May 31 zodiac sign: Gemini

Sun sign

Gemini

Sun at noon UTC

9.2° to 10.6° Gemini

Decan

First of Gemini, 0° to 10°

Element and mode

Air, mutable

Ruling planet

Mercury

In every one of the 91 years from 1940 to 2030 the Sun stood in Gemini for the whole of May 31, in every time zone on Earth, between 9.2° and 10.6° of the sign at noon UTC, so a May 31 birthday is a Gemini birthday whatever the year or the hour.

At noon UTC on May 31 the Sun is in the first decan of Gemini in 59 of those years and in the second in 32, so the decan, like the sign at a cusp, turns on the year. The first decan of Gemini is a face that belongs to Jupiter in the Chaldean order and is read through Gemini, ruled by Mercury, by triplicity, and in most years the decan runs from May 21 to May 31, and May 31 is its eleventh day.

In most years May 31 is the 11th day of the Sun’s season in Gemini, which runs from May 21 to June 21 counted at noon UTC, with 21 days of it still to come. May 31 is the 151st day of a common year and the 152nd of a leap year, with 214 days of the year still to come after it.

May 31 birthday personality

Jupiter opens Gemini in the Chaldean order and Mercury keeps it by triplicity, so a birthday here is read as curiosity with an appetite for meaning, the student who wants the whole library. The tradition’s warning is a breadth that never settles long enough to become knowledge.

The 31st adds 3 and 1 into 4, so numerology reads the creative and the independent settling into a builder’s discipline. It is a birthday linked with practical originality. In air the 4’s structure is read as system and order of thought, the planner who builds frameworks out of ideas.

A question to carry from May 31: what would your curiosity build if you gave it one hour, every day, for a month?

The Sun in Gemini and the number 4 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 4

Born on the 31st, 3 + 1 = 4, so your birthday number is 4: a 4 vibration supports structure, discipline, foundations, work, and stability, with structure and reliability as its gift and rigidity, fear, or over-control as its strain.

Your 2027 numbers

For a birthday on May 31 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: May, the 5th month, gives 5, the 31st reduces to 4, and 5 + 4 + 11 = 20, which reduces to 2, so 2027 is your Personal Year 2.

Read as the quiet year of the nine, a Personal Year 2 asks for cooperation, patience and attention to detail rather than big moves. In 2027, whose Universal Year 11 also rests on a 2, the reading leans toward partnerships and toward trusting a slower pace.

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 May 31 falls on a Monday, the day the old reckoning gives to the Moon, and is a Personal Day 11 (7 + 31 = 38, then 11) in a Personal Month 7 (2 + 5 = 7), while September is a master month 11; the Personal Year itself turns on 1 January, not on the birthday.
