New Moon December 9, 2026 at 16° Sagittarius, exact at 00:51 UTC. Free calculator maps it into your birth chart: natal house and aspects to your personal planets, from the Swiss Ephemeris.
In Sagittarius, astrologers read a new moon through wider horizons: study, travel, belief, and the honest question of what is true for you. Sign themes are the shared weather, the part every horoscope column can tell you. What no column can tell you is the house: the same 16° Sagittarius new moon lands in a different life area for every birth time, and that placement is where astrologers hang the personal reading. The calculator above computes yours exactly.
This page tracks the new moon of December 9, 2026, exact at 00:51 UTC at 16° Sagittarius. The instant is solved from the Swiss Ephemeris at the true Sun–Moon geometry rather than quoted from a printed calendar; the Moon's longitude at that instant is then placed into your natal houses and checked against your personal planets with tight orbs. A new moon that makes no close contact with your chart is an honest result too: astrologers would call that one background weather for you.
Astrologers pair the December 9, 2026 new moon with the full moon of December 24, 2026: one arc's opening and culmination, a bit over two weeks apart. Reading the pair as one story, through the house each end touches in your chart, is how astrologers track a cycle rather than a single night.
The new moon is exact at 00:51 UTC on December 9, 2026, at 16° Sagittarius. The instant is solved from the Swiss Ephemeris at the exact Sun–Moon conjunction, not copied from a table, and the calculator above places that degree into your own natal houses.
Astrologers read a Sagittarius new moon through wider horizons: study, travel, belief, and the honest question of what is true for you. That is the sign-level weather; the personal layer is the house. Enter your birth details above and the calculator shows which of your twelve houses holds 16° Sagittarius for you.
Enter your birth date, time and place. The calculator computes your natal house cusps with the Swiss Ephemeris and places 16° Sagittarius into one of your twelve houses. Birth time matters here: house cusps shift roughly every four minutes of clock time.
Tradition reads the new moon as the seeding beat of the lunar cycle: the Sun and Moon meet, the sky goes dark, and what begins quietly builds toward the following full moon. Tradition pairs this one with the full moon of December 24, 2026 as the opening and culmination points of a single arc. The house this new moon lands in for your chart is where astrologers would place that seeding.
