The settled part, stated once
At noon between 1930 and 2035 the Sun on this date has stood between about twenty point eight and twenty two point two degrees of Leo. Both ends of that window are above the twenty degree line, so the final band of the sign applies in every year, without a caveat.
That band belongs to Mars. The Chaldean count arrives there by running the planets in order of apparent speed from the opening of Aries; the triplicity scheme arrives there through Aries, the first of the fire signs. Agreement between the two is the exception rather than the rule, and Leo's closing degrees are one of the places it happens.
The Moon is not fixed by a date
The Moon moves between twelve and fifteen degrees in twenty four hours, roughly thirteen times faster than the Sun. A sign is thirty degrees wide, so the Moon spends between two and two and a half days in each one, and any given calendar date has a fair chance of containing a change of sign.
What that means in practice is that two people born on the same fourteenth of August, one at breakfast and one at midnight, can have their Moon in different signs. The date does not narrow it to one, and no page that works from dates alone can tell you which you have.
The rising sign is not narrowed at all
The Ascendant is the point of the ecliptic coming over the eastern horizon at the moment of birth. The Earth turns once in a day, so all twelve signs rise in that period and the Ascendant can be any of them regardless of the date.
It is also the placement most sensitive to where the birth happened. Signs rise at very uneven speeds away from the equator, and at high latitudes some take well over two hours to clear the horizon while others take a fraction of that. Two births at the same clock time in different cities can therefore have different rising signs, which is why the birthplace is asked for and not just the country.
None of this makes the rising sign mysterious. It is a straightforward calculation from the time, the date and the coordinates of the birthplace, and it has been done by hand for centuries. What it cannot be is guessed, which is the difference between a placement a calendar can supply and one it cannot.
Why this ordering matters
The sun sign is the placement a date does fix, and it is also the broadest. Roughly a twelfth of everyone alive shares it, which is a poor basis for a description of an individual. The decan cuts that to a thirtieth, and the degree cuts it much further, but the parts that genuinely vary from person to person are the ones the calendar cannot supply.
The widget above asks for the year, the hour and the place because those are the inputs the calculation actually needs. It returns the exact solar degree instead of a range, states the distance from the nearest sign boundary, and works out the Moon and the Ascendant, which is where a chart starts to say something specific.
Questions people ask about this
What sign is 14 August?
Leo, in every year. The Virgo boundary falls around the twenty second of August, so this date has never come close to it in modern times.
Which decan is a 14 August birthday in?
The third decan of Leo, from twenty to thirty degrees. The date's whole range across the last century sits above the line, so the band is not year dependent here.
Can I know my Moon sign from the date alone?
No. The Moon changes sign every two days or so, and on many dates the change happens partway through, so the hour and the time zone are both needed.
Does my birthplace really change the rising sign?
Yes. Latitude affects how quickly each sign clears the horizon, so the same clock time in two cities can produce different Ascendants.
What if I do not know my birth time?
The sun sign and decan still hold, since neither is close to an edge on this date. For the Moon and the Ascendant, an unknown time means a range rather than an answer.
What is the solar degree on 14 August?
Between about twenty point eight and twenty two point two degrees of Leo at noon, depending on the year. The exact figure needs the hour and the birthplace.
