Create a natal chart
Use a nickname, birth date, time accuracy, and birthplace. A legal name is never required.
How Shared Sky works
From birth details to useful conversation.
Create a chart first. Pair two people with permission. Read the pattern in plain language, then inspect the evidence whenever you want.
See what the data supports
Full, Partial, and Date-stable results say clearly which houses, angles, and Moon details are available.
Pair people with permission
Invite another adult, attest current permission, or confirm guardian authority for a child.
Read insight and evidence
Each report balances resources and stretch points, then links every major statement to chart factors.
Birth-time accuracy
Useful, even when the time is not known.
Full chart
Recorded or trusted exact time. Supported houses, angles, and overlays are available.
Partial chart
Remembered or estimated time. Only factors stable across the uncertainty window remain.
Date-stable only
No reliable time. Houses and angles are omitted; stable planet-to-planet patterns remain.
Current calculation profile
Western tropical astrology, versioned.
Whole Sign houses are used when the birth time supports them. Five major aspects are shown: conjunction, opposition, square, trine, and sextile.
Placidus houses and true lunar nodes remain unavailable until independent validation is complete. Old saved reports never silently change when the method changes.
No compatibility scoreA single number creates false precision. Reports use balanced resources, recurring stretch points, confidence notes, and practical actions instead.
