Fifty five to fifty one
A four year margin over more than a century is not a preference, it is noise. On this date the two answers occur at effectively the same rate, and the sign someone born on 22 November was told they were depends mostly on which book their parents owned.
The balance comes from where the boundary sits relative to the calendar. Because the tropical year is roughly a quarter of a day longer than the year we count, the moment the Sun reaches two hundred and forty degrees of ecliptic longitude falls about six hours later each year, then jumps back by some eighteen hours when February gains a day. Over a decade that sawing motion carries the ingress across about a day and a half, and 22 November lies almost exactly in the centre of the swept range. It is caught by each side about as often.
Only the hour and the place will finish it
On a date this balanced, the year is the first fact and it is rarely the last. In a great many of these years the ingress happens somewhere within 22 November itself, so a birth at dawn and a birth at midnight on the same day are different signs. A birth time is not a refinement here, it is part of the answer.
The birthplace does the rest. An ingress is one instant for the entire world and only the local clock reading differs, so a change at 02:00 UTC on 22 November has already happened by nine on the evening of the twenty first in New York. A birth there at ten that night is Sagittarius while a birth at the same absolute moment in Amsterdam is still Scorpio. Almost every wrongly reported sun sign traces back to a table built for one meridian and applied to another.
Nothing occupies the boundary
This date is written about as a cusp more than most, and the sketches tend to promise depth combined with restlessness. The Sun has no way to be both. It holds one ecliptic longitude at any instant, either short of two hundred and forty degrees or beyond it, so a birth an hour before the change is entirely Scorpio and one an hour later entirely Sagittarius.
Cusp is best understood as a label for a birth record that was never finished. It says the year, the hour or the place is missing, and it has nothing left to describe once they are supplied. The widget above supplies them and reports how many hours from the boundary the birth actually fell, which on this date is the number worth knowing.
Mars and Jupiter next door
Scorpio is fixed water, traditionally ruled by Mars and given to Pluto in much modern practice. Sagittarius is mutable fire under Jupiter. There is no shared ruler, and in the older scheme the pair sit as the night house of Mars beside the day house of Jupiter, which the tradition treats as a marked change of temperature rather than a gradient.
Even so, they are not the opposites the popular versions describe. Both are read as unwilling to settle for the surface account of anything, one by investigating what is concealed and the other by asking what it all amounts to. Both are also credited with a bluntness that surprises people expecting tact.
Whichever answer the calculation returns, only the Sun is affected. The Moon, the Ascendant, the planets and the houses are computed the same way and do not shift because one longitude fell on the other side of a line.
Questions people ask about this
Is 22 November Scorpio or Sagittarius?
Almost exactly as often one as the other. At noon between 1930 and 2035 the tally was fifty five years Scorpio to fifty one Sagittarius, which is too close to call from a date alone.
Why is this date so evenly divided?
Because the ingress drifts across a window of roughly a day and a half and 22 November sits near the middle of it. The date is caught on either side of the boundary at a similar rate.
Is my birth time essential here?
Close to it. In many of these years the boundary falls during 22 November itself, so morning and evening births on the same day come out as different signs.
Am I on the Scorpio Sagittarius cusp?
No, because that is not a state the Sun can be in. It occupies one longitude at a time, inside one sign. The word marks information nobody established rather than a blend.
What if my birth time is unknown?
The calculation falls back to noon, which on this date is frequently the wrong side. If the result comes back within a few hours of the boundary, treat it as open until the time is found.
I was told one sign as a child and get the other now. Which is right?
The calculated one, provided the year, hour and place given to it are correct. The childhood answer almost always came from a fixed range that could not account for any of those.
