The part that is settled
Taking noon in every year from 1930 to 2035, the Sun on 29 November has sat between about six and a third and seven and two thirds degrees of Sagittarius. The sign was crossed into more than a week earlier, so no hour of birth and no time zone can move the answer.
That band is tight because the leap year cycle keeps the calendar and the orbit in step. The Sun arrives about six hours later against the calendar each ordinary year and is pulled back by nearly a day at each leap day, leaving a residue small enough to ignore for this purpose.
Seven degrees also places the position in the first decan of Sagittarius, the opening ten degrees, which the Chaldean order assigns to Mercury and the triplicity scheme to Jupiter. That is the last thing a date alone will tell you.
The Moon, which the hour decides
The Moon crosses roughly thirteen degrees a day and changes sign every two and a bit days. On any given calendar date it will therefore be in one of two signs, and a birth near the changeover falls into a third if the year is right.
There is no way to narrow this from the date. Someone born at breakfast and someone born at midnight on the same 29 November can have Moons in different signs, and the Moon is the placement the tradition ties most closely to temperament and to what a person needs rather than what they pursue.
An approximate answer is available from a date and a place, since the Moon spends most of a day in one sign. An exact answer needs the time, and a result close to a lunar ingress should be treated as provisional until the time is found.
The rising sign, which the date cannot touch
The Ascendant is the degree of the zodiac coming over the eastern horizon at the moment of birth. The Earth turns once a day, so the whole zodiac passes that point in twenty four hours and the rising degree changes by roughly one degree every four minutes.
That makes the Ascendant the placement where a birthday is worth nothing at all. Two people born on this date in the same city, four hours apart, have different rising signs, and every planet in their charts falls into a different house as a result.
Houses are where a reading becomes specific about areas of life rather than about disposition, so losing the Ascendant is not a minor gap. It is the difference between a description that could apply to a twelfth of the population and one that could not.
Why the sun sign is the least personal part
Everyone born within about thirty days of you shares your sun sign. Nothing in a chart is held in common by that many people, which is precisely why sun sign writing has to stay general, and why two people with the same birthday can find the same description convincing and useless at once.
The Sun still matters. It is the fastest way to locate a chart in the year, it carries a long interpretive tradition, and its degree governs which aspects it makes. It simply is not the personal layer, and treating it as one is the reason so much popular astrology reads as vague.
The widget above computes your exact solar degree from your own year and birthplace, and reports how far you were born from the nearest sign boundary. For this date that distance is large. Once you have that, the next thing worth finding is your birth time, because everything above depends on it.
Questions people ask about this
Is 29 November definitely Sagittarius?
Yes. The Sun is around seven degrees into the sign at noon in every year checked, which puts it well beyond the reach of any calendar drift or time zone difference.
What Moon sign goes with this birthday?
That depends entirely on the year and the hour. The Moon changes sign every couple of days, so a date alone narrows it to two possibilities at best.
Can I find my rising sign without a birth time?
Not exactly, though the range can be narrowed if you know roughly what part of the day you were born in. A birth certificate or a hospital record is the usual source.
Does my birthday tell me anything beyond the Sun?
It fixes the solar degree and therefore the decan, and it gives an approximate Moon. Everything else in the chart needs a time and a place as well.
Why do sun sign descriptions feel half right?
Because they describe something a twelfth of the population shares. The parts that feel wrong are usually being supplied by placements the description never had access to.
What decan is a 29 November Sun in?
The first decan of Sagittarius, ruled by Mercury in the Chaldean order and by Jupiter under the triplicity scheme.
