December zodiac signs
December birthdays fall in Sagittarius or Capricorn. Pick a day for its sign, the Sun’s exact degree and decan, and a short profile.
Sagittarius and Capricorn
December is shared by two signs. The Sun spends the first three weeks in Sagittarius, the mutable fire sign ruled by Jupiter, and crosses into Capricorn, the cardinal earth sign ruled by Saturn, around the 21st or 22nd. Birthdays on those two dates can belong to either sign, so their pages carry a computed table by year.
The Sagittarius part of the month is restless and outspoken: big questions, plans for travel and a fondness for blunt honesty, with Mars sharpening the middle decan and the Sun warming the last one with pride and showmanship. The final ten days turn quieter and more deliberate. Capricorn’s first decan is ruled twice by Saturn, and it asks for structure, patience and results that last well beyond the holidays.

Decans here follow the triplicity system: each sign’s first ten degrees belong to the sign itself, the next ten to the next sign of the same element, the last ten to the third. Each decan’s sub-ruler is that sign’s ruling planet. Calculated by Lunonis from the same ephemeris code as our charts (astronomy-engine, checked against Swiss Ephemeris): geocentric, tropical zodiac, true equinox of date. Times are UTC: add or subtract your time zone’s offset, which can move the change to the day before or after.
