What information do I need for a Human Design chart?
You need three pieces of information: your birth date (day, month, year), your birth time (as precise as possible — even 15 minutes can shift the chart), and your birth location (city and country). With those three, a complete BodyGraph — Type, Authority, Profile, all nine Centers, 64 Gates, and Incarnation Cross — can be generated instantly.
Birth time is the most sensitive input; if you're unsure of yours, check a birth certificate or hospital record, or ask a family member — even an approximate time (morning, afternoon, evening) gives useful information, just with more uncertainty around a handful of border-case Gates.

- What if I don't know my exact birth time?
- Check your birth certificate or hospital record, or ask a family member. Even an approximate time still produces a mostly reliable chart.
- Does birth location matter?
- Yes — it's needed to calculate the correct time zone and, in some systems, house placements, both of which affect the underlying planetary calculation.
- Is generating a chart free?
- Yes — Human Design Core generates a complete BodyGraph, including Type, Authority, Profile, Centers, Gates, and Incarnation Cross, for free with no account required.
