The line you stopped holding
Pisces full moons show where you have dissolved into someone else's situation — the favour that became a role, the empathy that became responsibility. Exhaustion arrives before the explanation does. What is asked is not that you care less but that you locate, specifically, the point at which your involvement stopped helping and started substituting.

Meet someone halfway on purpose
Libra new moons open a partnership — a new one, or a deliberate reset of an existing one. The intention that works here is mutual and stated out loud rather than privately hoped for. Libra's trap is starting something agreeable that you have not actually agreed to; name the terms while the moon is still dark.

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 22° Pisces 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 2027'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.
