The part the date does settle
Sampling noon in each year from 1930 to 2035, the Sun on this date stood between roughly twelve and a half and fourteen degrees of Cancer. That places it in the second face of the sign, the ten to twenty degree band, in every one of those years.
Chaldean order gives that face to Mercury and the triplicity scheme gives it to Mars by way of Scorpio. The sign itself is cardinal water with the Moon as ruler. Those are the fixed points, and the list is shorter than most birthday pages imply.
The Moon is genuinely uncertain
The Moon moves roughly twelve to fifteen degrees a day, which means it changes sign every two and a bit days and can cross a boundary in the middle of any given 5 July. A birth in the small hours and a birth at bedtime can therefore carry different Moon signs on the same date in the same year.
Across different years the situation is wider still. The Moon has no reason to return to the same sign on this calendar date, so over a century it visits all twelve. Anyone telling you what the Moon says about your birthday, from the date alone, is describing nothing.
The rising sign is wide open
The ascendant is the degree of the zodiac coming up over the eastern horizon at the moment of birth, and the horizon sweeps the whole circle once a day. Four minutes of clock time shifts it by about a degree, and the rate is uneven because signs rise at different speeds depending on latitude.
So the ascendant depends on the hour, the minute and the place, none of which a date carries. Where the birth time is genuinely unknown, a rectified or approximate ascendant should be treated as a hypothesis rather than a reading. The whole house structure of a chart rests on it.
Numbers help here more than adjectives. For the Moon on this date the realistic answer is one sign, or two if the boundary falls inside the day, out of twelve possible across different years. For the ascendant it is all twelve every year, with the sign changing roughly every two hours and the exact degree changing about once every four minutes. Neither figure narrows without the hour, and the second does not narrow without the birthplace either, since the rising sign depends on latitude as well as clock time.
Why this is a better answer than it sounds
Being told what a date cannot decide is more useful than being handed confident detail that was never in the data. It tells you which extra facts are worth going and finding: the hour on a birth certificate is often the single item that converts a vague chart into a definite one.
The widget above works on exactly that basis. Give it a year, a time and a birthplace, and it returns your solar degree rather than a range, along with how far you were born from the nearest sign boundary. Where the time is missing it falls back to noon, and on this date noon is safe for the sign though not for the Moon or the ascendant.
This is also the gap between the widget above and a date range. A range answers one question, which sign, and answers it the same way for everyone born inside a month long window. The widget takes the year, the hour and the place and returns a single longitude rather than a band, along with the distance in degrees to the nearest boundary, which is the figure that tells you whether the label you have been given is secure or marginal. On this date it is secure, and knowing that is worth more than being told it.
Questions people ask about this
What sign is a 5 July birthday?
Cancer, settled. The nearest boundary is the move into Leo around 22 July, which is more than two weeks of solar motion away from this date.
Can the Moon sign be worked out from my birthday?
No. The Moon changes sign every two or three days, so a single date leaves at least two possibilities and often more once different years are considered.
How much does the rising sign depend on birth time?
Entirely. It advances roughly a degree every four minutes and completes the zodiac in a day, so an hour of error can move it into the neighbouring sign.
What is fixed by this date?
The sun sign, the solar degree to within about a degree and a half, and therefore the decan. Those are the three things this page states without hedging.
Which decan is 5 July in?
The second decan of Cancer, from ten to twenty degrees. Mercury rules it in the Chaldean order and Mars does so in the triplicity scheme.
If I do not know my birth time, is a chart worth casting?
Partly. The planetary positions other than the Moon are close enough at noon to be useful, while the houses and the ascendant should be left out rather than guessed.
