OpenAstrology studies the position of the heavenly bodies at the moment of your birth to draw a profile and cycle indicators. This Tarotoui hub focuses on astrology tools only: birth chart, ascendant, moon sign, sun sign, zodiac compatibility, lunar calendar and biorhythms.
What is astrology?
Western astrology comes from the Babylonian tradition of the second millennium BCE, transmitted through Hellenistic Greece. It distinguishes the sun sign, linked to the Sun's position, the ascendant, calculated from birth time and place, and the moon sign, linked to the Moon's position. These elements are read together to understand temperament, personal cycles and relationship dynamics.
How does a calculation unfold?
For a complete birth chart, you enter your date, precise time and place of birth. The calculation places the planets in the signs and astrological houses. The ascendant requires reliable birth time because it changes quickly during the day. The sun sign, moon sign, compatibility, lunar calendar and biorhythm tools use the data needed for each reading.
Getting the most out of astrology
Do not reduce your profile to one sign: a full birth chart gives a more nuanced reading. Check your time of birth on an official record when possible, especially for the ascendant. Use zodiac compatibility as a reflection aid, not as a verdict. The lunar calendar and biorhythms can help you observe rhythms without replacing personal judgment.
Frequently asked questions
Why is the time of birth important?
Because the ascendant and astrological houses depend directly on birth time and place. An approximate time can change the interpretation.
What is the difference between sun sign, moon sign and ascendant?
The sun sign describes the main axis of identity, the moon sign speaks more about sensitivity and emotional needs, and the ascendant colors the way you meet the world.
Is zodiac compatibility enough to judge a relationship?
No. It highlights possible affinities and tensions, but a relationship also depends on communication, context and each person's choices.
What are biorhythms?
Biorhythms describe three indicative cycles, physical, emotional and intellectual, calculated from the date of birth. They are offered as a symbolic observation tool.
