Two true things at once
A Gemini full moon pulls the second half of a story into view — the message you did not send, the version of events you skipped. Expect to hold two contradictory accounts and find both defensible. The pressure is to resolve that quickly. Resist it; Gemini's gift here is tolerating the contradiction long enough to notice which half you have been protecting.

Name the ten-year version
A Capricorn new moon builds slowly and finishes. This is the moon for the goal with a structure under it: the qualification, the business, the debt with an end date. Set something you can still see the shape of in a decade, then define the first quarter of it. Capricorn does not need motivation; it needs a schedule.

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 21° Gemini 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 December 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.
