Why the pages all agree and all say little
A sun sign follows from a date range, and date ranges can be printed once and reused for ever. That makes them cheap to publish and slightly wrong at the edges, since the true ingress moves by up to a day and a half between years. For a date in the middle of a sign the wrongness never shows, which is why nobody notices.
The degree is different. It has to be computed for a specific year, and it changes the description in a way a sign label cannot. Two Cancer birthdays three weeks apart share a word and very little else in the older technical material.
The figure for this date
At noon in each year from 1930 to 2035, the Sun on 6 July stood between about thirteen and a half and fifteen degrees of Cancer. Fourteen and a half is a fair single figure for it, and the entire century of variation is contained in a band of roughly a degree and a half.
That stability comes from the leap year cycle. Each common year the Sun reaches a given longitude about six hours later by the clock, and each leap February pulls the calendar back by close to a day. The two effects run against each other and mostly cancel, leaving only a small residual swing.
The gap can be quoted in days as well as degrees, which is the form most people find easier to check. Fourteen and a half degrees of Cancer sits about fifteen days after the Sun entered the sign and about sixteen before it leaves. Anyone who has been told they are a Gemini Cancer cusp on the strength of an early July birthday can put the claim against that: a cusp argument needs a gap measured in hours, and this one is measured in a fortnight either way.
Fourteen degrees, and what tradition attaches to it
Fourteen and a half degrees sits in the second face of Cancer, the band from ten to twenty. The Chaldean order assigns that face to Mercury; the triplicity scheme assigns it to Scorpio and hence to Mars. It also sits just short of fifteen degrees, the exact midpoint of the sign, which older sources treat as the most concentrated part of a sign's character.
All of that is inherited reading rather than measurement, and it is worth keeping the two apart. The measurable claim is the longitude. What the tradition builds on top of the longitude is a separate matter that the reader is free to take or leave.
The honest edge of what a date can do
The date does not fix the Moon, which shifts sign every two or three days and can change during a single 6 July. It does not fix the ascendant, which depends on the minute and the latitude of birth and turns through all twelve signs daily. It says nothing whatever about a person's life, and this site does not pretend otherwise.
What it does give is a precise solar position and the face that position falls in. The widget above turns the range into a single figure using your year, hour and birthplace, and reports how many degrees you were born from the nearest sign boundary.
What the widget adds over a printed range is the year. A range is written once and reused, so it cannot know that the ingress moment for your particular year fell where it did, and it cannot report a distance at all. Given a year, an hour and a birthplace the widget returns one longitude and the margin to the nearest boundary, which is the number that decides whether any of this is close.
Questions people ask about this
Is 6 July Cancer or Leo?
Cancer, in every year of the sample. The Sun does not reach Leo until around 22 July, and even the earliest ingress in the period leaves this date well inside Cancer.
Why does every site say the same thing about this birthday?
Because a sun sign can be read off a fixed date range with no calculation, so the same paragraph is reproduced endlessly. Anything more specific requires computing a position for a particular year.
What is the Sun's degree on 6 July?
Roughly thirteen and a half to fifteen degrees of Cancer at noon across the sampled century. The widget above reduces that to your own single value.
What does being near fifteen degrees mean?
Fifteen degrees is the exact middle of a sign, and older sources treat the midpoint as where a sign's qualities are least diluted by its neighbours. That is a traditional reading, not a measurement.
Which decan applies?
The second decan of Cancer. Chaldean order puts Mercury on it and the triplicity scheme puts Mars there through Scorpio.
Does the sun sign describe my personality?
This site does not make that claim. It reports where the Sun stood and what the tradition has attached to that position, and leaves the reader to judge the attachment.
