In every one of the 91 years from 1940 to 2030 the Sun stood in Sagittarius for the whole of December 1, in every time zone on Earth, between 8.4° and 9.8° of the sign at noon UTC, so a December 1 birthday is a Sagittarius birthday whatever the year or the hour.

At noon UTC on December 1 the Sun is in the first decan of Sagittarius, 0° to 10°, in every one of those years, a face that belongs to Mercury in the Chaldean order and is read through Sagittarius, ruled by Jupiter, by triplicity; in most years the decan runs from November 22 to December 1, and December 1 is its tenth day.

In most years December 1 is the 10th day of the Sun’s season in Sagittarius, which runs from November 22 to December 21 counted at noon UTC, with 20 days of it still to come. December 1 is the 335th day of a common year and the 336th of a leap year, with 30 days of the year still to come after it.

December 1 birthday personality

Mercury opens Sagittarius in the Chaldean scheme while Jupiter keeps it by triplicity, so the archer’s reach is read as an intellectual one: the reader, the traveller with a notebook, the one who keeps asking why. Its caution is a frankness that forgets its audience.

Born on the 1st, you carry the number in its plainest form, with no compound behind it, only the 1 of beginnings. Numerologists read the first of the month as the self-starter, someone who would rather go first than wait to be asked. In a fire sign the 1 doubles the urge to begin, so the tradition reads a born initiator who is happiest with a fresh start in hand.

A question to carry from December 1: where could your hope make the first move you have been waiting for someone else to make?

The Sun in Sagittarius and the number 1 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 1

Born on the 1st, your birthday number is simply 1, the day itself: a 1 vibration supports initiative, courage, leadership, and clear beginnings, with initiative and self-direction as its gift and impatience, isolation, or ego pressure as its strain.

For a birthday on December 1 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 1st gives 1, and 3 + 1 + 11 = 15, which reduces to 6, so 2027 is your Personal Year 6.

A Personal Year 6 is read as a year of love and duty, of home, family and the people who rely on you. In 2027, a Universal Year 11, the tradition reads that care as reaching out to heal and to serve a community.

Personal Months of 2027, a Personal Year 6: Jan 7 Feb 8 Mar 9 Apr 1 May 11 Jun 3 Jul 4 Aug 5 Sep 6 Oct 7 Nov 8 Dec 9

In 2027 December 1 falls on a Wednesday, the day the old reckoning gives to Mercury, and is a Personal Day 1 (9 + 1 = 10, then 1) in a Personal Month 9 (6 + 12 = 18, then 9), while May 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.
