One habit, honestly measured
A Virgo new moon is for the unglamorous fix: the routine, the health question you have been postponing, the process that would save an hour a week for the rest of your life. Pick one and make it measurable. Virgo intentions fail when they are aspirational and hold when they are specific enough to tick off.

Impatience arrives as clarity
A full moon in Aries lights up whatever you have been waiting politely for. The Libra sun keeps asking what is fair to everyone; the Aries moon stops asking. What surfaces is rarely new information — it is the point at which the cost of staying agreeable finally outweighs the cost of saying the blunt thing. Decisions made now tend to hold, though the delivery is worth sleeping on.

How these dates were calculated
A new moon is the instant the Moon and Sun share the same ecliptic longitude; a full moon is the instant they sit exactly opposite. Both are single moments rather than nights, and both are computed here directly from the Swiss Ephemeris — the engine professional astrology software runs on — then localized to US Eastern Time. Nothing on this page is copied from another calendar.
The degree matters more than the phase. A full moon at 3° Aries activates whatever sits near that degree in your own chart, which is why one lunation flattens one person and passes another entirely. To find out which of your placements September 2026's moons touch, cast your free natal chart and compare the degrees, then read your monthly horoscope for the wider context.
That was the sky. This is your sky.
Everything above is true for everyone. These three are true only for you — and all free.
