Rising sign and birth chart calculations depend on your birth time and city as well as your birth date. The ascendant changes roughly every two hours, so a 30-minute difference in birth time can change the result. The tools compute planetary positions from astronomical ephemeris data. If you do not know your birth time, you can request your birth record from the civil registry office.
In astrology, the Moon sign is read as your emotional responses, the rising sign as the face you show the world and the Sun sign as your core identity; together they are called the big three. The compatibility tool scores two signs on element and modality harmony. The Chinese zodiac uses the 12-animal yearly cycle, and the tool accounts for the Chinese New Year date for January and February birthdays.
Astrology is not a scientifically validated system. These tools calculate the rules of a cultural tradition, for entertainment and self-reflection. Do not base major life decisions on chart readings.
