What the date does fix
At noon on 4 November the Sun sits close to twelve degrees of Scorpio, running between about 11.1 and 12.5 across the years from 1930 to 2035. That puts it in the middle face of the sign, the band from ten to twenty degrees, in every year of that span with room to spare.
Both of those are properties of the date rather than of the person. The longitude is where the Earth happens to be in its orbit at the start of November, and the face is a division of the ecliptic that has been drawn the same way since antiquity. Nothing about them varies with the hour, which is exactly why a page can state them without knowing anything else about you.
The Moon, narrowed to a couple of options
The Moon crosses about thirteen degrees of the ecliptic a day, so it stays in a sign for a little over two days and then moves on. On any given 4 November it will be somewhere in a two or three sign window depending on the year, and in a fair number of years it changes sign partway through the day.
That means the lunar sign is a question the date narrows and does not answer. It is also the placement that most descriptions of a birthday quietly borrow from, since the emotional register people expect from a chart reading comes from the Moon more than the Sun. Attributing it to the date is a category error, and an easy one to spot once you know how fast the Moon moves.
The Ascendant, untouched by the date
The rising sign is the point of the ecliptic on 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 Ascendant changes sign roughly every two hours.
This makes it a function of the clock and the place, not of the calendar. Two people born on 4 November in the same city eight hours apart will have Ascendants four signs distant. Two born at the same instant in different longitudes will differ as well. Where the Sun is a coordinate on a slow moving orbit, the Ascendant is a coordinate on a spinning planet, and it is the placement that decides which houses everything else falls into.
So what is a birthday page for
It can state the sun sign, the solar degree and the face, and it can say what the tradition attaches to each of them. It can also say where the boundaries are, so you know whether your own position is comfortably inside a band or close to the edge of one.
What it cannot do is describe a person. The date supplies the slowest and least individual of the personal placements, and the ones that vary between people born hours apart are precisely the ones a date cannot supply. The widget above closes that gap by taking a year, a time and a birthplace, which is the minimum a chart calculation needs and the maximum a page written in advance can never have.
Questions people ask about this
What sign is a 4 November birthday?
Scorpio in every year. The nearest sign boundary is about eighteen days away at the Sagittarius crossing, so there is no ambiguity of the kind that affects dates near the edges of a sign.
What is the solar degree on 4 November?
Around twelve degrees of Scorpio, with noon values between roughly 11.1 and 12.5 across 1930 to 2035. Your own figure depends on the year, hour and place.
Which decan is it?
The second face of Scorpio, ten to twenty degrees. The Chaldean order gives that band to the Sun and the triplicity scheme gives it to Pisces.
Can I know my moon sign from the date alone?
Only within two or three options. The Moon changes sign every two and a bit days and frequently crosses during the day itself, so the hour is what decides it.
Does my rising sign depend on the date?
No. It depends on the time and the place of birth, and it moves through all twelve signs in a day. Any of the twelve is possible on this date.
Why do so many birthday descriptions sound specific?
Because they describe the sun sign as though it were the whole chart. The placements that differentiate people born on the same day are the fast ones, and a date does not contain them.
