December 20 zodiac sign: Sagittarius
The December 20 zodiac sign is Sagittarius at midday in every year from 1930 to 2029 — but not at every hour: in 5 of those 100 years a birth at the end of the day, in time zones well behind Greenwich, had the Sun already in Capricorn.

Saturn narrows and hardens the sign, making it slower to commit and more durable once it has. The last ten degrees of Sagittarius already turn toward Capricorn, which is why this third often reads as the most complicated.

The Moon and nakshatra columns change every year because the Moon returns to the same calendar date in a different position — which is why a birth date alone cannot tell you those, and why this table exists.

The most frequent is 9 with 12 years; every other number, 11 included, turns up in 11 years. And this date can carry a master number: 11 in 11 of those years — kept whole rather than reduced. Why 11, 22 and 33 are treated differently →
Why the answer almost always holds
December 20 sits 28 days past the start of Sagittarius and reached 28°36′ this year — close enough to the end of the sign that the hour starts to count: in 5 of those 100 years a birth at the end of the day, in time zones well behind Greenwich, had the Sun already in Capricorn. At midday it is Sagittarius in every year tested, so on this date the question worth asking is the birth time, not the birth year.
