Why your birth time matters
Your Sun sign needs only your birth date, and your Moon sign almost always does too. Your Rising sign is different: it is the sign on the eastern horizon at your birth place, and it changes about every two hours.
Here is Chiara's birthday drawn twice, at 08:00 and at 20:00. Line the signs up to see what twelve hours changed: her Rising sign went from 3°45′ Scorpio to 11°17′ Gemini.

Each chart puts its own Ascendant on the left, so the zodiac looks turned between them.

Questions about the calculator
Short answers. The full reading comes with your result.
The Big 3 are your Sun, Moon and Rising signs. The Sun is your core identity, the Moon is how you feel and what you need, and the Rising sign is the first impression you give.
Your Sun sign needs only your birth date. Your Moon sign is best with the time, because the Moon changes sign about every two and a half days. Your Rising sign changes about every two hours, so it needs your birth time and your birth place.
It is the zodiac sign that was rising over the eastern horizon at your birth place at the moment you were born. That is why the same date gives different Rising signs at different times of day.
People born within a day of a sign change can land on either side of it, depending on the year, the hour and the time zone. This calculator uses your exact date, time and place, so it gives the sign the Sun was really in.
A few minutes either way rarely changes your Sun or Moon sign. Your Rising sign can change in about two hours, so if your time is uncertain, try the earliest and latest times it could have been and compare.
