Born on the 21st: three times seven

The 21 reduces to 3 (2 + 1). It is also 3 × 7, the product of two numbers heavy with symbolism. Authors find in it expression, creativity and communication, with the added idea of fulfilment.

This reading is symbolic and has no scientific validation. For the core of the profile, see the birth day 3 and life path 3.

Calculation: from day 21 to the number 3

The 21 has two digits, which we add together: 2 + 1 = 3. Day 21 therefore counts as 3, and some authors write 21/3 to keep a trace of the raw number as well. Three examples (using the “day, month, year” method from the page how to calculate your life path number):

DateCalculation detailLife path number
21 February 1960day 21 → 3; month 2; year 1960: 1+9+6+0 = 16 → 7; 3+2+7 = 12 → 33
21 August 1960day 21 → 3; month 8; year 1960: 1+9+6+0 = 16 → 7; 3+8+7 = 18 → 99
21 January 1968day 21 → 3; month 1; year 1968: 1+9+6+8 = 24 → 6; 3+1+6 = 10 → 11

Same day (21), but the life path number changes (3, 9 and 1): the day is read separately. Some contemporary authors treat it as a “gift” or a complement to the life path number; others ignore it.

The number 21 in history and culture

The 21 is a triangular number (1 + 2 + … + 6) and the name of a card game, “vingt-et-un”, the ancestor of blackjack. The 21st of June, or sometimes the 20th, is the day of the summer solstice in the Northern Hemisphere, and the Fête de la musique has been held on that day since 1982. In France, the age of majority was 21 until 1974.

A myth has attached itself to the number: that of the “21 grams” of the soul, drawn from an experiment by the American doctor Duncan MacDougall in 1907, who believed he had measured the weight lost by dying patients. It has never been confirmed and is considered to have no scientific value. The 21 is also that of arcanum XXI of the Marseille tarot, The World, the last numbered card of the major arcana.

Traditional symbolism of day 21

The classic portrait is that of a radiant person:

  • Strengths often cited: sociability, creativity, enthusiasm, a sense of celebration.
  • Difficulties often cited: scattered focus, need for attention, projects left half-done.
  • Work in progress often cited: seeing things through rather than multiplying beginnings.

These traits are common: many people recognise themselves in them. This is the Barnum effect.

Day to day: create and share

For the 21, the books cite the arts, communication, entertainment and events. These are illustrations.

A simple idea: choose a project you enjoy, define a minimal version (one page, one piece, one recipe) and finish it before starting another. The fulfilment of the 21 of tradition comes through completion.

Traditional correspondences

These associations vary from one school to another; they are indicative. The planets, elements and stones are those of the reduced number, as given in the most widespread tables.

AreaCommon correspondence
TarotThe World, arcanum XXI
Reduced number3: life path 3 (expression and creativity)
PlanetJupiter
ElementAir or fire, depending on the authors
Stones (modern authors)citrine, aquamarine, sodalite

The link between stones and numbers is a modern, optional association: no ancient tradition imposes it.

Reading this portrait without making it a destiny

Being born on the 21st does not make you an extrovert. Your personal year 3 echoes the reduced number.

  • Which creation makes me lose track of time?
  • What have I recently finished that I am proud of?
  • Who would I like to show it to?

Exercise: finish today something small that has been lying around, and note what you feel.
