Your sun: Capricorn 6°45′
The sun sits at 6°45′ of Capricorn on this date. That exact degree matters: two people born three days apart in Capricorn have different sun degrees, and the degree is what decides which aspects your sun makes to the rest of your chart. The mountain, time turned into stone stairs. The full portrait: the Capricorn sign guide.
The moon that day: Virgo 8°07′
At noon UTC the moon was in Virgo. Everyone born on December 28 shares this lunar backdrop, but the moon moves roughly half a degree per hour, so if it was near a sign boundary that day, your birth time decides whether it had already moved on. Born within a day of a change? Get your exact chart cast rather than guessing: it takes about a minute. What a moon in Virgo feels like: moon in Virgo.
Born under a waning gibbous
The moon was waning gibbous on your birthday, about 74% illuminated at noon. Astrologers read the sun-moon phase as the rhythm between intention and instinct: new moons start things, full moons peak, waning phases release. It is a fixed fact of your date, it repeats on the 19-year Metonic cycle, and unlike most astrology claims you can verify it in any almanac.

That part cannot be a static page, it has to be computed for you: cast your birth chart, free. The method: how to read your birth chart.
