What an October 13 birthday means
On October 13 the Sun sits between 18.8° Libra and 21.1° Libra in every year from 1950 to 2025, counting every hour of the day in UTC. Its usual noon position is 19.9° Libra.
That places October 13 in the second decan of Libra. The modern triplicity system gives this decan to Aquarius, the older Chaldean order gives it to Saturn, and the Golden Dawn tradition pairs it with the Three of Swords. In some years the Sun moves on into the third decan of Libra during this date, so both apply.
Libra is an air sign of the cardinal modality, ruled by Venus. Air signs think in conversations and connections; ideas are how they move. Cardinal signs start things: each one opens a season.
October 13 is about 9 days from the nearest sign change, so the Sun is in Libra on this date in every year charted.
Where these figures come from
The Sun's position was charted at 12:00 UTC on every day from 1950 to 2025, and the start and end of each date were placed on the straight line between neighbouring days, which is exact to a small fraction of a degree. The range covers every hour of October 13 in UTC across all 76 years; someone born far from UTC can sit up to about half a degree beyond it. Decans follow two traditional systems: the triplicity system, which gives each third of a sign to the three signs of its element in turn, and the older Chaldean order of faces, which runs through the seven classical planets from Mars at the start of Aries.
