Your birth chart (also called a natal chart) is a snapshot of where every planet sat in the zodiac at the moment you were born. Each placement describes a different part of you: the Sun is your core identity, the Moon your emotional world, Mercury how you think and communicate, Venus how you love and what you value, Mars how you act and assert. The outer planets — Jupiter through Pluto — shape your growth, discipline, and generational themes.
Most people know their Sun sign. Your full chart is where astrology actually gets personal — two people with the same Sun sign can have completely different Moons, Venus placements, and Mercury styles, which is why they can feel nothing alike.
The calculator runs a VSOP87/NOVAS-class astronomical ephemeris directly in your browser — the same category of calculation used by professional astrology software. Your positions are computed in the tropical zodiac, the system used in Western astrology, and nothing you enter is sent to a server or stored by us.
Your rising sign (Ascendant) and house placements are calculated too — right here, live — once you provide both your exact birth time and birthplace. That's real astronomy, not a paywall: without precise time and location, a rising sign genuinely can't be calculated accurately by anyone, anywhere.
A list of placements is only the beginning — the meaning lives in how they combine. That's what Sync is for: an AI spiritual companion that knows your calculated chart, today's live planetary transits, and speaks to you like a friend who happens to know astrology deeply. The chart is a mirror, not a verdict — your intuition always leads.
