How does the calculator work?
It converts your local birth time to Universal Time with the historical time zone of your birth city on that date, including daylight saving time. Then it calculates where the Sun and Moon were along the zodiac with Astronomy Engine, accurate to about one arcminute, and which zodiac sign was rising on the eastern horizon: your Ascendant.
The Ascendant changes sign about every two hours, so it needs your birth time. Without it you still get your Sun sign, and your Moon sign unless the Moon changed sign that day.
Example: someone born on Tuesday, April 3, 1990, at 2:30 PM, in Chicago, Illinois, United States has the Sun in Aries, the Moon in Leo and the Ascendant in Leo.
What are the dates of each Sun sign?
The Sun moves into a new sign around the 20th of each month. The exact day and hour shift a little from year to year, so if you were born near the change, use the calculator above: it works from your exact birth time.
