Astrological calendar

December 2025

Every New and Full Moon, every eclipse with its Saros family, every retrograde and every sign change — in Brasília time, computed with precision ephemerides validated against NASA’s catalogue.

  1. 4 Thursday

    Full Moon in Gemini

    08:14 PM · Brasília time

    Sun and Moon on opposite sides of the sky: maximum light on what had been growing. What was implicit becomes visible — in feeling, in outcome, in conversation.

  2. 10 Wednesday

    Neptune stations direct in Pisces

    09:00 AM · Brasília time

    The planet stations and returns to direct motion: what was under review starts moving again, now with what was learned along the way.

  3. 11 Thursday

    Last Quarter in Virgo

    05:52 PM · Brasília time

    The light wanes: time to harvest what served and release what did not. A conscious closing before the next cycle.

    Mercury enters Sagittarius

    07:39 PM · Brasília time

    A planet changes sign: the same function starts operating in another style. The theme does not change — the manner does.

  4. 15 Monday

    Mars enters Capricorn

    04:33 AM · Brasília time

    A planet changes sign: the same function starts operating in another style. The theme does not change — the manner does.

  5. 19 Friday

    New Moon in Sagittarius

    10:44 PM · Brasília time

    Sun and Moon meet at the same degree: one cycle closes and another begins in the dark. The classic moment to plant intention — not to harvest results.

  6. 21 Sunday

    Sun enters Capricorn

    12:02 PM · Brasília time

    A planet changes sign: the same function starts operating in another style. The theme does not change — the manner does.

  7. 24 Wednesday

    Venus enters Capricorn

    01:25 PM · Brasília time

    A planet changes sign: the same function starts operating in another style. The theme does not change — the manner does.

  8. 27 Saturday

    First Quarter in Aries

    04:10 PM · Brasília time

    A week after the seed, the first tension: what was planted meets the real world. It is a course correction, not a surrender.

What this means for your chart

The calendar is the same for everyone; the effect is not. Each event lands in a different house of your chart — and that is what changes what it asks of you.
