Capricorn/Sagittarius
Western (tropical) Capricorn · Vedic (sidereal) Sagittarius
You at a glance
Born on December 31st, you read as Capricorn in the Western tropical zodiac and Sagittarius in the Vedic sidereal system. The two-signs-back pattern (Lahiri ayanamsa shifts most birthdays one sign earlier in Vedic) is the norm, not an anomaly. Most people growing up with Western horoscopes will feel the Capricorn description fits — until they meet a Jyotishi who reads the Sagittarius chart and finds it equally accurate from a different angle.
The year ahead
The year ahead carries the standard Sun-themed maturity arc that a Capricorn birthday rotates through annually. Saturn's current sidereal position colors the long themes; transiting Jupiter shapes the seasons of expansion.

Birthday note
December 31st shares a birthday with notable Capricorn figures across history — from artists and inventors to spiritual teachers. The shared Sun placement explains some of the temperamental kinship, though the rest of any chart shapes the actual life arc.
