What a December 30 birthday means
On December 30 the Sun sits between 7.4° Capricorn and 9.7° Capricorn in every year from 1950 to 2025, counting every hour of the day in UTC. Its usual noon position is 8.6° Capricorn.
That places December 30 in the first decan of Capricorn. The modern triplicity system gives this decan to Capricorn, the older Chaldean order gives it to Jupiter, and the Golden Dawn tradition pairs it with the Two of Pentacles.
Capricorn is an earth sign of the cardinal modality, ruled by Saturn. Earth signs trust what they can touch, count and build on. Cardinal signs start things: each one opens a season.
December 30 is about 8 days from the nearest sign change, so the Sun is in Capricorn 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 December 30 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.
