Accurate Chart Calculation
Human Design requires your exact birth date, time, and place. Even a few minutes can change your type, authority, or profile.
If you do not know your birth time, try these sources: birth certificate, hospital records, or family members. You can also use rectification tools.
Your chart is calculated using astronomical data (Swiss Ephemeris) to determine planetary positions at your birth moment.
Use a reliable calculator like HD Matrix for the most accurate results.
