In numerology the day gives birthday number 3. The Life Path also uses the birth year. Capricorn is cardinal and earth. ## Key facts | Fact | Value | | --- | --- | | Sun sign | Capricorn in every year from 1930 to 2030 | | Decan | Capricorn decan 1 (Saturn) or Capricorn decan 2 (Venus) | | Sun's position at noon UTC | About 8° Capricorn | | Capricorn · element · modality · ruler | Earth · Cardinal · Saturn | | Birthday number | 30 → 3 | | Life Path by birth year | 1960: 4 · 1970: 5 · 1980: 6 · 1990: 7 · 2000: 8 · 2010: 9 · 2020: 1 | | Chinese zodiac | After Lunar New Year, so the animal is the birth year's own | | Born on this day | LeBron James (1984), Kersti Kaljulaid (1969), Tiger Woods (1975) | ## December 30 zodiac sign and personality December 30 reduces to 3, bringing humour and expressiveness to a sober early-Capricorn Sun at about eight degrees. Saturn, ruling both sign and decan, encourages restraint, so the wit tends to be dry rather than loud. Interpretively, this is the deadpan observer at the end-of-year party, whose understated remarks are quoted for weeks afterwards. On December 30 the Sun usually sits at about 8° Capricorn, in the first decan, where Saturn rules the decan as well as the sign. Saturn rules Capricorn and also governs the sign's first decan, which spans roughly December 22 to December 31. Birthdays here arrive at the turning point of the year, and this decan is traditionally read as the sign in its most concentrated form: patient, ambitious, realistic and willing to climb slowly. Responsibility often arrives early in life for these natives. Doubled Saturn can make them hard on themselves and reluctant to rest until the work is complete. Their quiet authority tends to grow with age, and humour, usually dry, is one of the ways they lighten what they carry. ## December 30 in numerology A birthday on the 30th reduces as 3 + 0 = 3. The 0 is often read as amplifying the 3, so this birthday number carries an extra dose of expression, imagination and social energy. Unlike the 12th or 21st, the compound contains only the 3 itself, which numerologists sometimes describe as creativity without dilution. Thirtieth-born people are frequently described as eloquent, entertaining and quick with ideas. As a secondary number, the 30 tends to shine in writing, speaking or performance. Focus is their usual challenge, since so many ideas compete for attention. The Life Path, the main number in a numerology chart, also uses the birth year, so it changes from one December 30 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 30: 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 30 is the 364th day of the year (365th in a leap year). By January 21, 22 days later, the Sun has usually moved on into Aquarius. For the Chinese zodiac, Lunar New Year has always passed by December 30, so the animal is simply the one for the birth year. Well-known people born on December 30 include LeBron James (1984), Kersti Kaljulaid (1969) and Tiger Woods (1975). ## Frequently asked questions ### What zodiac sign is December 30?
