on September 16, a long generational aspect that works over years. Venus enters the shadow of its October retrograde around September 1 and moves into Scorpio on September 10, so the relationship and money questions of October start to show early.

Week by week

September 1–9: Mars square Saturn

Mars squares Saturn on September 1 at 09:59 UTC at 13°39′ Cancer and Aries: pressure, delays and the need to choose between speed and safety. Mercury sextiles Mars a few hours later, which helps you talk the obstacle through. The first week rewards steady effort over force.

September 10–16: Venus in Scorpio, Uranus retrograde, the Virgo New Moon

September 10 is dense. Venus enters Scorpio at 08:07 UTC, Mercury enters Libra at 16:21 UTC, and Uranus stations retrograde at 18:27 UTC at 5°41′ Gemini.

The New Moon follows on September 11 at 03:27 UTC at 18°25′ Virgo. It suits intentions about health, routines, work systems and useful skills. Mercury trines Pluto and opposes Neptune on September 12, then trines Uranus on September 14: strong days for research and new ideas, as long as you verify what you hear. The Sun sextiles Mars on September 14. Venus squares Pluto on September 15, intensifying attraction and jealousy. Neptune sextiles Pluto on September 16, both retrograde at 3°16′.

September 17–23: Mercury opposes Saturn, the equinox

Mercury opposes Saturn on September 18, a sober check of plans and agreements. Mercury sextiles Jupiter on September 21, bringing good news and a more optimistic tone. The Sun enters Libra on September 23 at 00:05 UTC: the autumn equinox and the start of Libra season.

September 24–30: the Aries Full Moon and Mars in Leo

On September 26 the Sun opposes Neptune, trines Pluto, and the Full Moon peaks at 16:49 UTC at 3°37′ Aries, highlighting independence, courage and the balance between your needs and a partner’s. Mars enters Leo on September 28, and the Sun trines Uranus that day. Mercury enters Scorpio on September 30, preparing the ground for its retrograde in late October.
