December 11 birthday personality
The Moon takes the middle decan of Sagittarius in the Chaldean order and Aries lends Mars’s dash by triplicity, so tradition reads a restless, warm-hearted optimism here, quick to set out and quick to forgive. The reflection is whether leaving has become easier than staying.
Born on the 11th, you have a master number for a birthday, kept whole by the Almanac’s method: 11, read as intuition and inspiration, with 2 underneath it as its everyday form. Numerology treats it as a sensitive birthday that needs grounding as much as vision. Read through fire, the master 11 is the bright idea that sets others alight, and it asks for rest as much as for an audience.
A question to carry from December 11: what quiet hunch is your hope asking you to test this year?
The Sun in Sagittarius and the number 11 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 11, a master number
Born on the 11th, your birthday number is 11 itself, a master number the Almanac keeps whole rather than reducing it to 2: an 11 vibration is a Master Number connected to intuition, inspiration, sensitivity, and vision, with vision and inspired perception as its gift and nervous intensity, overwhelm, or self-doubt as its strain. On an ordinary day the 11 is lived through its 2, and a 2 vibration supports sensitivity, partnership, diplomacy, and careful listening.
Your 2027 numbers
For a birthday on December 11 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 11th keeps its master 11, and 3 + 11 + 11 = 25, which reduces to 7, so 2027 is your Personal Year 7.
A Personal Year 7 is read as a year of reflection, study and rest, when the inner life asks for more room than the calendar. With 2027 a Universal Year 11 the tradition reads it as a year of real insight for anyone who makes time to be quiet.
Personal Months of 2027, a Personal Year 7: Jan 8 Feb 9 Mar 1 Apr 11 May 3 Jun 4 Jul 5 Aug 6 Sep 7 Oct 8 Nov 9 Dec 1
In 2027 December 11 falls on a Saturday, the day the old reckoning gives to Saturn, and is a Personal Day 3 (1 + 11 = 12, then 3) in a Personal Month 1 (7 + 12 = 19, then 1), while April 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.
