Rising sign and birth chart calculations depend not just on your birth date but on the time and city: the ascendant changes roughly every two hours, so a 30-minute difference in birth time can shift the result. Our tools compute planetary positions from astronomical ephemeris data; if you do not know your birth time, your civil registry office can provide the birth record.
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 element and modality harmony between two signs. The Chinese zodiac uses the 12-animal yearly cycle and accounts for the Chinese New Year date for January and February birthdays.
Astrology is not a scientifically validated system; these tools compute a cultural tradition with correct formulas, for entertainment and self-reflection. Do not base major life decisions on chart readings.
