2nd decan of Sagittarius: Moon
Each sign is divided into three decans, 10° slices that the Sun crosses in about ten days each. December 2 falls in the second decan of Sagittarius (about December 2–11), which the traditional Chaldean system assigns to Moon. Astrologers say that adds sensitivity, intuition and emotional depth.
The Moon adds a tidal, feeling-led quality, so moods, memory and the need for a safe emotional home matter more than the sign alone would suggest.
The number 2 in numerology
The 2 is the number of partnership. A birthday on the 2nd is read in numerology as diplomatic, cooperative and tuned in to what other people need.
Numerology is a separate tradition from astrology and is offered here for interest.
December birthstone and flower

Sagittarius love and compatibility
Sagittarius wants a partner who is also a travel companion — in the literal and intellectual sense. Shared adventures, big conversations and plenty of laughter matter more to them than routine romance.

What zodiac sign is December 2?
December 2 falls in Sagittarius, which runs from November 22 to December 21 in the tropical zodiac. The Sun changes sign at a slightly different moment each year, so the boundary can fall a day or so either side of these dates. If you were born close to the edge, your birth year, time and place decide it.
Is December 2 a cusp birthday?
Not by the usual definition, which counts the first and last couple of days of a sign. December 2 is day 11 of Sagittarius season, so it is normally read as a clear Sagittarius birthday.
Which decan is December 2?
December 2 is in the second decan of Sagittarius (December 2–11). In the traditional Chaldean system this decan is ruled by Moon, which astrologers say adds its own flavour to Sagittarius. Some modern astrologers assign decan rulers by element instead, which gives different planets, and decans are strictly 10° slices of the zodiac, so the date range is approximate.
What are the birthstone and flower for December?
The modern birthstone for December is Turquoise and the birth flower is the narcissus. These come from calendar tradition rather than astrology, and the lists vary by country and source.
