December 15 birthday personality
Saturn rules the last face of Sagittarius in the Chaldean scheme while Leo lends the Sun’s confidence, so belief is read here as conviction that has been tested: the teacher, the elder, the one whose principles have cost them something. Tradition warns against a certainty that stops listening.
Born on the 15th, your 1 and 5 add to 6: independence and movement turning toward care. Numerology reads it as a warm, sociable birthday with a strong pull toward home. With fire, the 6 is read as generous loyalty, the friend who throws the party for you and fights your corner afterwards.
A question to carry from December 15: where is your hope needed at home, and where is it being given away too easily?
The Sun in Sagittarius and the number 6 are only part of the story: your Moon, your rising sign and the rest of your chart have as much to say, and the tradition offers all this as a mirror, never a verdict.
Birthday number 6
Born on the 15th, 1 + 5 = 6, so your birthday number is 6: a 6 vibration supports love, responsibility, beauty, family, and service, with care, beauty, and responsibility as its gift and over-giving, perfectionism, or control through care as its strain.
Your 2027 numbers
For a birthday on December 15 the house method reduces the birth month and the day on their own and adds the Universal Year of 2027, 11 (2 + 0 + 2 + 7 = 11, a master number kept whole), as it stands: December, the 12th month, reduces to 3, the 15th reduces to 6, and 3 + 6 + 11 = 20, which reduces to 2, so 2027 is your Personal Year 2.
A Personal Year 2 is read as a year of patience and partnership, when things grow out of sight and timing matters more than force. With 2027 a Universal Year 11, whose base is also 2, the tradition reads it as doubly a year for listening and for the right alliances.
Personal Months of 2027, a Personal Year 2: Jan 3 Feb 4 Mar 5 Apr 6 May 7 Jun 8 Jul 9 Aug 1 Sep 11 Oct 3 Nov 4 Dec 5
In 2027 December 15 falls on a Wednesday, the day the old reckoning gives to Mercury, and is a Personal Day 2 (5 + 15 = 20, then 2) in a Personal Month 5 (2 + 12 = 14, then 5), while September is a master month 11; the Personal Year itself turns on 1 January, not on the birthday.
December birthstone and birth flower
- Birthstones
- Turquoise, tanzanite and zircon
- Birth flowers
- Narcissus, and holly as the second flower
December’s turquoise, tanzanite and zircon come from the modern list (the Jewelers of America list of 1912, as since revised), and its narcissus and holly from The Old Farmer’s Almanac.
