Lunar Calendar September 2026: Every Moon Phase, Exact Time and the Harvest Moon in Aries

The lunar calendar for September 2026 holds four exact phases, one Harvest Moon, and no eclipses at all. After the drama of August, that last part matters more than it sounds.

August opened with an eclipse season that asked a great deal of everyone. September does not. It gives you a clean lunation, an equinox almost exactly in the middle of it, and a full moon in Aries that behaves like a starting pistol rather than a reckoning. If you have been waiting to begin something, this is the month the sky stops interrupting you.

Every time below is the exact moment of the phase, in UTC first, then the zones most of you write to me from.

Lunar Calendar September 2026: Every Phase and Exact Time

Last Quarter, Friday 4 September. 07:51 UTC. 03:51 EDT, 08:51 BST, 01:51 Mexico City, 15:51 Bali. The moon sits in Gemini. This is the release point of the lunation that began in August, and it asks one question: what are you still carrying that you agreed to a month ago and no longer want?

New Moon, Friday 11 September. 03:26 UTC. That is 23:26 on Thursday 10 September in New York, 04:26 BST, 21:26 on Thursday in Mexico City, 11:26 in Bali. Sun and moon both at eighteen degrees of Virgo.

First Quarter, Friday 18 September. 20:43 UTC. 16:43 EDT, 21:43 BST, 14:43 Mexico City, and 04:43 on Saturday 19 September in Bali. The moon is at the very end of Sagittarius.

Full Moon, Saturday 26 September. 16:48 UTC. 12:48 EDT, 17:48 BST, 10:48 Mexico City, and 00:48 on Sunday 27 September in Bali. The moon is at three degrees of Aries, opposite a Sun at three degrees of Libra. This is the Harvest Moon.

Track these against last month and the change in rhythm is obvious. Our moon phases for August 2026 were shaped entirely around two eclipses. September is simply a month.

The Harvest Moon on 26 September, and Why It Is in Aries

A Harvest Moon is not a poetic label. It is the full moon that falls closest to the September equinox, and in 2026 that equinox lands on 23 September at 00:05 UTC. The 26 September full moon is three days later. The August full moon was almost four weeks before it. So the September moon takes the name.

What makes this one unusual is the sign. 2026 gives us Aries at three degrees, about as raw and unhesitating as a full moon gets. Aries does not review. Aries begins. Sitting opposite a Libra Sun that wants everything agreed upon first, the tension is obvious: one half of you wants consensus, the other half has already walked out the door.

Full moons show what is finished. This one will show where you have been asking permission.

The New Moon in Virgo on 11 September

Eighteen degrees of Virgo is a practical, unglamorous, extremely useful place for a new moon. Virgo does not want your vision board. Virgo wants the first small repeatable action, done properly, on a Tuesday, when nobody is watching.

This is the strongest intention setting point in the September 2026 lunar calendar, and the least dramatic. Choose something boring and specific. A scalp oil three nights a week. Ten minutes of reading before the phone. Virgo new moons reward the woman who picks one thing and does it fifteen times, not the woman who picks fifteen things.

Waxing and Waning Windows in the September 2026 Lunar Calendar

Most of what people want from a lunar calendar is two answers: when the moon is growing, and when it is shrinking.

Waning, 28 August to 11 September. Energy moving outward and down. Traditionally the window for clearing, cutting back, finishing, editing, and letting go. Good for removing rather than adding.

Waxing, 11 September to 26 September. Energy building. This is the growth half of the month, and it is the window most hair traditions point to for cutting when you want length and thickness back quickly. We go through that in detail in the lunar hair calendar for September 2026, and the broader logic sits in our lunar hair calendar hub.

Waning again, 26 September to 10 October. The next new moon is 10 October at 15:50 UTC, so September closes mid release rather than mid build. Let the last four days be a clearing out.

If you also follow the Chinese almanac rather than the Western lunar tradition, the two systems disagree more often than people expect. Our feng shui haircut calendar for September 2026 maps where they overlap and where they do not.

The Equinox Sits Almost Exactly in the Middle

23 September at 00:05 UTC. Equal light, equal dark, falling twelve days after the new moon and three days before the full moon, about as close to the centre of a lunation as an equinox gets.

That symmetry is worth using. In the northern hemisphere the light starts leaving. Here in Bali it starts returning. Either way the instruction is the same, which is to notice what you want to carry across the line and what you would rather set down before you cross it. If you dress by the sky, the way we lay out in how to dress by moon phase, this is the week the wardrobe changes weight.

Common Questions About the Lunar Calendar in September 2026

What are the moon phases in September 2026? There are four exact phases: last quarter on 4 September at 07:51 UTC, new moon on 11 September at 03:26 UTC, first quarter on 18 September at 20:43 UTC, and full moon on 26 September at 16:48 UTC. The moon waxes from 11 September to 26 September and wanes either side of that window.

When is the full moon in September 2026? Saturday 26 September at 16:48 UTC, which is 12:48 in New York, 17:48 in London, 10:48 in Mexico City, and 00:48 on Sunday 27 September in Bali. It falls at three degrees of Aries.

Is the September 2026 full moon a Harvest Moon? Yes. The Harvest Moon is the full moon nearest the September equinox, and the 26 September full moon falls three days after the equinox on 23 September. That makes it the Harvest Moon for 2026.

When is the new moon in September 2026? Friday 11 September at 03:26 UTC, at eighteen degrees of Virgo. In North America it happens late on Thursday 10 September.

Is there an eclipse in September 2026? No. The eclipse season that opened in August has closed, so September 2026 carries no solar or lunar eclipse. Both lunations this month are ordinary.

What is the best time to cut your hair in September 2026? If you want growth and thickness, most lunar hair traditions point to the waxing half of the month, 11 September to 26 September. If you want to slow growth down or hold a shape, the waning halves are 28 August to 11 September and 26 September to 10 October.

The lunar calendar for September 2026 gives you no eclipses to blame and no drama to wait out. Which means whatever happens this month is actually yours.
