Together, the systems describe a lively, outspoken personality who enjoys a spirited debate, tells stories with energy and tends to make plain speaking sound like entertainment rather than criticism. On December 3 the Sun usually sits at about 11° Sagittarius, in the second decan, where Mars is the sub-ruler alongside Jupiter. Mars, ruler of Aries, acts as sub-ruler for the middle of Sagittarius, roughly December 2 to December 11. The sign's love of freedom picks up a sharper, more competitive edge. Early-December birthdays are frequently linked with bold, energetic people who are quick to champion a cause, whether on a playing field, in a debate or on the road. Their honesty may be direct enough to startle. Mars brings drive and courage, along with impatience when life moves slowly. Channelled well, this mix of vision and nerve makes for a natural pioneer, someone willing to test an idea in the real world. ## December 3 in numerology Born on the 3rd, you carry a birthday number of 3 in its simplest form. As a supporting number, the day of birth is read as a gift that shows in everyday style rather than in the larger direction of a life. The single-digit 3 is traditionally associated with expression: talking, writing, making things, finding the joke in a heavy afternoon. Its energy is light and spontaneous, often called youthful whatever the person's age. Numerologists tend to suggest that 3s benefit from finishing what they begin, because their ideas are worth more completed than merely sketched in a notebook. The Life Path, the main number in a numerology chart, also uses the birth year, so it changes from one December 3 birthday to the next: it is 4 for 1960, 5 for 1970, 6 for 1980 and 7 for 1990, for example. Some birth years on this date reach the master number 11. ## Born on December 3: season, famous birthdays and Chinese zodiac December birthdays arrive at the start of northern winter, around the shortest days and the year's festivities, and at the start of summer in the southern hemisphere. Sagittarius holds most of the month, with Capricorn beginning around December 21 or 22. In numerology December is month 12, which reduces to 3: expression and sociability, built from the 1 and 2 of initiative and partnership. December 3 is the 337th day of the year (338th in a leap year). By December 22, 19 days later, the Sun has usually moved on into Capricorn. For the Chinese zodiac, Lunar New Year has always passed by December 3, so the animal is simply the one for the birth year. Well-known people born on December 3 include Joseph Conrad (1857), Julianne Moore (1960) and Ozzy Osbourne (1948). ## Frequently asked questions ### What zodiac sign is December 3?
